Today, the Honourable Lawrence MacAulay, Minister of Agriculture and Agri-Food, announced that the CFIA will lead two projects worth $500,000 that use new DNA-based technologies to reduce the quarantine testing time, helping to boost trade and economic competitiveness in the $240 million Canadian fruit tree industry.
"Together with provincial partners and industry, our government is making the investments in innovative science that enables agriculture to be a leading growth sector of Canada's economy. Together we can help meet the world's growing demand for high-quality, sustainable food and help grow our middle class," Minister MacAulay, said.
The first project will dramatically shorten the testing period of seeds, cuttings and bulbs imported into Canada to grow new varieties of plants. With this funding, scientists will use DNA technology to test for all viruses associated with imported plants to get an early indication of any plant diseases present. This approach could reduce the quarantine testing time by up to two and a half years.
The second project streamlines the testing of strawberry plants. Traditionally, multiple tests for viruses are required before exporting strawberry plants to foreign markets. This project will test for multiple viruses in one single test, dramatically reducing the time and cost to get plants to market.
Funding for these projects is provided through a partnership between the CFIA, Genome British Columbia, Summerland Varieties Corporation, Phyto Diagnostics, the British Columbia Cherry Association, and Vineland Research and Innovations Centre.
"Canadian import/export markets will be stronger and more competitive because of these genomics-based tools. Early detection of pathogens and viruses is a vital outcome of genomics and it is being applied across many key economic sectors." Dr. Catalina Lopez-Correa, Chief Scientific Officer and Vice President, Genome British Columbia said.
Council chair Leo Broderick questions the science behind Innate generation 2 potatoes, and added P.E.I. would be better off staying away from the controversy surrounding genetically modified food. He noted P.E.I. is already attracting attention as a producer of genetically modified salmon. READ MORE
This will be the 31st year Sakata has hosted the event, which continues to grow every year.
“We began hosting these trials in the small field in Salinas back in 1986,” said John Nelson, sales and marketing director with the company. “Since, it’s continues to expand with our growing infrastructure and has become our largest vegetable event of the year, showcasing the best of Sakata’s genetics and serving host to our customers, media, retail and more. We look forward to celebrating 40 years of business in NAFTA at this year’s trials.”
Those attending Sakata’s field days this year will see a few new modifications. Most notably, it will be the inaugural year Sakata will host its Woodland (warm-season crops – melon, onion, pepper, tomato, pumpkin, squash, watermelon) trials at the new Woodland Research Station; an investment in land, greenhouses, offices and other facilities slated for completion of the first phases in 2018. To learn more about Sakata’s Woodland development, check out the 40th Anniversary video.
In Salinas (cool-season crops – broccoli, beet, spinach, etc.) trials, customers will be greeted with an updated Broccoli Master. This information-rich piece of literature serves as the ultimate reference guide for all things Sakata broccoli, including ideal varieties for every growing region and other important information for successful broccoli cultivation.
“This will be the third generation of our Broccoli Master, and it has always been well-used by our dealers and growers alike,” said Matt Linder, senior broccoli product manager and Salinas Valley area sales manager. “It contains all the great information you need on our varieties right at your fingertips, and is heavy-duty enough to be kept in your truck or pocket when in the field. It’s been a few years since we’ve had an updated version, so we’re excited to include some great new additions we’ve recently added to our broccoli line, such as Millennium, Diamante, Eastern Magic, Eastern Crown and Emerald Star.”

Since then, Vineland has been turning heads across Canada and internationally with its needs-based innovations. The organization reflects the entire horticulture value chain from farmers to consumers, and they’re not afraid to take big steps to help the industry solve problems.
“We started by understanding what needed to be done and how we needed to work to make a difference, which is real results with real impact from acres in the field to shelf space in the store,” says Vineland’s CEO, Dr. Jim Brandle.
Addressing the labour intensive nature of horticultural production was a need identified early on. Today, machines designed in Vineland’s robotics program and built in Ontario are coming into use in fruit and vegetable greenhouses, which Brandle says will go a long way in helping to keep growers competitive, as well as boost the local manufacturing and automation sector.
Sweet potatoes, okra and Asian eggplant are offering new market opportunities for growers and consumers eager to eat more locally produced food.
And Vineland’s rose breeding program made a big splash earlier this year when its Canadian Shield rose – a trademarked low-maintenance and winter hardy variety bred in Canada – was named Flower of the Year at Canada Blooms.
Another significant milestone was the construction of the largest, most modern horticultural research greenhouse in North America with commercial-scale height and growing rooms dedicated to horticulture, which opened in 2016 and was built around the needs of Canada’s greenhouse vegetable and flower growers.“Today, we’re commercializing innovations, from the Canadian Shield rose to new apple and pear varieties,” Brandle says. “We are having the kind of impact that we sought in those early days.”
Natural ways to control greenhouse pests – called biocontrols – are making a real difference to flower growers and a new technology that can identify genetic variants for traits in all plants has just been spun-off into a for-profit company.
“We’re creating a reputation and that alone is an achievement because we’re the new kid on the block,” he says. “We have a ton of good people with and around the organization and on our board who are making this happen.”Vineland is an important partner to the horticulture industry, according to Jan VanderHout, a greenhouse vegetable grower and Chair of the Ontario Fruit and Vegetable Growers’ Association.
“They are very good at asking us what we want and taking a whole value chain approach to research and innovation,” VanderHout says. “You need the right facilities and expertise and Vineland fills that need to the benefit of the industry as a whole.”
Looking to the future, both Brandle and VanderHout predict that cap and trade pressure and high energy costs will result in more work around energy use and carbon footprint reduction.And Vineland’s consumer-focused approaches will continue to drive new innovation, from high flavour greenhouse tomatoes to Ontario-grown apple varieties.
“We will further lever consumer-driven plant breeding and work with the intent around pleasing consumers and trying to understand what they want so we can build that into our selection criteria,” Brandle says.
Consumers increasingly savour the convenience and taste of seedless watermelons, said Xin Zhao, a UF Institute of Food and Agricultural Sciences associate professor of horticultural sciences and lead author of a new study examining rootstocks, flavour and texture of watermelons.
Many growers produce seedless cultivars because that’s what consumers want, and it’s important to maintain the fruit’s yield and taste, as seedless cultivars might be more susceptible to fusarium wilt, a major soil-borne disease issue in watermelon production, Zhao said.
For the study, UF/IFAS researchers grafted seedless watermelon onto squash rootstocks to ward off soil-borne diseases, such as fusarium wilt. In plant grafting, scientists call the upper part of the plant the scion, while the lower part is the rootstock. In the case of vegetable grafting, a grafted plant comes from joining a vigorous rootstock plant – often with resistance or tolerance to certain soil-borne pathogens – with a scion plant with desirable aboveground traits.
Grafting is a useful tool to manage soil-borne diseases, but in this study, researchers were concerned that if they grafted watermelon onto squash rootstocks, they might reduce its fruit quality and taste. Overall, study results showed no loss in taste and major fruit quality attributes, like total soluble solids and lycopene content, Zhao said. Consumers in UF taste panels confirmed the flavour remained largely consistent between grafted and non-grafted plant treatments under different production conditions.
Furthermore, said Zhao, compared with the non-grafted seedless watermelons, plants grafted onto the squash rootstocks exhibited a consistently higher level of flesh firmness.
“We are continuing our grafted watermelon research to optimize management of grafted watermelon production, maximize its full potential and seek answers to economic feasibility,” she said.
Still to come is a paper that specifically tells researchers whether they warded off fusarium wilt under high disease pressure, Zhao said. Grafting with selected rootstocks as a cultural practice is viewed as an integrated disease management tool in the toolbox for watermelon growers to consider when dealing with fusarium wilt “hot spots” in the field, she said. However, most squash rootstocks are generally more susceptible to root-knot nematodes, a potential challenge with using grafted plants. Other UF/IFAS researchers are tackling that issue.
The new UF/IFAS study is published in the Journal of the Science of Food and Agriculture.
Kerwin Bradley, director of commercial innovation for Simplot, says the company’s marketing strategy for new varieties is based on customer polls and identification of marketing channels. “We don’t plant potatoes, or give seed to growers, until we know that there is a place for them to sell them, so how quickly that develops depends on how quickly we develop routes to market for those potatoes,” he says.
“That way we ensure we keep the risk really low for everybody, especially the growers.”
The company has been talking to major Canadian retailers to “check the pulse” of their interest in the new potato, says Doug Cole, Simpot’s director of marketing and communications.
First generation lines of the Innate potato, which boast lower bruising and acrylamide, were approved by Health Canada and the Canadian Food Inspection Agency last spring. Second generation lines, which have late blight resistance and lower sugar levels for improved processing, have already been approved in the U.S., and Canadian approvals are expected later this year.

Canada’s potato gene bank, or Canadian Potato Genetic Resources, is part of an international commitment to global food security.
If disease or a natural disaster strikes and potato crops are devastated, researchers from anywhere in the world can turn to the gene bank to rebuild the stock.
Researchers can also call on the gene bank for resources to help them develop stronger, more disease-resistant and environmentally-resilient varieties.
"We preserve some potato varieties that are of unique value to northern latitude climates, varieties that are adapted to shorter seasons with longer daylight hours. Only certain star varieties are grown by the potato industry so in the interest of preserving genetic diversity, an important part of our role as gene bank curators is to back up our genetic resources," said Dr. Benoit Bizimungu, Gene Resources Curator, Agriculture and Agri-Food Canada
Unlike other gene banks that preserve seed-propagated crops like grains, the potato gene bank is made up of live tissue cultures or tubers which are perishable and require- constant maintenance.
Plantlets are grown in aseptic conditions in test tubes that are stored in temperature-controlled growth chambers for six to eight weeks at a time. The collection is then refreshed,continuously monitored and periodically tested for contaminations.
Microtubers, or tiny potatoes about the size of a raisin, are also produced in test-tubes and preserved for up to a year as a backup. A duplicate collection of microtubers is kept at AAFC's Saskatoon Research and Development Centre.
"It's well worth it," says Dr. Bizimungu of the work involved in conserving high-value potato genetic diversity. "There are many potato varieties that aren't grown today that have traits that are of current or future interest to researchers and educators. Preserving these varieties ensures valuable attributes, and even those with known susceptibility to certain diseases, are kept for the development of future, better varieties."
The collection is comprised of heritage varieties, modern Canadian-bred varieties, as well as strains known to show differential reactions to certain diseases and breeding lines with specific traits scientists are interested in studying.
In addition to Canadian varieties, the collection also includes varieties from the U.S., Peru and many European countries including Ireland, the Netherlands and Estonia.
Canadian Potato Genetic Resource is part of Plant Gene Resources Canada (PRGC). The mandate of PGRC is to acquire, preserve and evaluate the genetic diversity of crops and their wild relatives with focus on germplasm of economic importance or potential for Canada.
Innate potatoes bruise less and have less black spots than conventional potatoes.
Doug Cole, director of marketing and communications, said the company is holding off allowing commercial growth of Innate potatoes in Canada until there's a proven market for them. READ MORE
The move means that the J.R. Simplot Co.’s Russet Burbank, Ranger Russet and Atlantic potatoes could be planted in Maine fields at any time. These potatoes were created by adding genes from a wild potato plant and are designed to be resistant to late blight. READ MORE
Gallegly and his research partner, Mahfuz Rahman, released two new varieties of tomato.
The tomatoes, identified as West Virginia ’17A and West Virginia ’17B, were obtained by breeding the tomatoes known as the West Virginia ’63 and the Iron Lady.
Gallegly developed the W.Va. ’63 tomato in the 1960s as a tomato resistant to late blight, a plant disease usually caused by fungi. The Iron Lady tomato, developed by Martha Mutschler-Chu of Cornell University, also resists late blight but also Septoria lycopersici, a fungus that causes spotting on leaves.
Gallegly said the stink bug, specifically the marmorated stink bug, is the likely cause of Septoria increasing on tomatoes.
“We just crossed the two tomatoes and in the second generation in the field, we made selections for fruit type, yield, taste and so on,” Gallegly said. “So we came up with two new varieties.”
Through their evaluation, the two tomatoes should have a higher tolerance to Septoria leaf spot and better fruit quality.Tomatoes are a specialty of Gallegly, who turns 94 this month.
He came to the University in 1949 as an assistant professor and was hired to become the vegetable plant pathologist for the state.
He spent his first fall and winter at the university collecting varieties of tomatoes and potatoes. The next year, he planted varieties of the two vegetables and discovered late blight was severe that year. So much so that he had zero tomato yield.
“That told me I had to go to work on trying to control this disease,” he said.
After 13 years of screening the vegetables and research, he came up a new tomato in 1963 — the West Virginia ’63.
Gallegly officially retired from the University in 1986 but earned emeritus status and kept a presence at the college to continue research and teaching.
On March 24, the two new tomatoes were unveiled during the annual Potomac Division of the American Phytopathological Society meeting in Morgantown. READ MORE
Jessica Brady of OSF accepted the award on behalf of the company.
“Okanagan Specialty Fruits is proud to be a long-time supporter of Fruits and Veggies – More Matters, and we look forward to continuing this support in years to come,” she said. “OSF has always been committed to promoting produce consumption for all ages, and we look forward to our flagship products, nonbrowning Arctic apples, helping support healthy lifestyles.”
Recipients of the Fruits & Veggies – More Matters Industry Role Model awards are recognized for the ongoing support and promotion of the health based mission and messaging efforts associated with the program.
From adaptability to the processing market and high yields to disease resistance, these potential new varieties have it all. For the first time, the breeding program unveiled a multi-purpose red-skinned selection showing promise for processing as wedges, and as a traditional table potato. Breeders have also developed Russet selections that have a longer shelf life in cold storage while maintaining stable sugars, making them attractive new selections to French fry processors. These were among 15 new potato selections that AAFC’s breeding team unveiled this year.
The selections were narrowed down from more than 100,000 hybrid seedlings grown and tested and measured over six years in AAFC greenhouses, laboratories and fields across the country. The selections are the result of continuing technological advances that are allowing AAFC researchers to probe the complicated DNA of potatoes to identify genes and strands of DNA linked to favourable traits. This will lead to the development of germplasm with the potential for better yields, nutritional value and cooking and processing qualities.
The selections also featured disease and pest resistance that make them less demanding on the environment and offer alternative choices for organic growers. With each genetic marker that is identified, researchers are able to more quickly and accurately search through hundreds of different kinds of potatoes, including centuries-old heritage varieties and wild species, for potential breeding lines that will produce new hybrids with the desired traits.
At this point, there is no evidence that either of the two pathogens overwinter in the soil. The generally accepted length of survival time in the soil for these pathogens is one week to six months, climate dependent. Longer survival is possible on plant matter in the soil. With that, the source of the inoculum, and hence the source of the disease, is seed. Therefore, any best management practices efforts on Dickeya dianthicola or Pectobacterium wasabiae must start with the seed.
Select seed from farms where Dickeya dianthicola or Pectobacterium wasabiae have not been detected and seed marketed in previous years has not been associated with Dickeya dianthicola or Pectobacterium wasabiae.
Check North American Certified Seed Potato Health Certificates before purchasing seed and select seed that had not been increased on a farm associated with Dickeya dianthicola or Pectobacterium wasabiae.
Select seed with zero blackleg levels reported on the North American Certified Seed Potato Health Certificate.
Select seed that has been PCR tested by an independent laboratory and confirmed to be free of Dickeya dianthicola and Pectobacterium wasabiae.
Select seed from farms where a zero tolerance approach to Dickeya dianthicola and Pectobacterium wasabiae is being implemented.
Seed lots with field readings of blackleg present should have reports that suspect plant samples were taken for testing and found to be Dickeya dianthicola and Pectobacterium wasabiae free.
Avoid seed from fields where symptoms of Dickeya dianthicola or Pectobacterium wasabiae were observed, even if affected plants were rogued out.
Where possible, avoid irrigated seed crops.
Where possible, avoid planting whole-seed lots that were stripped from multiple lots.

Cold Spring Harbor, NY — Using a simple genetic method to tweak genes native to two popular varieties of tomato plants, a team at Cold Spring Harbor Laboratory (CSHL) has devised a rapid method to make them flower and produce ripe fruit more than two weeks faster than commercial breeders are currently able to do.
This means more plantings per growing season and thus higher yield. In this case, it also means that the plant can be grown in latitudes more northerly than currently possible – an important attribute as the earth’s climate warms.
“Our work is a compelling demonstration of the power of gene editing – CRISPR technology – to rapidly improve yield traits in crop breeding,” said CSHL Associate Professor Zachary Lippman, who led the research.
Applications can go far beyond the tomato family, he added, to include many major food crops like maize, soybean, and wheat that so much of the world depends upon.
Lippman clarified that the technique his team published in Nature Genetics is about more than simply increasing yield.
“It’s really about creating a genetic toolkit that enables growers and breeders in a single generation to tweak the timing of flower production and thus yield, to help adapt our best varieties to grow in parts of the world where they don’t currently thrive.”
At the heart of the method are insights obtained by Lippman and colleagues, including plant scientists at the Boyce Thompson Institute in Ithaca, NY, and in France led by Dr. José Jiménez-Gómez, about the evolution of the flowering process in many crops and their wild relatives as it relates to the length of the light period in a day. Genetic research revealed why today’s cultivated tomato plant is not very sensitive to this variable compared to wild relatives from South America. Somehow, it does not much matter to domesticated plants whether they have 12 hours of daylight or 16 hours; they flower at virtually the same point after planting.
A well-known hormonal system regulates flowering time – and hence the time when the plant will generate its first ripe fruit. The hormone florigen and a counteracting “anti-florigen” hormone called SP (for self pruning) act together, in yin-yang fashion, to, respectively, promote or delay flowering. In one phase of the newly reported research, the investigators studied a wild tomato species native to the Galapagos Islands – near the equator, with days and nights close to 12 hours year-round. They wanted to learn why, when grown in northern latitudes with very long summer days, this plant flowered very late in the season and produced few fruits.
The wild equatorial tomato, they learned, was extremely sensitive to daylight length. The longer the day, the longer the time to flowering, whereas “when you have a shorter light period, as in the plant’s native habitat, they flower faster,” Lippman said. This suggested there was a genetic change in tomato plants that occurred at some point before or during the domestication of wild tomato plants. Lippman suspected these changes likely had already occurred when the Spanish conquistador Cortez brought tomatoes to Europe from Mexico in the early 16th century, beginning the era of the plant’s widespread adoption in mid-northern latitudes.
Lippman and colleagues traced the loss of day-length sensitivity in domesticated tomatoes to mutations in a gene called SP5G (SELF PRUNING 5G). It’s a member of the same family of florigen and anti-florigen genes that were already known to regulate flowering time in tomato.
Growing the wild tomato plant from the Galapagos in greenhouses and fields in New York, Lippman and colleagues observed a sharp spike in the expression and activity of the anti-florigen hormone encoded by the SP5G gene, causing flowering to occur much later. In domesticated tomato plants, in contrast, that surge of anti-florigen is much weaker.
The team’s principal innovation – generating varieties of cherry and roma tomatoes that flower much earlier than the domesticated varieties on which they are based – arised from the observation that while domesticated plants are notably insensitive to day length, “there was some residual expression of the anti-florigen SP5G gene,” Lippman said.
This led the team to employ the gene-editing tool CRISPR to induce tiny mutations in the SP5G gene. The aim was to inactivate the gene entirely such that it did not generate any anti-florigen protein at all.
When this tweaked version of SP5G was introduced to popular roma and cherry tomato varieties, the plants flowered earlier, and thus made fruits that ripened earlier. Tweaking another anti-florigen gene that makes tomato plants grow in a dense, compact, shrub-like manner made the early flowering varieties even more compact and early yielding – a trait the team calls “double-determinate.”
“What we’ve demonstrated here is fast-forward breeding,” Lippman said. “Now we have a simple strategy to completely eliminate daylight sensitivity in elite inbred and hybrid plants that are already being cultivated. This could enable growers to expand their geographical range of cultivation, simply by using CRISPR to rapidly ‘adapt’ tomato and other crops to more northern latitudes, where summers have very long days and very short growing seasons.”
