CRISPR genome-editing technology opens new opportunities to engineer disease resistance traits. ![]() However, the limited availability of resistant potato varieties and the rapid loss of R resistance, caused by P. Resistance gene (R)-based resistance to late blight is the most effective method to inhibit infection by the causal agent Phytophthora infestans. Plant diseases threaten food security and are expected to increase because of climate change. Late blight is considered the most renowned devastating potato disease worldwide. The latter will be released to industry to allow growers to evaluate them in real production conditions. To meet increasing global food demand, breeders and scientists aim to improve the yield and quality of major food crops. Once they’ve narrowed down the most promising candidates, they will continue to evaluate them against a long list of criteria in the hopes of identifying a superior combination of traits. Scientists are looking at lines combining multiple resistances and suitable end-use quality traits. Head potato breeder Benoit Bizimungu says more than 85,000 potential new potato varieties are being planted this year at Benton Ridge to help researchers identify superior selections for various markets.Īccording to AAFC, more than 57 per cent of the varieties being trialed incorporate resistance to late blight and/or PVY through the use of wild potato relative species, exotic cultivars and advanced germplasm from other breeding programs. Cara is a long-season potato variety that. Cara: Cara is a white potato ideal for either mashed or baked potatoes. The high resistance to Phytophthora (late blight) range currently consists of the varieties Alouette, Carolus, Levante, Nofy, Twinner, Twister, the still young. ![]() ![]() That’s why scientists are continuing to evaluate a large number of possible potato candidates with potential resistance to late blight and potato virus Y (PVY) - two of the most common threats potato farmers have to deal with every year. Floury Blight Resistant Potatoes Blue Danube: This is a mid to late-season potato prized as a baker, but is also good for frying or in salads. Planting season is underway at Agriculture and Agri-food Canada’s Benton Ridge substation near Woodstock, N.B., where scientists are putting potential new potato varieties through their paces in the hopes of identifying superior potato selections to meet industry and consumer needs.Īccording to AAFC, developing disease resistant potatoes is one of the main priorities of the Fredericton Research and Development Centre’s potato breeding program in order to help farmers protect production and reduce costs.
