Varieties of the future: Identification of ‘broad spectrum’ genetic resistance in sugar beet [Full subscriber]

Sugar beet cultivars worldwide are susceptible to a wide range of pathogens and, with limited genetic host resistance available, the industry remains reliant on fungicide and insecticide treatments. Novel forms of genetic resistance to these pathogens are therefore highly sought. Our consortium has harnessed genetic diversity, from both wild and cultivated Beta germplasm, to identify novel genetic resistance to both viral and fungal pathogens. This study has employed a Quantitative Trait Locus (QTL) mapping approach to identify novel plant resistance (R) loci to foliar diseases such as Beet mild yellowing virus (BMYV), Erysiphe betae (powdery mildew) and Uromyces betae (rust)…
