Factors controlling qualitative and quantitative agronomic traits were mapped using DNA markers. Traits studied include: Resistance to late blight, tuber soft rot, wart disease, root cyst nematodes and PVX, tuber yield and tuber starch content, cold sweetening. Candidate genes for these traits were also mapped: Pathogenesis related genes, genes with similarity to known plant genes for resistance, genes involved in carbohydrate metabolism and transport.Integrating positional information of qualitative and quantitative resistance traits and candidate genes reveals hot spots for disease resistance genes in potato.
