Executive Summary : | Common bean, a major commercial pulse crop in the north-western Himalayan region of India, is known for its high quality and flavor. It is cultivated both as dry and snap bean, mainly by small and marginal hill farmers in Himachal Pradesh, Jammu & Kashmir, and Uttarakhand. Common bean productivity is affected by various factors, including disease caused by fungi, bacteria, and viruses, which reduce yield levels both quantitatively and qualitatively. The most common and destructive viruses infecting Common beans are Bean common mosaic virus (BCMV) and Bean common mosaic necrotic virus (BCMNV). Most cultivars grown in the region are susceptible to one or both viruses and their strains. Despite the reported resistance against viral diseases in India, there is little information on the genes and genomic regions imparting resistance against these viruses. Further studies are needed to determine if the resistance genes present in the North Western Himalayan beans are the same or different. To make meaningful progress in breeding BCMV/BCMNV resistance in India, additional sources of resistance and new tools and techniques are needed. Classical bi-parental mapping approach will be time-consuming to elucidate resistance genes in the Indian germplasm. Association mapping, which exploits historical recombination events at the population level, has become a powerful alternative to linkage mapping in dissecting complex trait variation at the sequence level. Genome-wide association (GWA) mapping, a complementary strategy for classical bi-parental linkage mapping, has been used successfully in Arabidopsis, rice, and maize. |
