Technical Abstract: Beet curly top virus (BCTV) is a devastating disease of common bean in the Western U.S. Genetic resistance provides effective control but can be difficult to discern in early generations. G122, an Andean landrace from India, known as Jatu Rong, appears to possess resistance independent of Bct-1 gene as determined by allelism tests. Preliminary genetic analysis of 98 F5:7 RILs (G122/Taylor Horticulture) reveals a single QTL with major effect (34%) across multiple environments. The results indicate that G122 can be used in breeding programs to further enhance bean germplasm with additional resistance to BCTV.
