Evaluation of mungbean cultures against MYMV in Karnataka under natural conditions.
A large number of genotypes including some germplasm, breeding lines in F1 and F2 generations and some released varieties were evaluated against yellow mosaic virus disease of mungbean during rabi summer of 2004 and 2005. The results indicated that two genotypes GG-89 and GG-39 appeared to be immune with no disease incidence during 2004. The genotypes, TM-98-50, TM-97-55 and Co-5 showed resistant reaction against MYMV with disease incidence of 0.97, 0.87 and 0.58 percent during rabi summer 2005. Genotypes which showed resistant reaction could be used in MYMV disease resistant breeding programme after their confirmation.
