Genetic resource development for mungbean yellow mosaic virus (MYMV) resistance inmungbean [Vigna radiata (L.) Wilczek]

Abstract

Mungbean [Vigna radiata (L.) Wilczek] is an important short duration grain legume which is grown in differentparts of the country, for grain and green manure. It is an outstanding source of easily digestible proteins with low flatulence,which balances the staple rice diet in Asia. Mungbean yellow mosaic disease (MYMD) caused by whitefly (Bemisia tabaci)transmitted mungbean yellow mosaic virus (MYMV) is an important constraint of mungbean cultivation in India. Thecurrent investigation was taken up to develop MYMV resistant genotypes through pedigree method of breeding.Eighty-eight F3 progenies were evaluated for their reaction to MYMV under natural field conditions during summer2018-2019 with infector rows grown after every ten F3 progenies of test entries. On screening the F3 progenies for reactionto MYMV the percent disease incidence varied from 5 to 92.3%. The lines DGGV-200, DGGV-218, DGGV-281 andDGGV-284 were observed to be resistant and DGGV-198, DGGV-206, DGGV-212, DGGV-215, DGGV-226,DGGV-268and DGGV-282 were moderately resistant
