Abstract :Moth bean [Vigna aconitifolia insert ignore into journalissuearticles values(Jacq.); Marechal] susceptibility to yellow mosaic virus insert ignore into journalissuearticles values(YMV); purged the crop from the farming system. Therefore, genotype-by-environment interaction insert ignore into journalissuearticles values(GEI); and biplot studies were undertaken to develop YMV-resistant moth bean cultivars from the germplasm. The germplasm was acquired from the National Agricultural Research Centre insert ignore into journalissuearticles values(NARC);, Islamabad and from the farm fields in two provinces, Punjab and Sindh, Pakistan. Two different groups of moth bean genotypes were screened for YMV versus seed yield insert ignore into journalissuearticles values(11 genotypes); and YMV versus fodder yield insert ignore into journalissuearticles values(10 genotypes); over three years insert ignore into journalissuearticles values(2006-2008); in three locations in Pakistan [D.I.Khan Agriculture Research Station insert ignore into journalissuearticles values(ARS);, Serai Naurang ARS, and Karak ARS]. In all germplasm, four moth bean lines were identified as highly resistant to YMV with maximum grain insert ignore into journalissuearticles values(013393-C, 013388); and fodder insert ignore into journalissuearticles values(DMB-118-E, DMB-118-A); yields across all years and locations. Genotype, environment, GEI, and biplot analysis revealed that two moth bean lines insert ignore into journalissuearticles values(013393-C and DMB-118-E); showed the lowest YMV scoring insert ignore into journalissuearticles values(1); and maximum grain insert ignore into journalissuearticles values(33.40, 29.70, and 33.98 g plant-1); and fodder yields insert ignore into journalissuearticles values(15.30, 17.40, and 15.35 t ha-1); compared with susceptible checks, respectively. Keeping in view the genetic potential of YMV-resistance and the high grain and fodder yields of two moth bean lines insert ignore into journalissuearticles values(013393-C, DMB-118-E);, the Provincial Seed Council insert ignore into journalissuearticles values(PSC); of Khyber Pakhtunkhwa, Pakistan approved the two lines with the highest grain and fodder yields as new moth bean cultivars, naming them Dera Moth and Green Moth, respectively.
