BREEDING HIGH YIELDING AND DISEASE RESISTANT MUNGBEAN (VIGNA RADIATA (L.) WILCZEK) GENOTYPES
GUL SANAT SHAH KHATTAK , IQBAL SAEED AND SYED ANWAR SHAH
Abstract: Genetic variability was created for seed yield and its components in mungbean through hybridization by using local and exotic germplasm and through induced mutations only in local germplasm during summer and kharif 2004, respectively. The stable and high yielding genotypes developed through selections from the segregating populations were screened for Mungbean Yellow Mosaic Virus (MYMV) during kharif 2006 and evaluated in replicated yield trials for seed yield and some important agronomic traits at NIFA, Peshawar during summer 2007. The mutants/recombinants with significantly higher seed yield than check variety showed seed yield of 2250 to 3042 kg ha-1. The 1000 seed weight, days to flowering and physiological maturity of all the evaluated mutants/recombinants ranged from 39 to 51g, 40 to 49 days and 79 to 84 days, respectively. The MYMV rating of the mutants/recombinants was from resistant to highly resistant.
