The experiment was conducted to evaluate disease resistant mutants against foot and root rot, Cercospora leaf spot and mung bean yellow mosaic disease under natural epiphytotic condition, 9 mutants collecting from the Bangladesh Institute of Nuclear Agriculture were used in this experiment. Among the mutants, MBM-07(S)-2 was found resistant against the foot and root rot disease followed by MBM-347-13, MBM-390-94-Y and MBM-656-51-2. Most of all plants of each plot were attacked by Cercospora leaf spot of mung bean. The highest yellow mosaic disease incidence 84.76% was recorded in MBM-80 (LCAL) and the lowest 20.00% in MBM-527-114 followed by MBM-07-Y-2 (30.00%) and MBM-427-87-3 (33.67%). The highest yellow mosaic disease severity 26.84% was observed in MBM-80 (LCAL) and the lowest 0.38% was observed in MBM-527-114 followed by MBM-656-51-2 (1.04%) and MBM-427-87-3 (1.63%). The highest number of seeds per pod was counted in MBM-07-Y-1 and the highest 1000 seed weight was observed in BARI Moog-6 (50.00 gm) followed by MBM-527-114 (45.67 gm). The highest grain yield 204.44 kg was recorded in MBM-07-Y-1 followed by MBM-390-94-Y (186.66 kg). MBM-07(S)-2, MBM-07-Y-2, MBM-07-Y-1 and MBM-527-114 mutants showed less disease incidence and severity for foot and root rot, Cercospora leaf spot and mung bean mosaic disease and gave better yield than other mutants.
