摘要

Blackgram (Vigna mungo L.) is a self-pollinated short duration pulse crop, grown in all areas. However, its production is affected by Cercospora leaf spot (CLS), powdery mildew (PM) and yellow mosaic virus (YMV) leading to considerable yield losses.Three mutants (BM-63, BM-42 and BM-4) and one check variety (BARI Mash-3) were used in the field experiment with Randomized Completely Block (RCBD) Design. For CLS, BM-63 showed moderate resistance, whereas other two mutants BM-4 and BM-42 were moderately susceptible at all locations, while BARI Mash-3 was more vulnerable and exhibited the highest disease incidence rate 44.33%. For PM, all mutants BM-4, BM-42 and BM-63 revealed moderate resistance with lower incidence rate 23.54–29.36% compared to check variety BARI Mash-3 which was moderately susceptible with disease incidence 42.06%. In the case of YMV, BM-63 and BM-42 exhibited moderate susceptibility with the disease severity score 5 whereas BM-4 and BARI Mash-3 were susceptible with the severity score 7. In grain yield comparison, BM-63 and BM-42 mutants produced the highest yield in all locations. BM-63 produced 661.6 kg/ha, 794.2 kg/ha and 812.6 kg/ha in all respective locations, followed by BM-42 producing 804.4 kg/ha, 738.4 kg/ha and 751.3 kg/ha, respectively. The findings of this study indicate that BM-63 and BM-42 were found to be the most promising mutants for developing resistant blackgram varieties with a view to sustainable pulse production in Bangladesh.
