Evaluation of Promising Mungbean Genotypes at Central Terai of Nepal

Abstract

: In order to select the superior genotypes for Nepal's central terai, sixteen mungbean varieties from the Grain Legume Research Program, Khajura, Banke, were tested at the Directorate of Agriculture Research, Parwanipur, Bara. In the years 2021 and 2022, an experiment with alpha lattice design and two replications were conducted on these genotypes. Plant height, number of pods per plant, seed per pod, 100 seed weight, flowering and maturity days from sowing, and yield ton per hectare (t/ha) were the parameters compared. Early maturation was observed in VC 1973A, VC 3890A, and VC 6148 during the two years of observation. In 2021, KPS # 1 produced the highest mean grain yield (0.50 t/ha), followed by CN 95 (0.42 t/ha), VC 3890A (0.41 t/ha), and Pant Mung 2 (0.40 t/ha). In contrast, in 2022, these genotypes' yields were 1.82 t/ha in KPS # 1, 1.79 t/ha in VC 3890A, 1.75 t/ha in Pant Mung 2, and 1.67 t/ha in CN 95. Due to the water-logged conditions brought on by heavy rainfall during the flowering to maturity period in 2021, the yield of test genotypes was low. The better genotypes may provide future varieties or serve as valuable genetic resources for breeding programs aimed at develop new varieties appropriate for Nepal's central terai.
