Heterosis for Yield, Yield Components and Nutritional Traits in Mung Bean (Vigna radiata (L.) Wilczek)

Twenty mungbean hybrids were derived five lines, four testers, through linex tester mating design were evaluated to study the magnitude of relative heterosis, heterobeltiosis and standard heterosis for yield and nutritional traits. The magnitude of relative heterosis, heterobeltiosis and standard heterosis observed for seed yield per plant were 57.45, 53.67, and 51.04 respectively. Heterosis for seed yield per plant is manifested through heterotic response for most of the yield contributing traits in additive fashion. The crosses LGG-574 x Pusa Vishal, LGG-574 x PM-5, LGG-460 x Pusa Vishal, LGG-460 x IPM-2-14 and LGG-407 x PM-5were adjudged as superior heterotic crosses for seed yield, yield components and nutritional traits. Therefore, these crosses could be exploited by adopting recurrent selection or biparental mating mating to derive high yielding segregants in mungbean.
