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

Abstract

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.

Studies on Heterosis for Pod Yield and Protein Content in Yardlong Bean (Vigna unguiculata (L.) Walp. ssp. Sesquipedalis Verdc.)

“…Four hybrids were significantly superior by exhibiting significant positive heterosis over check Arka Mangala. These results are in conformity with the findings of Kalpana et al [2] and Kakde et al [3] in mung bean. Seven hybrids expressed significant positive relative heterosis.…”

“…Seven, one and eight hybrids were significantly superior by exhibiting significant positive heterosis over mid, better parents and Arka Mangala respectively for the character number of seeds per pod. These results are in conformity with the findings of Kalpana et al [2] and Kakde et al [3] in mung bean. Seventeen, nine and seven hybrids exhibited significant positive heterosis for 100 seed weight over mid parent, better parent and Arka Mangala (check) respectively.…”

“…The results are in conformity with earlier reports of Kumar et al [17] in pea. For protein content, Three, one and two hybrids significantly recorded high heterosis over mid, better parents and Arka Mangala respectively The superiority of this trait also was observed by Anitha et al [18], Srivastava and Singh [19] and Joshiet al [15] in cowpea, Kalpana [2] and Kakde et al [3] in mung bean (Table-5).…”
