Stability analysis for seed yield and its attributing traits in advanced breeding lines of blackgram [Vigna mungo (L.) Hepper]

Abstract

Blackgram plays a significant role in Indian food as a supplement to cereal based diet. It contains three times higher protein than cereals. In India, unavailability of stable and high yielding varieties is a major issue in blackgram. Yield is a quantitative character and is significantly influenced by environment. A study was carried out with 18 genotypes during kharif season (2021) at four locations (Sehore, Gwalior, Barwani and Jhabua) to determine stable genotypes of blackgram by Eberhart and Russell approach for 12 yield and its attributing traits. The genotypes RVSU 22-6, RVSU 22-8, RVSU 22-12, Indira URD 1 (C) and IU 94-1 were found to be most stable and adapted to the diverse environments and could be included in the hybridization program to converge the stability characteristics of grain yield for the development of stable cultivar adapted to a wide range of environments.
