Abstract
Background: Blackgram is an important pulse crop consumed in the form of fermented cuisines especially in south India. Yield being a complex trait, is highly influenced by environment. Studies on environmental influence on batter quality are rare. Hence, the current study was taken up to identity stable genotypes over environments with respect to yield and batter quality traits.Methods: In the present study, 32 blackgram genotypes were evaluated for yield performance and batter quality traits during kharif 2019, rabi 2019-20 and summer 2020 at National Pulses Research Centre, Vamban. Pooled analysis of variance and stability analysis was performed by AMMI and GGE biplot.Result: From stability analysis, it was evident that the genotypes, ACM BG 17-001, ACM BG 17-006 and ACM BG 18-010 expressed high mean value and stability for seed yield. In case of idly batter volume, the genotypes, ACM BG 17-001 was stable hence may be recommended for all season cultivation. The trait, vada batter volume was found to be with non-significant GxE interaction and hence do not interact with the environment. Among the environments under study, summer season was the most favourable environment for seed yield. However, for idly batter quality, kharif season was the most favourable environment.
