Abstract

Stability analysis for thirty-three pearl millet genotypes and two checks was carried
out in three different environments during 2018-2019. G × E interaction was estimated using Eberhart
and Russell model and genotype-grouping method. The ANOVA revealed significant effect of
environments on the performance of hybrids for the three traits taken. Among the hybrids, AUBH-15
showed stable performance for grain yield per plant as it had high mean, non-significant deviation
from regression (S2di), regression around unity and low co-efficient of variation, hence, this hybrid
can be recommended for commercial cultivation. The hybrids which were identified as stable for
other attributing traits by regression model could not be confirmed by the grouping technique. Thus, the
recommendation was given based on the grain yield per plant, the most important economic trait. The
study must be extended to more diverse testing sites to obtain more robust information on the
environment effect.
