Assessment of Genetic Stability in Chickpea Varieties Through GGE and AMMI Analyses

Background: Chickpea is grown in diverse agro-climatic conditions and various varieties respond differently to these environments. Stability analysis identifies adaptable varieties that yield consistently across regions. Our study focuses on identifying high-yield, reliable chickpea varieties through extensive multi-environment trials Methods: To accomplish our research goal, we conducted a comprehensive stability analysis during 2020-21 and 2021-22 using 12 different methods which include parametric, non-parametric and PCA-based AMMI, GGE biplot analysis. This extensive analysis was applied to six distinct Chickpea varieties cultivated in three diverse environments. Result: CSJ515 consistently demonstrated stability in all 10 analyses, while GNG2144 and RSG959 showed stability in 7 analyses. GNG1958 exhibited stability in four analyses and GNG2171 and RSG974 were stable in 3 and 2 analyses, respectively. These results suggest that CSJ515, GNG2144 and RSG959 have broad and stable adaptability across diverse environments.
