Exploration of Grain Yield Stability of Advanced Chickpea Strains Across Environments

Chickpea (Cicer Arietinum L.) Genotypes’ Assessment Through Diverse Environments

“…The biplot for the environment view, formed by plotting the vectors, detected favorable environments (Figure 2). The length of vectors and their respective angles to the average environment axis (AEA) abscissa specifies the power of environments (Yan et al, 2001;Yaghotipoor and Farshadfar, 2007;Rad et al, 2013;Usharani and Kumar, 2016;Mahmood et al, 2021). Based on the length of vectors, there were three main types of environments.…”

“…Chickpea (Cicer arietinum L.) occupies an eminent place in the farming system of Pakistan (Akhtar et al, 2021). Overstating its importance is unlikely due to its primary role in sustaining food security, generating revenue, and balancing the ecosystem (Jan et al, 2020;Mahmood et al, 2021). Chickpea is a major pulse crop and a rich source of proteins commonly called poor man's meat; therefore, it is crucial for food security (Merga and Haji, 2019).…”

“…It means that the performance of a genotype can fluctuate from one environment to another in such a way that a genotype superior in one environment may not be as much in another due to differing genotype interaction with the environment (G×E) (Makumbi et al, 2015). In detecting the most stable and betterperforming genotypes, several former researchers have extensively employed the GGE biplot and mega-environment analysis (Yan et al, 2000;Abbas et al, 2008;Gauch et al, 2008;Farshadfar et al, 2012 andMahmood et al, 2021). GGE biplot and megaenvironment models have proven the most effective analysis methods for evaluating genotypes under multi-environments for further genetic improvement programs (Samonte et al, 2005;Kaloki et al, 2019).…”
