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

Screening genotypes based on grain yield stability in different ecological zones is a prerequisite for developing a widely adapted genotype.For this purpose, 16 chickpea desi genotypes' evaluation through cooperative yield trial commenced during 2019-2020 at nine diversified locations across Punjab, Pakistan.Data underwent genotype by environment interaction (G × E) and mega environment analysis.Genotype plus genotype × environment (GGE) biplot view for yield depicted that G-4 (CH-21/13) was the ideal and superior genotype for stability and yield potential.GGE biplot 'what-won-where' for yield formed an irregular polygon showing interconnection among G-3 (CH-2016), G-4 (CH-21/13), G-8 (D-17003), G-11(D-17019), G-13 (TG-1427), G-14 (TG-1430), and G-16 (TG-1510), indicating these genotypes were comparatively more stable.Graphical representation of the mega environment analysis illustrated that E-1 (Pulses Research Institute, AARI, Faisalabad, Pakistan) was ideal and most discriminating for genotype screening.Results also revealed that the first mega environment's construction included the grouping of E-
