GGE biplot analysis in finger millet [Eleusine coracana (L.) Gaertn.] genotypes across agro-climatic zones of Andhra Pradesh

The main focus of the study is to identify promising finger millet genotypes with yield stability and adaptability for wide range environments as well ideal mega-environments using genotype plus environment interaction (GGE) biplot method. Grain were remarkably influenced by (E), (G) their (G x E). was significant though comparatively less than location effects. has spotted best varieties suitable cultivation across five zones growing areas Andhra Pradesh. cultivar PPR-1152 recognized perfect it showed higher grain compared other cultivars in all places.
