GGE biplot analysis of finger millet (Eleusine coracana) genotypes under diverse agro-climatic conditions of Uttarakhand

Finger millet [Eleusine coracana (L.) Gaertn] is mostly cultivated in the arid and semi-arid regions of India. In this study, 11 finger genotypes were evaluated for six traits a randomized complete block design with three replications at Ranichauri (E1), Dehradun (E2) Pantnagar (E3) Uttarakhand during kharif 2018 2019. The analysis variance revealed significant variation among due to (G), environments (E) G×E interaction (GEI) effects. environment contributed 37.3%, 38.6%, 58.2%, 65.5%, 21.0% 76.9% total days 50% flowering, plant height, number tillers, heads, fingers grain yield, respectively. Grain yield exhibited crossover-type GEI effect high environmental proportion. mean over locations was ranged from 16.9 (E1) 38.8 q/ha (E3), whereas genotypic stretched 22.7 (PF5) 34.3 (PF8). GGE biplot graphical identified mega environments, best PF5, PF6 PF2 E1; PF8 E2; PF10 PF11 E3. Based on hypothetical ideal genotype, as genotype owing stability locations. ranking based would be follows: PF8>PF10>PF3>PF7>PF2>PF1>PF11>PF4>PF9>PF6>PF5. location had discriminating ability representativeness considered selecting high-yielding stable
