Abstract
An experiment involving 50 genotypes of Finger millet (Eleusine coracana (L.) Gaertn)” was conducted in randomized block design with three replications, during Kharif 2021. Fifty finger millet genotypes were tested for four different environments viz., E1 and E2 at Student Research Farm, C.S.A.U.A.&T. Kanpur sown on 21 June, 2021 and 20 July, 2021 respectively and E3 and E4 sown at Research Farm, Daleep Nagar, Kanpur on 22 June, 2021 and 26 July, 2021respectively. The analysis of variance for pooled data revealed that the mean sum of square for genotypes and environments was highly significant against pooled error for all the characters except ear head width, ear head length and harvest index. The mean sum of square for genotypes against pooled error was highly significant for ear head length and harvest index; significant for ear head width. The mean sum of square for genotype × environment (G×E) was found highly significant for finger width while, significant for plant height, ear head weight and protein content. The overall performance of genotypes for grain yield per plant indicated that the genotypes IC0475654, IC0346263, IC0476359, IC0298482, IC0474862 and IC0475798 showed average stability while, for the protein content, the genotypes IC0347254, IC0474862, IC0475632 and IC0475457 showed average stability across all environments.
