Stability of promising greengram (Vigna radiata (L.) Wilczek) genotypes over seasons through AMMI analysis
Abstract
Genotypes x environment interaction (GEI) effects are of special interest for plant breeders to identify stable genotypes. Present experiment was conducted for two years and two seasons from 2016-17 to 2017-18 at National Pulses Research Centre, TNAU, Vamban to assess the stability of 28 greengram genotypes for seed yield. In AMMI1 biplot for seed yield, the genotypes viz., VGG 16-003, VGG 16-016, VGG 16-054 and VGG 16-055 had IPCA 1 score close to zero with high main effects indicating that these genotypes were less influenced by environments and high yielders. VGG 16-054 and VGG 16-055 with high main effect and positive IPCA 1 score away from zero were identified as highly interacting genotypes with high yield. Genotypes viz., VGG 16-026, VGG 16-048, VGG 16-052, VGG 16-058, VBN (Gg) 3 and CO 8 were less interacting genotypes with high seed yield. These genotypes may be recommended for both the seasons viz., Kharif and Rabi seasons. Among environments, Kharif and Rabi seasons are highly interacting environments.
