| Summary: | The study was conducted at AICRP on Soybean, Zonal Agricultural Research Station, UAS, GKVK, Bengaluru, to detect and quantify the stable performing genotypes by temporal environment interaction. Fifty-eight genetically stable soybean lines selected from F5 population of four crosses were evaluated with two checks in α-lattice design with two replications, across three dates of sowing namely, 20thJanuary, 20th February and 20th March during, 2022. Pooled ANOVA revealed a significant difference for number of pods plant-1 and grain yield plant-1 attributable to genotypes × dates of sowing. The AMMI ANOVA indicated a significant difference attributable to GEI for number of pods plant-1, and grain yield-1. Based on the lower estimates of AMMI stability value and stability index for grain yield plant-1 lines 3, 23, 8, 5 and 14 in cross JS24-34 × RVS2001-18, 10, 3, 7 and 2 lines in cross JS20-34 × RVS2001-18, lines 9, 10, 6 and 8 in cross DSb-31 × MACS1460 and lines 12, 5, 1, 8 and 4 in cross DSb-21 × EC457254 were regarded as widely adaptable and stable genotypes.
