Soybean is grown in Rabi crop as rainfed crop which express wide production gap due to wide environments. Therefore, development stable soybean varieties may minimize the production gap at high sustainable advantages. Stability explains why genotypes' average performance across a wide range of environments is an important characteristic in current breeding lines. Keeping the aforementioned factors in mind, the current study was carried out in randomized block design with three replications to examine 20 advanced breeding lines created as part of the All India Coordinated Research Project on Soybeans at RAK College of Agriculture, Sehore (M.P.). Under present investigation adoptive potential and relative stability of 30 genotypes of soybean for yield and its contributing traits have been determined. The pooled analysis of variance carried out to know the response of different characters. To various environmental factors, revealed that genotype × environment interactions were significant for number of primary branches per plant, plant height, number of pods per plant, biological yield per plant, number of seeds per plant, seed yield per plant and 100 seed weight. This suggested that these characters were highly sensitive to the changes in the environmental conditions. Whereas interactions for days to 50% flowering, days to maturity and harvest index were non-significant which indicated that these traits and show least effect to the changes in the environmental conditions.

Variability, heredity, genetic advancement, stability, association

Stability performance furnished information about the adaptation of genotypes in different environments. Genotypes, RVS2012-6 and RVS2012-5 Showed stability for major yield and yield components and could be recommended for cultivation in western part of the Vindhyan Plateau of Madhya Pradesh during Rabi season. The traits viz., days to maturity, plant height, number of branches per plant and pods per plant have been identified as major yield contributing traits through association analysis. High estimates of heritability accompanished by high genetic advance were recorded for plant height, number of pods per plant, number of seeds per plant over environments suggested that direct selection on these traits can improved the seed yield.
