Abstract

Article History -1 (g), dormancy (days), oil content (%) and protein content (%) except 100-pod weight (g), 100-kernel weight (g), sound mature kernel (%), shelling (%) and harvest index (%)indicating the influence of environmental conditions on the genotypes evaluated except for above five traits. The mean squares due to G×E (linear) were significant for days to 50% flowering, days to maturity, dry pod yield -1 (g), 100-kernel weight (g), sound mature kernel (%), shelling (%) and protein content (%). On further perusal of genotypes in relation to overall performance revealed that genotypes viz. AG-2008-7, AG-2008-9, ICGV-99181 and J-68 were found stable for unfavourable environments (b i <1 and high mean). These genotypes also exhibited stability for most of the yield contributing characters.
