 The experiments were taken up at three different dates of sowing of the year 2010- 2011 viz. two summer season dates i.e., 3rd February and 23rd February (E1, E2) and one kharif season date i.e., 1st June (E3) for stability analysis on 58 Spanish bunch groundnut genotypes for 16 plant characters. The material was evaluated in randomized block design with three replications at Anand Agricultural University, Anand. The mean squares due to genotype×environment (G×E) interactions were significant for the characters; days to 50% flowering, number of primary branches-1, days to maturity, plant height (cm), number of mature pods-1, dry pod yield-1 (g), kernel yield-1 (g), haulm yield-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 (bi<1 and high mean). These genotypes also exhibited stability for most of the yield contributing characters.
