Abstract: The present investigation was carried out to study stability performance over three environments for seed yield and contributing characters in 38 genetically diverse genotypes of kabuli chickpea. Pooled analysis of variance revealed significant mean square estimates due to genotypes for all the characters included for stability analysis. The significance of genotype x environment interaction for all the traits except seeds per pod and protein content revealed differential response of the genotype to varying dates of sowing. This suggested the importance of testing the material over different environmental conditions. Mean squares due to linear and non-linear components of genotype x environment interaction were significant for all the characters. This showed that genotypes possessed differences for linear response to varying environments as well as for deviation from regression for all the traits. Thus, prediction for these traits was difficult. Eight genotypes viz., KAK 2, BG 2084, NDGK 902, HK 04-178, JSC 51, BG 2082, ICCV 6301 and ICCV 7310 possessed higher mean than population mean coupled with non-significant regression coefficient and deviation from regression, hence, above said genotypes may be considered as ideal. The yield stability of different genotypes has been discussed in relation to their stability for yield contributing characters.
For further improvement, it was suggested to adopt appropriate selection procedure for yield and yield components like days to flowering, number of branches per plant, number of pods per plant, biological yield per plant and 100-seed weight.
