Abstract: An experiment was carried out involving thirty five sorghum genotypes including hybrid parents (maintainer and restores) hybrids and varieties during rabi season 2006-07 at six different dates of sowing to assess the stability of genotypes for seed setting behaviour and other productivity traits and to know the magnitude of variability present. The genotypes were also assessed for change in the nature of inter-relationship and path effects of different characters towards grain yield. Mean performance of genotypes indicated that 3rd date (5th October 2006) is the ideal environment for better expression of most of the characters. Analysis of variance revealed significant difference among most of the characters suggesting a high degree of variability among the genotypes tested. Genetic variability analysis revealed that plant height, panicle weight, grain yield per plant had higher heritability and expected GAM as compared to other traits. The pooled analysis of variance revealed significant difference among the genotypes and environments for all the characters, indicating that genotypes and environments tested are diverse in nature. Genotype × environment interaction was significant for most of the characters suggesting, genotypes interacted significantly with environments. On the basis of stability parameters, DSH-4 and M35-1 were promising genotypes for majority of the characters with higher mean performance across all the six dates of sowing. The association analysis revealed that number of primaries per panicle, seed set percentage and number of seeds per panicle had significant positive association with grain yield per plant in all the dates of sowing and path analysis indicated that 500 seed weight and number of seeds per panicle exerted high direct effect in all dates of sowing
