In the present study, 14 sorghum genotypes comprising 12 advanced lines and two check varieties were evaluated for stability parameters over three locations during rabi 2022-23. Based on the six morphological and yield traits, pooled ANOVA showed significant differences for the quantitative traits. Meansum of squares due to E+ (G x E) was significant for all of the traits. Environment component showed significant values for all traits. The G x E (linear) showed significant interaction for all the traits in this study except days to 50% flowering. RSV-2657, RSV-2589 and RSV 2596 genotypes had mean value more than population mean, coefficient of regression near to unity and non-significant deviation from regression, hence adapted to all situations

Rabi Sorghum, G x E, grain yield, dry fodder yield

It is concluded that the genotype RSV 2657, RSV 2598 and RSV 2596 could be included in the hybridization program to converge the stability characteristics of grain yield for the development of stable cultivar adapted to a wide range of environments. These genotypes after further multilocation testing may be released as varieties for medium soil type of Maharashtra. Thus, any generalization regarding stability of genotypes for all characters it is too difficult since the genotypes may not simultaneously exhibit uniform responsiveness and stability for all the characters
