Abstract:

The Present investigation was carried out to evaluate 42 sunflower hybrids, their parents involving seven cytoplasmic male sterile lines and six restorer lines along with three checks for their stability across three different locations of Telangana during Rabi, 2008-09. Pooled analysis revealed that significant differences between genotypes and environments. Highly significant genotype × environment interaction for all the characters studied. The variance due to environment (linear) was highly significant for all the characters. The variance due to pooled deviations (non-linear) was significant for all the characters except head diameter revealing fluctuating performances of genotypes from linearity of response to varying environments. Based on stability performance three hybrids viz., CMS 17A × LTRR 341, ARM 243A × 3376R and ARM 238A × 3376R were identified as stable for seed yield and other traits, hence suitable for wider environments. Two hybrids, CMS 234A × RHA-6D-1R and CMS 852A × RHA-6D-1R were found suitable for favourable environments.
