Abstract

                                Eleven hybrids and one check variety of sunflower were evaluated for their stability of seed yield and five other metric traits in rainfed vertisol over years. The genotypes showed significant differences among them over environments and genotype x environment interaction was significant for all the characters viz, plant height, head diameter, number of leaves per plant, days to maturity and seed yield except days to 50% flowering. AH 1, AH 3, AH 4, AH 6, and AH 8 are desirable hybrids for adverse environments and head diameter and number of leaves can serve as useful selection indices.

Key words : Sunflower, Hybrids, Stability, Correlation, Regression
