Stability analysis for seed cotton yield and its components of conventional, GMS and CMS based hybrids in upland cotton (Gossypium hirsutum L.)

Abstract

The present investigation was undertaken to study phenotypic stability of parents and hybrids. The experimental material consisted of nine parents (seven females and two males) and their forty two resultant crosses that were made in conventional (14), GMS (14) and CMS (14) system at three locations viz., Surat, Hansot and Bharuch. The Eberhart and Russell model (1966) of stability analysis was carried out to study the genotype x environment interaction for seed cotton yield and its component traits. The analysis revealed that environment component was considerably higher than genotypes and genotypes x environment component for all the characters. Looking to the overall performance in three methods, the parental line G(B) 20 was the most stable parent in seed cotton yield and the cross G(B) 20 x G.Cot.10 with desirable stability.
