Study of genotype x environment interactions and stability among diverse Gossypium arboreum L. genotypes for yield and related traits under North Western Plains

Abstract

The present investigation was undertaken with an objective to determine the effect of genotype × environment (GE) interactions and stability on Gossypium arboreum genotypes belonging to different part of country for seed cotton yield and related traits. 
Seventeen Asiatic cotton genotypes were evaluated in randomized block design at Ludhiana, for two years (2010 and 2011) and at Faridkot for one year (2010). The significant genotypes, environments, genotype × environment interactions were observed for all traits. Stability parameters revealed LD694 and LD902 were most stable and significantly outperforming for most of the traits except halo length where DLsa1001 was ahead. Genotypes developed at Punjab were found to be more stable for most of the traits whereas genotypes from other centers can be used as germplasm for pre-breeding programmes.
