ABSTRACT
Field experiments were undertaken to assess yield stability of some new okra-leaf cotton strains under a wide range of environments. Six okra-leaf upland cotton strains and two normal leaf check varieties, MNH-552 and FH-1000 were planted under six environments. Substantial differences were observed among genotypes for seed cotton yield and yield stability. Regression of seed cotton yield on the environmental index successfully depicted differences among the tested genotypes for yield stability. Okra-leaf genotypes, HR149-552 and HR170 exhibited unit regression coefficient and above average seed cotton yield. Genotypes, HR149-552 and HR170 appeared to be suitable for a wide range of environments. Although the standard normal leaf cultivar FH-1000 produced highest overall average yield, it was less stable across environments as compared to okra-leaf genotypes. Generally okra-leaf strains were better adapted to less conducive environments.
