Stability analysis of seed cotton yield and its components in cotton (Gossypium hirsutum L.)

摘要

Thirty-two genotypes of cotton (Gossypium hirsutum L.) were sown under April and May sown conditions during 2004-05 and 2005-06 to study the phenotypic stability. Mean square due to genotype, environment and G x E interaction was significant for all the characters studied. Both linear and non-linear components of G x E interaction were significant. However, linear portion of G x E was higher than nonlinear. Considering stability parameters, six genotypes, namely, H-1226, H-1242, H-1287, H-1259, H-1300 and H-1316 were found ideal for seed cotton yield. Among them H-1287, H-1259, H-1300 and H-1316 were also found stable for most of the seed cotton yield contributing traits.
