Abstract:

Development of high yielding, genetically stable Bt-cotton hybrid has been a priority in cotton breeding. Popular biometric tools such as AMMI and GGE-biplot analyses were compared to identify the stability of cotton hybrids for seed cotton yield across three locations in India. Both models showed significant variances for seed cotton yield due to genotypes (G), environment (E ) and GE interaction The AMMI model treated three environments (Aurangabad, Raichur and Dharwad) as very distinguishing by, whereas the GGE-biplot considered them as two mega environments (ME) with Aurangabad and Raichur as similar. Stable hybrids identified from both the statistical biometric tools were also differing. The AMMI analysis indicated that IAHH-8102 BGI, IAHH-8006 BGII and IAHH-8005 BGII were found to be promising hybrids, whereas IAHH-8039 BGI, IAHH-8041BGI and IAHH-8046 BGII found to be stable in GGE analysis. Although both methods efficiently diagnosed the interaction and stability, GGE Biplot was more user-friendly approach in identification of hybrids without compromising the yield parameters.
