Comparison of AMMI and GGE Biplot analysis to assess the adaptability and stability of Bt cotton genotypes

Development of high yielding, genetically stable Bt-cotton hybrid has been a priority in cotton breeding. Popular biometric tools such as AMMI and GGEbiplot 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...
