AMMI with BLUP analysis for stability assessment of wheat genotypes under multi locations timely sown trials in Central Zone of India

Ajay Verma* and GP Singh

AMMI analysis explained the highly significant effects of the environment, GxE interaction, and genotypes for wheat genotypes evaluated under restricted irriation timely sown multi-location trials in the Central zone of the country during 2018-19 and 2019-20. About 77.1%, 12.2% & 2.3% had been contributed by environments, interactions and genotypes of the total sum of squares due to treatments respectively in the first year. The utilization of more number of IPCA’s in AMMI and WAASB stability measures had altered the ranking of genotypes. Analytic measures of adaptability and Superiority indexes as per BLUP of genotypes identified DBW110, MP3288. Adaptability measures as per arithmetic, geometric and harmonic means and their corresponding values expressed deviation as observed in a seperate quadrant of Biplot graphical analysis. However, this group maintained the right angle with MASV, MASV1, and stability measures. The cluster of Superiority indexes as per averages yield of wheat genotypes placed in the adjacent quadrant. Superiority indexes favored HI8823, MP3288, DBW110 wheat genotypes for high yield and stable performance for the second year. Adaptability measures as per arithmetic, geometric and harmonic means along with the corresponding values of RPGV & MHRPGV expressed bondage and placed in a different quadrant. Cluster of Superiority indexes as per averages of the yield of wheat genotypes seen in the same quadrant as more than 73.5% variation accounted for by the first two principal components.
