Wheat genotypes as assessed by Additive main & multiplicative interactions (AMMI) and Best linear unbiased prediction (BLUP) for stability analysis under rainfed timely sown trials in Northern Hills Zone of India

Stability analysis of wheat genotypes under rainfed timely sown trials in Northern Hills Zone India by Additive main & multiplicative interactions (AMMI) observed highly significant effects the environment, GxE interaction and during 2018-19 2019-20. The ranking had altered with utilization more number IPCA’s AMMI WAASB measures. Environments contributed about 53%, accounted for 30.5% Genotypes explained only 5.4% total sum squares due to treatments first year. Wheat HS668, VL2035, VL2036 , HS562 been selected Analytic measures adaptability Superiority indexes. Different quadrants comprised a cluster arithmetic, geometric, harmonic means along corresponding Indexes considering averages grouped separately. This group maintained right angles MASV MASV1 Clustering Adaptability as per geometric placed quadrant. Second-year reflected VL2041, HS675, HS676 HS562, HPW471 superiority About 68% variation 38.4% 30.2% contributions PC1 PC2. angle other stability measures, exception There is an additional advantage these assign variable weights yield goal breeding trials. These indexes have potential provide reliable estimates future studies they are considered biplots.
