Genotype × Environment Interaction and Selection of High Yielding Wheat Genotypes for Different Wheat-growing Areas of Ethiopia

Evaluation of wheat genotypes under different environments is essential for testing stability their performance and range adaptations. Where, enhanced grain yield has been achieved in bread (Tritium aestivum L.) through the development adaptable, high-yielding, rust-resistant by evaluating advanced multi-environment trials. The adaptability a genotype over diverse usually tested degree its interaction with which it grown. This study examines fifteen two consecutive years (2016 2017) across eight locations Ethiopia. experiment was laid out using Randomized Complete Block design replicated three times intending to determine high-yielding release best performing as variety end-user. Highly significant (P ≤ 0.001) effects genotype, environment, environment were observed yield. AMMI analysis variance indicated that accounted 52.34% total sum squares (genotype yields ranged from 5.76 t/ha at E-11 1.31 E-7). followed (22.95%) (11.31%).The ETBW8260 (G4) exhibited high mean well performed environments. selected early maturing, yielding, resistant yellow rust fitting low midland growing areas advantage standard Ogolcho local Kakaba. Both are dispersed widely all quadrants AMMI-1 biplot. As per YSI (#15) ETBW8303 (G2), ETBW8454 (G12), ETBW8261 (G5), ETBW8406 (G10), ETBW8310 (G3), (G4), stable. Besides, (G4 highest good stability. Therefore, after one-year verification trial, released commercial 2019 designated name called “Balcha” recommended low-medium part production agroecology country.
