Effect of Genotype by Environment Interactions on Quality Traits of Bread Wheat in Ethiopia (original) (raw)

HAL (Le Centre pour la Communication Scientifique Directe), 2021

Abstract

The presence of genotype by environment interaction complicates selection of superior genotypes. The study was conducted to evaluate the effect of GEI and its magnitude on the grain quality of bread wheat genotypes in Ethiopia. 15 bread wheat genotypes were evaluated using RCBD with 4 replications at 6 different locations in Ethiopia. Analysis of variance showed highly significant (P<0.001) differences among genotype, environment and its interactions for investigated quality properties. The results showed that the genotype ETBW9045 had excellent HLW followed by ETBW8070 (73.38 kg/hl) and ETBW8065 (73.02 kg/hl), while the lowest mean values of HLW was obtained from genotype ETBW9464 (66.58 kg/hl) and genotype ETBW9470 had excellent TKW followed by ETBW8427 (39.22 g), while the lowest was that of ETBW8075 (27.32 g). The mean value of moisture content of wheat genotype was ranged from 10.5% to 10.99%. In this result protein content varied from 13.93 to 15.05%. Genotype ETBW8065, ETB...
