Abstract

 One hundred bread wheat genotypes were grown at Holetta Agricultural Research center main station during main cropping season 2021-2022. Those genotypes were evaluated for variability parameters and correlation for grain yield per hector, grain filling period, and total number of tillers per plant, 1000-kernel weight, and kernel per spike. All traits shown significant genotypic differences. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were high for grain yield, thousand kernel weight and kernel per spike. This indicates that selection will be effective based on these traits and their phenotypic expression would be a good indicator of the genotypic potential of the studied wheat materials. All the studied characters recorded its heritability. These traits also indicate high expected genetic advance except grain filling period. Grain yield per plant showed highly significant positive correlation with thousand kernel weight, spikelet per spike, kernel per spike, and significant negative correlation with total number of tiller per plant. Based on quantitative data, bread wheat genotypes were grouped by cluster analysis on the basis of Euclidean distances of similarity to their distinct groups.
