Abstract
This study was conducted in two seasons (2020-2021) and (2021-2022). First year (45) single plants and (45) samples (variety) with three replications were studied which they collected from (45) bread wheat field farmers under rain-fed condition. In the second year (12) varieties planted in Randomized Complete Block Design (R.C.B.D.) by three replications in Directorate of Agriculture Research-Erbil. First year result showed that most lines had higher yield and yield components than the standard verities, and (L42) had outperformed than other lines. Second year results showed variety (Hewlir 4) had outperformed than all other varieties in most of the traits, it obtained high yield and thousand grain weight by (16.9 g and 30.9 g) respectively. There was high phenotypic and genotypic correlation between yield/plant and thousand grain weight, seed/spike, grain per plant, and harvest index. High heritability (98 and 97) and high expected genetic advance (57 and 39) found in yield/plant and thousand grain weight respectively
