HETEROSIS AND COMBINING ABILITY FOR YIELD AND ITS RELATED TRAITS IN BREAD WHEAT (Triticum aestivum..

In a line tester making pattern, seven bread wheat genotypes were crossed. During the 2018/2019 growing season, the 12 F1s and their parents were sown in a threereplication randomised complete block pattern at AlRashedia Farm in Ninevah, Iraq. The findings revealed that the traits had a high level of genetic variability. In comparison to the parents, the hybrid (Kirchanff Cam6) produced more grain and had a higher average yield portion. For number of grains per spike, grain yield, and 1,000 kernel weight, the Kukri line and Cham6 tester were a successful combiner. Negative substantial heterosis was observed for the studied traits in (Magenta Adnanea) and (Kirchanff Cham6). There was less genetic variance due to additive genetic variation.Both additive and nonadditive genes were supported by dominance variance for all traits followed by a low value of narrow sense heritability.
