Genetic Path Analysis and Correlation Studies of Yield and Its Components of Some Bread Wheat Varieties

Abstract The research was applied in one of the farmers’ fields Al-Khalidiyah / Anbar Governorate to determine most appropriate traits improve yield wheat grains during two seasons 2017-2018 and 2018-2019. experiment carried out according randomized complete block design with three replicates, aim studying path coefficient its components for seven varieties bread (IPA 99, Buhooth 85, Iraq, Abu Ghraib 3, Tamoz 2, Sham 6, Al-Rasheed). Most showed a significant positive correlation grain yield. Also, results analysis genetic indicated that indirect effect number total tillers on individual plant through productive tillers, 0.729 0.805 respectively, very close direct 0.887, 0.920. weight 1000 0.514, 0.707, negative tillers. Likewise, harvest index study recommends focusing breeding improvement programs characteristics grains, is best selection cereal due high impact
