Abstract

Bread wheat (Triticum aestivum L.) is a self-pollinated annual crop belonging to the family (Poaceae), tribe (Triticeae) and genus Triticum. This study aimed to assess the magnitude of genotypic and phenotypic association among traits, and identify promising bread wheat genotypes for further breeding. A total of 100 bread wheat genotypes were evaluated in alpha-lattice design with two replications in the 2022 main cropping season at Liban Jawi District, West Shewa Ethiopia. The results of correlation analysis revealed that grain yield had a positive and significant correlation with spike length, kernels per spike, biomass yield, harvest index, thousand seed weight, productive tillers, and awn length; while negative significant correlation with days to 50% heading, days to 90% maturity and non-significant correlation with grain filling period, plant height, spikelet per spike, flag leaf length, flag leaf width and peduncle length at genotypic level whereas positive and significant correlation with kernels per spike, biomass yield, harvest index, thousand seed weight, productive tillers, awn length, negative significant correlation for days to heading and non-significant for the left traits at phenotypic level.
