Abstract:
Seven durum wheat genotypes were studied. The experiment was carried out using a randomized complete block design during 2015-2016 and 2016- 2017 to study the path coefficient analysis and the correlation between grain yield and its components. The genotypes that we used have good variation to be used as parents in the wheat hybridization program. Grain yield showed positive significant correlation with number of grains per plant (0.800**), thousand kernel weight (0.536**), biological yield (0.452) and the number of spikes per plant (0.423) was observed. Result of path coefficient analysis showed that the percentage of number of grains per plant was (66.26%), thousand kernel weight (36.36%), and number of spikes per plant (0.25%). That manes grain yield of wheat crop it using can be achieved by using number of grains per plant, thousand kernel weight, and number of spikes per plant.
Key words: genotypes, durum wheat, path coefficient, correlation, grain yield.
