Abstract\u00a0 \u00a0<\/strong><\/span><\/p>\n

The study was carried out during 2018\/2019 season in\u00a0 two locations, first at AL-sfira zone B (rainfed) and Hmayma location zone C (irrigated) \u00a0belong to Scientific Agriculture Research Center in Aleppo, the study aim to identification of\u00a0 selection indicators for local wheat Lips (Triticum durum)<\/em> under varying environmental conditions\u060c 25 durum wheat genotypes of (local lines) were planted in addition to 5 cultivars Cham 3, Cham 5, Cham 7, Cham 9 and Doma1 as a check verities under two treatments (water-stress) and (un-water stress) in a randomized complete block design with two replications Grain yield were studied and the percentage of reduction was estimated as result of drought stress, the Correlation between phonological \u00a0indicators (Days to Heading, Days to Maturity), morphological (peduncle length, spike length, Awn length), Flag leaf Area \u00a0and grain yield under both conditions was estimated for determining the most effective indices which were used to breeding programs\u060cqualities were studied use of path Analysis were studied for qualities to know the contribution of each attribute yields \u060cThe result showed the drought stress reduced grain yield for all genotypes significantly,\u00a0 the lowest decreases was observed in cham5 compared to the rest of control and genotypes with decrease of (8.15%) which gave the highest productivity in rainfed agriculture conditions by (3289 kg\/h) followed by the genotype Horani nawawy with a decrease of (9.85%) with a productivity of (2653 kg\/h). The result showed presence of positive and high moral genetic and phenotypic link between grain yield and (Grains Per Spike, 1000 \u2013 Kernel Weigh) While the link was negative and highly moral with (Days to Heading, Days to Maturity) the weight attribute of one thousand tablets is more contributing to yield with positive direct effect(0.35) in irrigated farming conditions\u060c in rainfed agriculture the results indicated a positive and highly significant genetic and phenotypic correlation between grain yield and (1000 \u2013 Kernel Weight, Spikes Per Unit Area, Flag Leaf Area, Awn Length) while the link was negative and highly moral with (Days to Heading, Days to Maturity) the number of spikes per square meter was the most direct attribute of yield with positive direct effect (0.282)\u060c the recipe for number of days until splicing had a direct negative effect on grain yield (-0.403). \u00a0<\/span><\/p>\n
