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

The\nstudy was carried out during 2016\/2017 season at AL-Sfira location which belongs to\nthe Scientific Agriculture Research\nCenter in Aleppo. The study aimed to select\ndrought tolerant tetraploid primitive wheat <\/strong>genotypes.\n22 genotypes of tetraploid primitive wheat belong to three types were: T.\npolonicum<\/em>, T. carthlicum<\/em> and T. dicoccom<\/em> in addition to 2\ncultivar; Cham5 and Bohouth7 as control that were planted in two trials (water-stress) and\n(un-water stress) in a randomized complete block design with two replications.\nGrain yield were studied and the percentage of reduction was estimated as a\nresult of water stress. Drought\ntolerance indices were assessed, also viz. Yield Stability Index (YSI),\nTolerance Index (TOL), Mean Productivity (MP), Geometric Mean\nProductivity (GMP), Stress Susceptibility Index (SSI) and Stress Tolerance\nIndex (STI). The correlations\nbetween drought tolerance indices and grain yield under both conditions were\nestimated for determining the most effective indices which were used to\nestimate Principle Component Analysis of genotypes, in addition, a Genotype Environment Interaction\n<\/strong>analysis was conducted. The results showed that the\ndrought stress reduced grain\nyield for all genotypes significantly, the lowest decrease was recorded for T.\npolonicum<\/em> (N.16) 21.44% which had the highest yield under drought stress\n(380 g\/m2<\/sup>), and the most effective indices were (GMP MP and STI) for\ndrought tolerance selection genotypes, and according to the values of drought\ntolerance indices the two genotypes 16 and 19 were the best genotypes followed\nby (20, 21). Principal Component Analysis revealed that the genotypes (16, 19,\n20 and 21) were the best genotypes\nunder the two treatments, and this conclusion was confirmed by genotype environment interaction\n<\/strong>analysis, which showed that the best genotypes were T<\/em>.carthilicum<\/em>\n(N. 20) and T. polonicum<\/em>\n(N.16) in terms of yield and stability under study environments. <\/p>\n\n\n\n
