Genetic Characterization and Agronomic Evaluation of Drought Tolerance in Ten Egyptian Wheat (Triticum aestivum L.) Cultivars

This investigation was carried out for genetic characterization and determination of drought tolerance ten Egyptian cultivars wheat (Triticum aestivum L.), namely Misr 1, 2, Gemmiza 9, 10, 11, 12, Shandawel Giza 168, 171, Sids 14. These were grown in two winter seasons: 2018/2019 2019/2020 at the experimental farm Fac. Agric., Suez Canal Univ., Ismailia, Egypt, under watering regimes: normal (100%) stress (50% FC) conditions. Six agronomic traits five indices, (TOL), mean productivity (MP), geometric (GMP), yield stability index (YSI), susceptibility (DSI), used to evaluate impact stress. The results reflected 168 as precious germplasm breeding high-yielding drought-tolerant wheat. A highly significant positive correlation recorded between conditions on one hand each MP GMP other hand. In addition, YSI appeared engaged a with only. TOL DSI insignificantly correlated yield. Therefore, first runners among indices suitable distinguish At molecular level, primers Start Codon Targeted (SCoT) markers able resolve characterize studied cultivars, which SCoT potent gene-targeting marker, diversity cultivar level using few primers. is time-efficient it can efficiently replace genotypes high confidence reasonable cost.
