IDENTIFYING TOLERANCE OF SOME WHEAT GENOTYPES TO WATER STRESS CONDITIONS | Journal of Global .....

One of the most detrimental abiotic stresses affecting wheat performance and yield is water stress. So, during the 2018/2019 and 2019/2020 winter seasons, a field experiment was conducted to assess the response of six wheat genotypes, namely Misr 1, Sakha 95, Giza 171, Shandaweel 1, Misr 2, and Gemmiza 9, to three water stress conditions, namely control, skipping one irrigation (the third irrigation), and skipping two irrigations (the fourth and fifth irrigation). Wheat yield and its components, as well as water relations, were measured at 70 days after sowing and expressed in chlorophyll (a &b) and proline concentration. The results showed that water stress treatments had a substantial effect on all analysed parameters, with all aforementioned features dramatically decreasing with increasing water stress conditions except proline content, which had the opposite trend due to wheat plant response under water stress. On the other hand, Sakha 95 was the best wheat genotype for water stress tolerance, while Shandaweel 1 was the worst wheat genotype for water stress tolerance. In terms of water productivity, it declined as the amount of irrigation water used increased.
