Climate change realities such as high-temperature levels are among the causes of drought episodes affecting the productivity and yield stability of crops worldwide. Breeders, therefore, have a daunting challenge to overcome and a large gap to seal in the agricultural sector arising due to drought through the improvement of new tolerant germplasm. It is in this endeavour that the present study, which included nine winter wheat genotypes grown in the greenhouse, was conducted to evaluate their performance under well-watered and drought stress treatments for the traits: heading time, plant height, above-ground biomass, seed number/plant, grain yield/plant, harvest index, root length and root dry mass. A lower grain yield/plant was observed for each studied genotype under drought stress conditions than for those under well-watered conditions. Additionally, grain yield/plant depression varied from 69.64 to 81.73% depending on the genotype. Positive significant correlations between grain yield/plant and heading time, above-ground biomass, and seed number/plant under the drought stress treatment were obtained. Genotypes that recorded high root dry mass had both high above-ground biomass and seed number/plant under drought stress conditions. Positive correlations between grain yield/plant depression and plant height, seed number/plant, and harvest index depressions were also observed. Grain yield for each genotype under drought stress conditions was recorded, and the varieties ‘Plainsman V.’, ‘GK Berény’ and germplasm ‘PC61’, ‘PC110’ showed the best drought tolerance. These genotypes and germplasm will be used in different drought tolerance experiments and breeding programmes.

冬小麦 (Triticum aestivum L.) 种质耐旱性的表征

高温等气候变化现实是干旱事件的原因之一，影响了全球作物的生产力和产量稳定性。因此，育种者需要克服一项艰巨的挑战，并通过改良新的耐旱种质来填补农业部门因干旱而产生的巨大差距。正是在这一努力中，本研究包括在温室中种植的九种冬小麦基因型，旨在评估它们在水分充足和干旱胁迫处理下对以下性状的表现：抽穗时间、株高、地上生物量、种子数/株、谷物产量/株、收获指数、根长和根干质量。在干旱胁迫条件下观察到每个研究的基因型比在充分浇水条件下的谷物产量/植物低。此外，取决于基因型，谷物产量/植物抑制率从 69.64% 到 81.73% 不等。获得了干旱胁迫处理下粮食产量/株与抽穗期、地上生物量和种子数/株之间的正显着相关性。记录高根干质量的基因型在干旱胁迫条件下具有高地上生物量和种子数/植物。还观察到谷物产量/植物抑制与株高、种子数/植物和收获指数抑制之间的正相关。记录了每个基因型在干旱胁迫条件下的产量，品种'Plainsman V.'、'GK Berény'和种质'PC61'、'PC110'表现出最好的耐旱性。这些基因型和种质将用于不同的耐旱实验和育种计划。取决于基因型，谷物产量/植物抑制率从 69.64% 到 81.73% 不等。获得了干旱胁迫处理下粮食产量/株与抽穗期、地上生物量和种子数/株之间的正显着相关性。记录高根干质量的基因型在干旱胁迫条件下具有高地上生物量和种子数/植物。还观察到谷物产量/植物抑制与株高、种子数/植物和收获指数抑制之间的正相关。记录了每个基因型在干旱胁迫条件下的产量，品种'Plainsman V.'、'GK Berény'和种质'PC61'、'PC110'表现出最好的耐旱性。这些基因型和种质将用于不同的耐旱实验和育种计划。取决于基因型，谷物产量/植物抑制率从 69.64% 到 81.73% 不等。获得了干旱胁迫处理下粮食产量/株与抽穗期、地上生物量和种子数/株之间的正显着相关性。记录高根干质量的基因型在干旱胁迫条件下具有高地上生物量和种子数/植物。还观察到谷物产量/植物抑制与株高、种子数/植物和收获指数抑制之间的正相关。记录了每个基因型在干旱胁迫条件下的产量，品种'Plainsman V.'、'GK Berény'和种质'PC61'、'PC110'表现出最好的耐旱性。这些基因型和种质将用于不同的耐旱实验和育种计划。
