摘要

小麦是最重要的农作物之一,是人类粮食和粮食安全的基础。近年来显著的气候变化直接影响了小麦生产水平的形成。因此,在器官发生的初始阶段培育抗旱能力增强的品种,以及在干旱条件下形成高水平生产力的能力,是现代作物选择中的一项紧迫任务。本研究旨在评价不同方法下小麦品种的耐旱性水平,并在耐旱性选择过程中确定参与杂交的来源。采用室内和田间两种方法研究了所研究品种对干旱的响应:种子在蔗糖溶液中的萌发和按产量水平测定抗旱性指标。不同生态和地理来源的春小麦品种在乌克兰森林草原中部的条件下具有更高的生产潜力。结果表明,春小麦的干旱敏感程度存在较大的变异性。已经确定了抗旱性增强并能在胁迫因素下形成足够生产力的品种:Leguan(捷克共和国)和Koksa(波兰)。所得结果证明了通过经典育种方法在一个品种中组合提高抗旱性和产量水平的可能性。根据生产力指数与其他抗旱性指标的相关系数,指出了在进一步的育种实践中使用几何平均(比例平均)生产力(GMP)、抗逆性指数(STI)和产量稳定指数(YSI)指标的有效性。在作物育种中,将不同的耐旱性测定方法结合起来,在限制因子水分的影响下,客观地评价植物对胁迫因子的抗性,确定植物生长发育初期的生存力,这就决定了其实际研究意义

Drought resistance of soft spring wheat varieties of different ecological and geographical origins in the Forest Steppe of Ukraine
Wheat is one of the most important crops and the basis of human food and food security. Significant climate changes in recent years directly affect the formation of the level of wheat productivity. Therefore, the creation of varieties with increased resistance to drought at the initial stages of organogenesis, as well as the ability to form a high level of productivity in arid conditions is an urgent task in the modern selection of crops. The research aims to evaluate the level of drought tolerance wheat varieties different methods and to identify sources for involvement in crossbreeding during the selection of drought tolerance. Laboratory and field methods were used to study the researched varieties in response to drought: germination of seeds in a sucrose solution and determination of drought resistance indices by yield level. Varieties of spring wheat of different ecological and geographical origins have an increased productive potential in the conditions of the central part of the Forest Steppe of Ukraine. A wide range of variability in the degree of drought sensitivity of spring wheat was established. Varieties that have increased resistance to drought and can form a sufficient level of productivity under stress factors have been identified: Leguan (Czech Republic) and Koksa (Poland). The obtained results prove the possibility of combining in one variety an increased level of drought resistance and yield by classical breeding methods. According to the correlation coefficient between the productivity index and other studied indices of drought resistance, the effectiveness of using the Geometric Mean (proportional average) Productivity (GMP), Stress Tolerance Index (STI) and Yield Stability Index (YSI) indices in further breeding practice was noted. The practical research significance is determined by the combination of different methods for determining drought tolerance in crop breeding allowing for an objective assessment of resistance to stress factors and determination of viability at the initial stage of plant growth and development under the influence of the limiting factor – moisture
