摘 要 ：选用10个不同生态类型的大豆品种，在盆栽和大田条件下进行抗旱性研究.在正常供水与水分胁迫条件下，分别测定并分析了开花结荚期与品种抗旱性有关的多项生理生态指标.把大豆各性状的抗旱系数作为衡量各单项抗旱能力大小的指标，用主成分分析将各单项抗旱系数综合成几个新的、相互独立的综合指标，再利用隶属函数求出综合指标的隶属值，可以较准确地评价各大豆品种（系）的抗旱性.通过该方法评选出两个高抗旱大豆品种晋大74号和晋大53号，评定结果符合生产实际.

Abstract:The drought-resistance of ten soybean cultivars of various ecotypes was
investigated by pot culture and in field. At the stages from flowering and podding,
the physiological and ecological indices related to drought-resistance were
measured and analyzed under normal and water stress conditions. Taking each
drought-resistance coefficient as an index to measure single drought-resistance capacity, all drought-resistance coefficients were synthesized into
several new independent comprehensive indices by using principal component
analysis. On the bases of above results, subordinate values of comprehensive
indices were worked out by subordinate function, on which, the drought
resistance of different soybean cultivars or lines could be evaluated. By means
of this method, Jinda 74 and Jinda 53 were evaluated as two cultivars with
strong drought-resistance. The evaluation results corresponded well to the
fact.
