摘　　要：选用12份栽培大豆和28份野生大豆品种,在盆栽条件下进行抗旱性研究。在正常供水与水分胁迫条件下,分别测定并分析了与品种抗旱性有关的多项生态指标。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。通过抗旱性综合评价线性方程的构建,可以更加准确地评价各大豆品种(系)的抗旱性。通过该方法评选出一个高抗旱大豆品种铁豆36号和五个野生品种LYD01682、LYD02633、LYD01820、LYD02713、LYD01665,栽培种的评定结果符合生产实际。The drought-resistance of 12 soybean and 28 wild soybean cultivars of various ecotypes was investigated by pot culture.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,the drought resistance of different soybean cultivars and wild soybean or lines could be evaluated more accurate.By means of this method,Tiedou 36 and LYD01682、LYD02633、LYD01820、LYD02713、LYD01665were evaluated as one cultivar and five wild species with strong drought-resistance.The evaluation results of the cultivar corresponded well to the fact.
