摘　　要：[目的]旨在研究不同黑花生品种在干旱环境下农艺、经济、生理和品质性状的表现规律,并对品种干旱适应性进行函数评价。[方法]通过山西南部种植的12份黑花生品种(系)盆栽水旱试验,采用多性状隶属函数方法分析、评价各品种(系)的抗旱性。[结果]与黑花生直接抗旱系数相关性较高的农艺经济性状指标为荚果产量、籽仁产量、主茎高、单株生产力、百仁重,生理品质性状相关性较高的3个指标为蒸腾速率、净光合速率、含油量,抗旱相关最高性状(荚果产量)是最低相关性状(油亚比)的24.5倍,黑花生生理、品质性状与抗旱系数的相关性要低于农艺经济性状;D_(农经)与D_(总)、D_(农经)与抗旱系数、D_(总)与抗旱系数之间极显著相关(P<0.01),而D_(生理)、D_(品质)与D_(总)、抗旱系数之间的相关性达不到显著水平(P>0.05);按照不同参试黑花生品种(系)各性状隶属函数值及综合抗旱D值,可将其分为4类,抗旱型、较抗旱型、弱抗旱型、不抗旱型。[结论]相较于单产量性状抗旱系数等方法的直接鉴定,多性状间接隶属函数D值方法可筛选出综合抗旱性较强的4个黑花生品种(系),晋花9号、中花9号、赣花9号和临黑5号,抗旱评价更为科学、准确。研究结果可为黑花生旱作栽培及种质鉴选提供理论参考。[Objective]This study aimed to investigate the performance of different black peanut varieties under drought conditions in terms of agronomic,economical,physiological and qualitative characters,and to evaluate the drought adaptability of different varieties.[Methods]The watering and drought experiments were conducted with 12 black varieties commonly cultivated in Southern Shanxi.The drought resistance characters of different varieties were analyzed and evaluated via multicharacter membership function method.[Results]The results indicated that the agronomic and economic traits that were highly correlated with the direct drought resistance coefficient of black peanut varieties were pod yield,seed yield,stem height,pod yield per plant and weight per hundred kernels.Transpiration rate,net photosynthetic rate and oil content were three indexes that were highly correlated with physiological quality traits.The highest drought resistance related traits(pod yield)was 24.5 times higher than the lowest drought resistance related traits(oil-yield ratio).The correlation between the physiological and quality traits of black peanuts and the drought resistance coefficient was lower than that of agronomic and economic traits.A significant correlation was detected between agricultural economic traits synthetical D value and total traits D value,between agricultural economic traits synthetical D value and direct drought resistance coefficient,and between total traits D value and direct drought resistance coefficient(P<0.01);while the correlation among physiological traits D value,quality traits D value and total traits D value,direct drought resistance coefficient was not up to significant level(P>0.05).According to the membership function value of each trait of different tested black peanut varieties and the comprehensive drought resistance D value,the black peanut varieties could be divided into four categories,including drought-resistant,relatively drought-resistant,weakly drought-resistant and drought-susceptible types.[Conclus
