摘要
采用盆栽方法,在花生结荚期对花生品种(系)进行了轻度、中度、重度干旱胁迫处理(以正常供水为对照),在花生成熟期对根及荚果干物质量进行了测定。通过产量抗旱系数法、品种综合指数法,对22个花生品种(其中15个品种为高油酸花生)抗旱性进行评价与分析。结果表明,不同花生品种抗旱性存在显著差异:开农1768、山花11、DF31、L52、开农65、CTWE、花育662、阜花27、冀花16、远杂9102干旱地区适应能力最强;品种花育962、濮花28、S51、FB4、花育20、鲁花15干旱地区适应能力较强;L107、潍花13、阜花22、花育27、漯花6号、吉花4号干旱地区适应能力差;以重度干旱胁迫强度(30±5)%,可以更准确地鉴定花生品种(系)的抗旱性。
The peanut varieties(lines)were subjected to mild,moderate,and severe drought stress during the peanut pod setting period using a potted method(with normal water supply as the control),and the dry matter quality of roots and pods was measured during the peanut ripening period.Evaluate and analyze the drought resistance of 22 peanut varieties through the yield drought resistance coefficient method and variety comprehensive index method.According to yield-drought coefficient and composite index the peanut varieties were divided 3 grade.The most adaptable varieties in arid regions were Kainong1768,Shanhua11,DF31,L52,kainong65,CTWE,Huayu662,Fuhua27,Jihua16,Yuanza9102.The stronger adaptable varieties include Huyu962,Puhua28,S51,FB4,Huyu20,Luhua15.The poor adaptable varieties include L107,Weihua13,Fuhua22,Huayu27,Luohua6,Jihua4.On severe stress can be more accurate evaluated of the peanut varieties compared with the 3 intensity.
