摘　　要：采用NCII遗传交配设计,以昌7-2、郑58、PH4CV、PH6WC为测验种,与12份阿根廷抗粗缩病自交系和群体配制48个组合,2015、2016年分别在河南洛阳、新乡、山东聊城进行产量及相关性状测定。结果表明,根据产量等性状的一般配合力,遴选出3份较为优秀的自交系CA1109、CA1107、CA1108,其中,CA1109的产量、出籽率、百粒重、穗粗等性状一般配合力较高,但株高、穗位偏高;CA1107的百粒重、穗粗以及降低株高和穗位高等性状一般配合力较高,但延长了生育期,且行粒数、出籽率减少;CA1108增加百粒重、穗行数、穗粗一般配合力较高,但延长了生育期,增加了株高和穗位高和收获时子粒含水量。根据产量SCA效应值,初步判定属SS类的有CA1303、CA1109、CA1106、CA1104,属NS类的CA1301、CA1101、CA1102。被测系CA1109、CA1107、CA1108直接利用选育出高产组合的可能性较大。Forty eight crosses were composed according to NCII design using Chang 7-2,Zheng 58,PH4 CV,PH6 WC as female tester with them.The hybrids were planted and its yield and related traits were surveyed in Luoy-ang,Xinxiang,Henan province and Liaocheng,Shandong province in 2015 and 2016.The results showed that threeinbred lines(CA1109,CA1107,CA1108)were selected according to the general combining ability(GCA)of yieldand its related traits.The inbred line CA1109 was better with higher GCA in yield,ear yield rate,100-grain weight,ear diameter,but it had poor agronomic traits in plant height and ear height.GCA of CA1107 was better in 100-grain weight,ear diameter and lower plant height and ear height,but extended maturity,and easily decreased kernelper row and ear yield rate.CA1108 increased 100-grain weight,rows per ear and ear diameter,but extended maturi-ty,increased plant height and ear height and grain moisture at harvest.According to SCA of yield,CA1303,CA1109,CA1106 and CA1104 were closer to SS,CA1303,CA1106 and CA1104 were closer to NSS.CA1109,CA1107 and CA1108 could be used directly to breed high-yield combinations.
