几个玉米自交系主要农艺性状的配合力分析

摘要

采用不完全双列杂交法，研究不同自交系农艺性状配合力表现。结果表明：自交系 T0229的不同农艺性状的一般配合力都表现较高；在特殊配合力方面有3个组合表现较好：T0229×Mo17、T0201×齐319和 T0202×Mo17。综合一般配合力和特殊配合力表现，选育出比较有利用价值的的自交系 T0229以及组合 T0229× Mo17和 T0201×齐319。%In the study,the agronomic character combining ability of different inbred lines were analyzed with incomplete diallel crossing of NCⅡ method.The results showed that the inbred line of T0229 had higher gen-eral combining ability in different agronomic character of all tested inbred lines.T0229 ×Mo17、T0201 × Qi319 and T0202 ×Mo17 were better in special combing ability.There were a good inbred line T0229 and combinations T0229 ×Mo17 and T0201 ×Qi319 through the comprehensive performance between general com-bining ability and special combing ability.
