摘　　要：通过对8个(9810×国内系)后代选系与国内属于不同优势类群的4个骨干自交系杂交组配的32个测交组合的配合力和杂种优势研究结果表明:南斯拉夫自交系9810具有较高的间接利用价值,在8个优良后代选系中,有2个选系的GCA为显著和极显著正值,具有较高的直接组配利用价值。在32个测交组合中,有8个单株产量显著或极显著高于对照6.6%～26.0%。This paper studied the indirect utilization of the introduced Yugoslavia inbred9810through8lines from9810×three Chinese inbred lines and their32testcrosses with Chinese elite inbred lines belonging to their high heterotic groups.The result showed that the Yugoslavia inbred line9810had higher indirect utilization value in breeding.In the8generation lines,the GCAs of2lines was significantly positive and had great value in breeding.The per-plant yield of8crosses was higher significantly than check by6.6%～26.0%in the32testcrosses.But their utilization value in production should be tested furthermore.
