摘　　要：对郑 772 4 9种质与其 2 4个衍生新品种间共祖先度的分析和配合力测定结果表明 :该种质遗传基础丰富 ,农艺性状优良 ,抗病性强 ,配合力高 ,具有极高的利用价值。The coancestry coefficient and the combining ability of Zheng 77249 with its 24 derivative cultivars were analyzed. The results showed that the germplasm Zheng 77249 was possessed of rich genetic base, good agronomic performance, high disease resistance and high combining ability. Zheng 77249 and its derived germplasms should be used in soybean breeding in Huang Huai valley.
