| 摘 要： | 本文用双列杂交试验资料分析了玉米自交系的两种配合力在 F_1代的表现:杂种优势取决于双亲的配合力总效应;特殊配合力效应(?)与 F_1的相关性比一般配合力效应(?)更为密切;(?)是直接形成杂种优势的主要原因。杂交组合的两种配合力间呈中等程度的正相关;配合力变化时,(?)的变化远大于(?)均,(?)与高(?)间有更密切的正相关。(?)与

| Abstract: | The Performenee of two combining abilities in F_1 of corn inbred lin-es was analysed with crossing test data.The results were as follows:the heterosis was decided by the parent's total effect of combining abi-lities;the relationship between the effect of specific combining ability(?)and F_1 was clos |
