| 摘 要： | 通过对15个高配合力亲本自交系及其组配的8个杂交种棒三叶有关性状及相关性的研究，揭示优良自交系的特征，探索亲本的搭配，予测杂种优势的大小。初步探明，自交系棒三叶中以穗位叶最长，上位叶最宽。棒三叶各叶面积大小差异不大，都起着同等重要的作用。父本的叶面积对杂交种叶面积大小的贡献较大，杂交种棒三叶叶面积和与杂交种单株产量成正相关。

| Abstract: | This paper studied relative characters and correlation of three ear leaf for 15 high combining inbred lines for select better inbred lines.studied that parents selected and mated,predicted heterosis.The results preliminary showed that the leaf on the ear in three ear leaves of inbred lines is the longest.The first leaf above ear is the widest.Amounts of each leaf area in three ear leaves was not significant differences.Then three ear leaves is aet important.The leaf area of male parent is much contribution to leaf area of hybrids.Sum of leaf area in three ear leaves was significantly positive correlative with yield of simpie plant of hybirds. |
