摘  要:
通过对两组共 8个部分近亲玉米自交系主要农艺性状杂种优势和配合力的分析 ,结果表明 :9个性状的一般配合力差异显著或极显著 ;而特殊配合力方差 ,Ⅰ 组的百粒重和穗位高、Ⅱ 组的所有性状差异极显著 ;两组的杂种优势表现十分相似 ,从大到小的排列次序完全相同 ,其中单株产量最高 ,而行粒数最小

摘  要:
The results showed that the GCA of 9 traits was significant difference.The SCA,100 grain_weight and ear height of No.1 group,all characters of No.2 group,were significant difference.It was the same that the heterosis of two groups was arranged from small to large order.The maximum one was weight of grain per plant and the minimum one was kernel number per row.
