| 摘要: |
| 对六十四个具有 T·timopheevi 细胞质杂交组合杂种 F1的优势指数、超亲优势、超标优势和相对优势进行统计分析,明确杂种 F1性状,完全显性和部分显性的表现程度。以简单相关与回归,明确杂种 F1亲子间关系,从而看出高产组合的千粒重、单株有效穗数和主穗结实粒数三个主要因素间的互补关系,为进一步选配高产组合提供依据。 |

| Abstract: |
| The heterosis index,the heterosis over parents and check variety and relative heterosis of 64 hybrid wheat crosses with T.timopheevi cytoplasm were studied. The result indicated that some of the crosses showed complete dominance whereas others incomplete dominance.with different analysis of simple correlation and regression revealed the relationship between certain characters of the parents and those of the offsprings. It was found that the characters 1000-kernel weight,number of productive tillers per plan... |
