| 摘 要： | 利用 3个抗大麦黄矮病毒 (BYDV)冬小麦材料作母本、4个丰产性品种作父本 ,采用 3× 4不完全双列杂交 ,研究分析其抗病性和丰产性遗传特点结果表明 ,抗病性状和产量性状的遗传均符合加性 显性遗传模型 ,以加性基因效应占绝对优势 ;抗病与高产二性状呈负相关 ,应以耐病高产为选择目标 ;抗病母本应具有较高的一般配合力和较低的特殊配合力方差 ,丰产父本应具有较高的特殊配合力方差。

| Abstract: | Using 3×4 incomplete diallel,the 3 mothers with resistant BYDV material and the 4 fathers with fertility varieties,the genetic characters of the disease-resistance and the fertility were analyzed.The results show that the heredity of disease-resistance and fertility are of additive-dominant genetic models,being predominant in additive effects;disease-resistance and fertility have a negative correlation, so the materials with tolerance to disease and high yield should be selected.The disease-resistance mother should have higher GCA and lower SCA variance,the father with fertility should have higher SCA variance. |
