| 摘 要： | 在抗旱高产小麦新品种选育中，采用渐近杂交法使目标性状得到有效的组合，采用水、旱地交叉选育法，为杂种后代基因型的潜在遗传特性的充分表达和选择提供了条件，使自然选择、人工选择和定向培育三者紧密地结合在一起，加大了选择压力和频率，提高了选种质量和效率，提高了选种质量和效率，为选育抗旱、高产、稳产小麦品种提供了一种新方法。

| Abstract: | In the breeding of new wheat variety with drought resistance and high yield,the progressive crossing method was used to gain efficient combination of target character.The condition was offered by cross selection in irrigated field and dry field for the potential hereditary character of hybrid descendant gene to be fully appeared and selected.This method can closely integrate natural selection,artificial selection and directive breeding into one uniform, and increase the pressure of selection and frequency, raise the selection quality and efficiency. It is a new way breeding a wheat variety with drought resistance high yield and stable yield. |
