| 摘 要： | 提出了小麦节水型品种应具备的特点及两圃平行交替选择节水型品种的遗传改良技术,突破了常规育种技术单一选种环境、遗传类型不能充分表现的缺陷;通过加大逆境选择压力以及后代材料逆境与非逆境的交替选择,多抗节水高产品种的遗传改良效果显著。

| Abstract: | Put forward water-saving wheat varieties features and its breeding technology of parallel alternative selection of two seed plots,break through the shortcomings of conventional breeding technology,such as single selection environment,no fully showing genetic types;Through increasing selection pressure in adverse circumstances as well as progeny's alternative selecting in adverse and favorable circumstances,the effect of genetic improvement of multi-resistant water-saving high-yield wheat varieties is significant. |
