| 摘 要： | 通过３年对９８６份新育成小麦品种（系）抗旱性鉴定研究结果分析，将参试品种根据其性状抗旱指数的等级数值之和划分为抗旱型、中间型和不抗旱型；根据小麦性状对不同时期的水分胁迫反应的稳定性分为综合性状稳定型、穗数稳定型、粒数稳定型、株高稳定型和千粒重稳定型。这种划分对实现小麦品种合理布局，充分发挥品种增产作用和育种上有效地选择亲本种质具有极其重要的应用价值。

| Abstract: | The result of drought resistant evaluation to 986 new bred varieties was analysed inthis paper. According to drought resistant index,the varieties tested were divided intodrought resistant type,middle type and non-drought resistant type. On the basis of sta-bility of wheat trait to water stress in varied stage ,the wheat varieties were classifinedinto comprehensive traits stable type ,spike number stable type ,kernal number stabletype,plant height stable type,and 1000-grain weight stable type. The study was very im-portant to variety opportune ditribution, giving full play to a variety in its yeild andchoosing parant in breeding. |
