冬小麦新品种选育方法的探讨

A Discussion on Breeding Methods of High Yielded,Drought Resistant New Winter Wheat Varieties

抗旱丰产冬小麦新品种（系）育种实践表明，在半干旱半湿润易旱生态环境条件下，选育抗旱丰产新品种的途径是：在较高群体基础上，通过提高千粒重，增加穗粒重；选择抗旱丰产突出的材料作亲本，早期世代采用水旱一体种植，两种生境条件下的交替选择，是快速培育抗旱丰产型冬小麦品种的一种新方法．

The breeding practices of new drought resistant,stable yielded winterwheat varieties showed that the method to select drought resistant,stable -- yielded winter wheat varieties under semi-aird and semi-humid ecological conditions should be:On the basis of higher populations,improve spike weight by means of the improvementof thousand grain weight;choose materials which are superior in drought resistance andhigh productivity as parents,plant the early generations both in irrigated and nonirrigated nurseries,and select the offsprings alterrnatively in the two ecological conditions.
