摘要
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。

Abstract:
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.
