育种实践证明,致矮能力强的品种而后代伴随着较严重的生育后期性状恶化现象。从致矮能力与后代生育后期性状恶化较轻两性状的综合考虑,本文提出了致矮利用能力的概念;采用不完全双列杂交设计,利用多种性状评定其交叉点的方法,供品种资源工作者参考;利用这一方法评出了致矮能力相对强而后代生育后期性状恶化相对轻的亲本材料,供小麦育种工作者参考. Breeding practice has proved that the progeny resulting in short and strong progeny accompanied by more serious deterioration of late traits phenomenon. In this paper, we put forward the conception of the ability of short-term utilization due to the combination of the low ability and the less trait deterioration of the late progenies. In this paper, we use the incomplete double-line hybrid design to assess the crossing point of the traits with multiple traits, The reference of the worker; using this method, the parents material which caused the relatively short dwarf ability but relatively less deterioration of the progenies in later progenies was screened out for reference by the wheat breeding worker.
