摘　　要：为明确小麦阶段发育理论在小麦育种中的价值,提高小麦育种效率,对近年来春化阶段和光照阶段理论与育种关系研究进行了综述,并提出了感温阶段概念。总体来看,小麦品种春化阶段低温大小、光周期反应强弱和感温特性差异与冬春麦分类、小麦不同生态型区域分布和品种适应范围大小等关系十分密切。并利用此理论,可显著提高小麦育种中组合配制、杂种后代选择和稳定品系处理效率及增加育种的预见性,并对小麦栽培技术合理运用等提供依据。To know the value of wheat phasic development in wheat breeding,improve the wheat breeding effi ciency, the relationship between vernalization, photoperiod and wheat breeding was reviewed and the concept of wheat temperature sensitivity was proposed. Generally,differences among wheat cultivars in vernalization, pho toperiod and temperature sensitivity was closed related with the classification of winter and spring wheat,areas allocation of various ecological type wheat and adaptability of cultivars. Through taking advantage of this knowledge, breeders could improve efficiency in screening of females and males in hybrid wheat breeding,selec tion of hybrid progeny and treatment of elite lines. It was also help for operating wheat cultivation technology reasonably and providing prediction for wheat breeding.
