摘 要 ：对于作物育种而言，早熟性是一种优良的综合抗逆性状。因此，探讨如何将常规育种方法和分子生物学技术相结合，用以缩短主要作物品种生育期，对作物生产的发展具有十分重要的意义。本文概括了作物早熟性相关性状，重点阐述了作物早熟性相关性状定位与遗传分析的研究现状，提出了目前作物早熟性育种研究中存在的问题与未来的研究展望。

Abstract:For the purposes of crop breeding, earliness is an excellent comprehensive resistant character. Therefore, exploring how to combine conventional breeding methods with molecular biotechnology to shorten the growth period of the main crop varieties has very important significance for the development of crop production. This paper summarizes the crop earliness related traits, focuses on the current situation of related traits location and genetic analysis of crop earliness and proposes existing problems in current crop earliness breeding and future research prospects.
