小麦茎秆实心性状研究进展及育种应用
Research progress and breeding applications of wheat solid stem trait
摘要
Abstract
Wheat is one of the most important food crops globally,providing humans with substantial dietary protein and calories.However,its production is confronted with multiple challenges,such as lodging,wheat stem sawfly infestation,and extreme weather stress,which severely restrict the achievement of high and stable yield.Wheat solid stem not only significantly improves stem strength and enhances lodging resistance,but also forms a physical barrier to resist wheat stem sawfly infection.Meanwhile,it exhibits stronger adaptive advantages under abiotic stresses such as drought and high temperature,making it a crucial trait re-source for wheat stress-resistant breeding.This review systematically summarizes the research progress in aspects of the determi-nation period and methods of wheat solid stem trait,the origin,creation and utilization of germplasm resources,the genetic ex-pression characteristics and regulatory networks,the mapping of major QTLs and functional genes,as well as the synergistic rela-tionship between this trait and yield-related traits and the mechanism of stress adaptation.Additionally,the controversies and defi-ciencies existing in current research are summarized,and the future research directions and application prospects are prospected,aiming to provide theoretical basis for genetic improvement of wheat solid stem trait.关键词
