Research Progress on Outcrossing Characteristics of Parental Lines in Hybrid Rice
摘要
Abstract
Hybrid rice has made significant contributions to grain production due to its remarkable yield advantage.However,its development has been constrained in recent years by the relatively high cost of seeds.To reduce seed costs,it is necessary to increase seed production yield.The outcrossing ability of male sterile lines and restorer lines in hybrid rice directly affects the seed production yield.This paper summarizes the research progress on the outcrossing characteristics of hybrid rice parents,focusing on the synchronization of flowering time and duration,plant traits of male sterile lines,stigma characteristics and vitality,as well as the in vitro viability and quantity of pollen from restorer lines.It also discusses the impact of weather conditions on flowering periods and outcrossing seed setting.Finally,some strategies are proposed to enhance seed production efficiency,aiming to achieve high-yield seed production in hybrid rice and promote cost reduction and efficiency enhancement in hybrid rice seed production.关键词
