Research Progress on Breeding of Sterile Lines in Japonica Rice in China
摘要
Abstract
Based on the data on japonica rice sterile lines collected by the National Rice Data Center,a comprehensive statistical analysis has been conducted on the number,stigma exposure rate,outcrossing rate,and rice quality of approved japonica rice sterile lines in China over the past 20 years.Through systematic organization of these data,a summary of the current status of breeding,as well as the application of japonica rice sterile lines in China,has been presented.Furthermore,this paper provides a detailed analysis of the issues encountered in the breeding and application processes of japonica rice sterile lines,and proposes targeted breeding strategies accordingly.The research results revealed that,in terms of the number of approved japonica rice sterile lines,BT-type sterile lines occupy a dominant position;among the types of abortion in japonica rice sterile lines,chromosomal abortion is predominant;and there was still room for further improvement in the quality and outcrossing rate of japonica rice sterile lines.关键词
