Breeding and Application of High-quality Indica CMS Line Quanguang A in Rice
摘要
Abstract
Quanguang A is a high-quality CMS line developed by Anhui Win-all High-tech Seed Co.,Ltd.It was bred by artificial hybridization with Guang 8B as the female parent and Quan 9311B as the male parent,followed by test-cross and backcrossing for multiple generations with Quan 9311A after molecular breeding.Quanguang A was characterized by compact plant type,thick stems,strong tillering ability and good grain quality.In 2019,it was technically identified by Anhui Provincial Crop Variety Appraisal Committee and authorized as a new plant variety(CNA20191001577)by the Ministry of Agriculture and Rural Affairs.Quanguang A showed excellent performance in hybrid combination breeding.In 2021,the hybrid combinations Quanguangyou 879,Quanguangyou 851 and Quanguangyou 822 developed with Quanguang A were all approved by the National Crop Variety Appraisal Committee.These three hybrid combinations showed significantly higher yields and the maturity 3.0～5.1 days earlier than the control.The grain quality of Quanguangyou 851 reached the first grade of the agricultural industry standard Cooking Rice Variety Quality,and that of Quanguangyou 879 and Quanguangyou 822 reached the second grade.The breeding process,characteristics and multiplication techniques of Quanguang A were introduced.关键词
