优质籼型水稻三系不育系荃科1A的选育与应用OA
Breeding and Application of High-Quality Indica CMS Line Quanke 1A in Rice
荃科 1A是安徽荃银高科种业股份有限公司以淡绿叶突变体Y834 为母本、荃 9311B为父本杂交,在后代中选择携带抗稻瘟病主效基因pigm的优良单株,与荃 9311A测交并经多代连续回交育成的优质籼型三系不育系,于 2021 年通过安徽省农作物品种审定委员会鉴定.该不育系具有叶色淡、配合力强、柱头外露率高、抗稻瘟病、早熟等特点,所配组合荃科优 822、荃科优 9085 和荃科优 1802 均已通过国家农作物品种审定委员会审定.介绍了荃科 1A的选育过程、特征特性及繁殖技术要点,以期为荃科 1A系列组合的开发利用提供参考.
Quanke 1A is a high-quality indica cytoplasmic male sterility(CMS)line developed by Anhui Win-All High-Tech Seed Co.,Ltd.It was bred through crossing Y834(the female parent,a light-green leaf mutant)and Quan 9311B(the male parent).Superior individuals carrying the major rice blast resistance gene pigm were selected from the progeny,test-crossed with Quan 9311A,and then backcrossed continuously for multiple generations.In 2021,Quanke 1A was approved by Anhui Provincial Crop Variety Appraisal Committee.This CMS line exhibited multiple advantageous traits,including pale leaves,strong combining ability,a high stigma exsertion rate,rice blast resistance,and early maturity.Among the combinations derived from Quanke 1A,Quankeyou 822,Quankeyou 9085,and Quankeyou 1802 were approved by the National Crop Variety Appraisal Committee.This paper introduced the breeding process,characteristics,and multiplication techniques of Quanke 1A,aiming to provide a reference for the development and utilization of a series of combinations derived from Quanke 1A.
