Abstract

Abstract:

Rice blast is a major disease that damages rice production. Molecular marker assisted selection（MAS） has become an important method for breeding disease-resistant varieties. In this study, the broad-spectrum resistance gene pi9 from DW808 was imported into R894 with good regional adaptability. Qianhui 101, a rice blast-resistant restorer line, was selected through molecular marker testing, field natural identification and artificial inoculation identification. Its combination, Anyou 101, participated in the Guizhou Rice Regional Trial in 2017 and was approved by Guizhou provincial crop variety appraisal committee in 2019.

Key words: hybrid rice, rice blast resistance, MAS, restorer line, Qianhui 101

摘要：

稻瘟病是危害水稻生产的主要病害,分子标记辅助选择（MAS）已经成为选育抗病品种的重要方法。本研究以含有广谱抗性基因pi9的DW808为供体亲本,导入区域适应性好的受体亲本R894;经过分子标记检测、田间自然鉴定、人工接种鉴定,选育出中抗稻瘟病的恢复系黔恢101;其组合安优101于2017年参加贵州省水稻区域试验,2019年通过贵州省审定。
