Abstract

Abstract:

7011S is a new indica type thermo-sensitive genic male sterile line, bred by the Rice Research Institute of Anhui Academy of Agricultural Sciences derived from the cross of 1892S and Gumei 4. It has the characteristics of good plant type, high chlorophyll content, strong tillering ability, low critical temperature of fertility alteration, high outcrossing rate, high combining ability, wide adaptability and so on. It was registered by the Anhui Provincial Crop Variety Approval Committee in 2019. The new two-line hybrid indica rice combination Liangyou 7002, developed by crossing 7011S as the female parent and R202 as the male parent, has the characteristics of high quality, high yield, and stress resistance. It was approved by the National Crop Variety Approval Committee in 2022.

Key words: hybrid rice, thermo-sensitive genic male sterile, 7011S, breeding

摘要：

7011S系安徽省农业科学院水稻研究所以生产上广泛使用的籼型两系不育系1892S为母本，与抗稻瘟病材料谷梅4号杂交、自交，经5年7代选育而成的籼型温敏核不育系。该不育系具有株型适中、叶色深绿、分蘖力较强、茎秆较粗、不育起点温度低、异交结实率高、配合力强及广适等特性，2019年8月通过安徽省农作物品种审定委员会鉴定。以7011S为母本、R202为父本配制的两系杂交籼稻新组合两优7002具有优质、高产、抗逆特点，于2022年通过国家农作物品种审定委员会审定。
