摘要
科丰A属感温型水稻三系不育系,其花粉败育彻底,不育株率和花粉不育度均达到100%,具有抗性好,配合力强,易于繁殖,适应性强等特性,以科丰A配组育成的三系杂交稻科优769、科优16等品种分别通过广东省梅州市和国家品种审定。介绍了科丰A的特征特性及其利用与高产繁殖技术。
In this paper, the characteristics for a rice male sterile line Kefeng A were introduced. Kefeng A was developed by Nanping Institute of Agricultural Sciences and released by the Fujian province in 2013, which showed stable sterility which had sterile plant percentage of 100%, pollen sterility of 100%, high exserted stigma rate, good combining ability and good quality.
