1974年开始,以B型台中65不育系为母本,以中熟晚粳农进2号为父本进行测交和连续回交转育成农进2号不育系。套袋自交100％不育,群体性状整齐一致,1976—1978年进行了200多个组合的测交,初步筛选出40多个对农进2号不育系具有较强恢复能力的株系,已经三系配套。经湖北、浙江、江苏、安徽等省多单位引种鉴定,均对农进2号不育系反映较好。现将农进2号不育系的基本情况简报如下:
Beginning in 1974, B-type Taichung 65 male sterile line was used as female parent, and middle late japonica rice line Nongjin 2 was used as male parent to test and continuous backcross breeding into Nongjin 2 CMS. Bagging selfing 100% sterile, group trait neat, 1976-1978 more than 200 combinations of cross dating, the initial screening of more than 40 pairs of Nongjin 2 CMS lines have strong ability to restore strains , Has three lines supporting. By Hubei, Zhejiang, Jiangsu, Anhui and other provinces more than the introduction of identification, are on the 2nd of the Nongjin sterile line to reflect better. Brief introduction of the basic situation of Nongjin No. 2 CMS is as follows:
