从1972年开始,以滇-型红帽缨不育系为母本,以早熟晚粳华粳14号为父本进行测交和连续回交转育成华粳14号不育系,套袋自交100％不育,性状整齐一致。1976—1977年进行了300余个组合的测交,初步筛选出C_(57)等10多个对华粳14号不育系具有恢复能力的品种和株系,实现了三系配套。1977年对“华粳14号A×C_(57)”杂交粳稻进行了比较鉴定和栽培试验,结果良好,优势明显。与此同时,对繁殖制种及杂交种栽培技术进 Beginning in 1972, Dian-type red cap-sterility-male sterile line was used as female parent, early-maturing late japonica rice Huajing 14 as the male parent was crossed and backcrossed to the japonica CMS14. Pay 100% sterile, neat and tidy traits. In 1976-1977, more than 300 combinations were obtained, and more than 10 cultivars and strains were successfully screened for C_ (57), such as C_ (57). In 1977, “Huajing 14 A × C_ (57)” japonica hybrid rice were identified and cultivated, with good results and obvious advantages. At the same time, breeding and hybrid seed cultivation technology into
