从广亲和品种与籼稻或粳稻的杂交组合中选育了120个高代稳定品系，以其作母本，分别与2～4个籼或粳测验种杂交配组，共配制约600个组合，以鉴定它们的亲和性，通过检测F1的小穗育性，从这120个稳定的品系中筛选出47个广亲和品系。另外，其它15个品系也初步鉴定为广亲和品系。主要农艺性状的评价表明这。47个广亲和品系绝大多数在亚种间F1代杂种优势利用中是有用的。
A total of 120 high-yielding stable lines were selected from the crosses between indica and japonica hybrids and their parents were crossed with 2-4 indica or japonica hybrids to produce about 600 combinations , To identify their affinity, by detecting F1 spikelet fertility, from the 120 stable strains of screening 47 wide compatibility strains. In addition, the other 15 strains were also initially identified as wide compatibility strains. The evaluation of the main agronomic traits shows this. The vast majority of 47 wide-compatibility lines are useful for F1 hybrid utilization among subspecies.
