摘要
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。
120 stable strains were obtained from cornbinations between wide compatibility varlety WCV and Indica or Japonica rice. Their compatibility was tested by crossing with 2 to 4 Indica or Japonica rice varieties. A total of 600 crosses were testod for their compatibility. Finally, 47 wlde compatibility strains (WCSs) were identified from the 120 stable strains by panicle fertility of tested F1. Other 15 strains were probably identified as WCSs.47 WCSs were evaluated for their agronomic characters. The results showed that most of 47 the WCSs were useful in the exploralion of inter-subspecies heterosls inrice.
