【摘要】 通过我国现用水稻广亲和性期测验品种间杂种F₁以及测验品种与其它籼、粳稻品种间杂种F₁的育性测验,分析水稻各个亲和性测验品种的亲和性,初步确定、粳型测验品种与一般籼稻品种的亲和性以巴利拉为最低,其次为秋光和有芒早少粳;籼型测验品种与一般粳稻品种的亲和性以南特号为最低,其次为南京11号和IR36、籼、粳测验品种亲和性的高低可作为该品种对粳、籼品种鉴别力的一个指标。更多还原

【Abstract】 In 1987, 6 rice varieties were proposed as standard testers for screening wide com. patibility varieties. They consisted of 3 varieties of japonica rice （Youmangzaoshajing from Jiangsu, China; Balilla from Italy and Akihikari from Japan） and 3 varieties of indica rice （Nantehao from Jiangxi, China; Nanjing 11 from Jiangsu, China and IR36 from Philippines）. An investigation was made to analyze the compatibility type for each tester from 1987 to 1989 through the fertility of F₁ between tester varieties and 20 eommertial varieties and the F₁ of different tester varieties as well. The lowest fertility was commonly found in F₁ when Balilla （japonica）was crossed with indica rice, or Nantehao （indica） crossed with japonica rice. On the other hand, moderate sterility often occurred in F₁ between indica rice and japonica rice when Youmangzaoshajing（japonica） or IR36 （indica） was used as a parent. It is postulated that the sterility of F₁ of the testers in various crosses could be served as a score to distinguish compatibility types of rice.更多还原
