摘    要: 就水稻恢复系T984及其7个系谱亲本C57、京引35、300号、 科情3号、IR26、IR24和IR8的亲和性进行了测定分析。结果表明受测的7个系谱亲本均不具有广亲和性,而T984却具有广亲和性,其与南京11、秋光和早沙粳测交F1的结实率分别为72.84%、74.42%和67.24%。从而证实了非广亲和性的籼粳亚种间杂种后代也可产生广亲和的品种.

关 键 词:水稻  系谱  广亲和性  遗传

Abstract:The wide compatibility and indica-japonica differentiation of T984 and its seven pedigree parents i. e. C57, Jingyin 35, No. 300, Keqing 3, IR26, IR24, IR8 were tested. The result indicated that none of these seven pedigree parents showed wide compatibility. However the rice variety T984 which was originated from above seven varieties showed wide compatibility, when it was crossed with indica(Nanjing 11) and japonica (Akihikari and Zaoshajing) testers, their hybrids gave an almost normal fertility of 72.84%, 74.42% and 67.24%, respectively. In conclusion, the wide compatible lines can also be generated from hybridization between indica and japonica varieties both of which do not show wide compatibility.
Keywords:Genetics  Pedigree analysis  Wide compatibility
