我国开展杂交水稻研究以来,籼、粳型杂交组合相继问世,但多属粘性,糯性杂交稻甚少。为填补这一空缺,我所自1984年夏季开始,以早熟籼型糯稻“619”与珍汕97A测交,并经过连续三年6代的择优回交转育,于1987年夏B6F1的不育性已相对稳定,糯性基本纯合。同时,自B4F1开始,以高不育株与 Since China has carried out research on hybrid rice, indica and japonica hybrid combinations have come out one after another, but they are mostly sticky, with few waxy hybrid rice. In order to fill this vacancy, we started to test early summer Indica glutinous rice “619” and Zhenshan 97A, and after 6 consecutive generations of 6 generations of selective backcross breeding, in the summer of 1987, B6F1 Fertility has been relatively stable, waxy basic homozygosity. At the same time, starting with B4F1, with high infertile strains
