水稻早世代稳定现象是近年来发现的一种特殊现象,其中多个早世代稳定群体是在利用来自水稻双胚苗中的多倍体与不同二倍体材料杂交得到的。本实验利用一自然突变的多倍体,与二倍体水稻太平369杂交,F_1代大部分为非整倍体,其中5株为二倍体,收取这5株二倍体上的种子,种下得到 F_2群体且定名为718群体。该群体田间观察整齐一致,经过对田间调查数据和微卫星结果的分析,表明该群体为一早世代稳定群体。 The phenomenon of early generation stability in rice is a special phenomenon discovered in recent years, in which a number of early-age stable populations were obtained by crossing polyploidy with different diploid materials from rice double embryo seedlings. In this study, a polyploid with a natural mutation was used to hybridize with diploid rice Taiping 369, most of F1 progenies were aneuploid, of which 5 were diploid, and the 5 diploid seeds and seeds The F 2 population was obtained and named as the 718 population. This group of field observations neat and consistent, after field survey data and microsatellite results analysis, the group showed that the early generation of a stable population.
