将大米草的染色体及其片段作为供体,在特定的条件下导入到受体水稻的细胞中,和受体细胞的水稻染色体进行染色体杂交,形成新型的大米草-水稻杂交染色体,获得大米草-水稻染色体杂交植株。与未经杂交的对照水稻比较,其植株、稻穗、谷粒等生物学性状均发生明显变化,抗盐碱性能极强,能在天然的重度盐碱地生长。对该大米草-水稻杂交植物的选育和其生物学性状作了简要的介绍。 The rice grass chromosome and its fragment as a donor, under specific conditions introduced into the recipient cells of rice, and recipient cells of rice chromosome chromosome hybridization to form a new type of rice grass - rice hybrid chromosomes to obtain rice grass - Chromosome hybridization plants in rice. Compared with the non-hybridized control rice, the biological characters such as plant, rice panicle and grain all changed obviously, and the performance of anti-salinity and alkalinity was very strong, which could grow in the natural heavy saline-alkali soil. Breeding and biological characteristics of the hybrid rice of rice grass and rice were briefly introduced.
