| 摘 要： | 本研究应用SSR标记分析了 18份野生稻不同基因组材料的遗传多样性。结果表明 :18份野生稻不同基因组材料可分为 3大组 ,即AA和BCD为一组、FF和GG为一组和HHJJ为一组 ;同一基因组内的野生稻亲缘较近 ,不同基因组间的亲缘较远 ;不同基因组的平均遗传多样性和亲缘关系远近的顺序为AA >BCD >BBCC >CCDD >CC >FF ,其中CC和CCDD基因组、FF、GG和HHJJ基因组间的亲缘性较高 ,并推测CC基因组中的药用野生稻 (O officinalis)和宿根野生稻 (O rhizomatis)可能是CCDD基因组的高秆野生稻 (O alta)、阔叶野生稻 (O latifolia)和重颖野生稻 (O grandiglumis)的共同母系亲本。 |

| Abstract: | The genetic diversity of 18 different genomic wild rices were revealed by using 30 SSR markers and neighbor joining method (NJ). The results showed that 18 wild rices were designated to 3 sections by NJ method, which are section of AA+BCD, FF+GG and HHJJ. There were a close relation within the same genome and a distant affinity among different genomes. The order of average genetic diversity and affinity of different genomic DNA were ranked as AA>BCD>BBCC>CCDD>CC>FF. It inferred that O.officinalis and O.rhizomatis designated to CC genomic wild rice were likely to be the common maternal parents of O.alta, O.latifolia and O.grandiglumis of CCDD genomic wild rice based on the affinity and dendrogram between CC and CCDD genomes. |
