摘要
It is of great importance for the analysis on genetic evolution mechanism, and rice breeding utilization by estimation and protection of genetic diversity of pre- sent DXWR （Oryza rufipogon Griff.）. This study has summarized genetic diversity and protection achievements of DXWR from many aspects like varied conservations, years, generations, other species of wild rice and cultivated rice. In this study, a u- nified and scientific evaluation system of genetic diversity is encouraged to be built and suggestions on research prospect and ecological conservation of DXWR genetic diversity have been proposed.
评价并保护现存"东野"的遗传多样性对解析其遗传进化机理以及在水稻育种上的利用有着重要意义。为此,综述了近年来不同保存方式、不同年份、不同世代以及与其他生态类型野生稻和栽培稻等多个角度有关"东野"遗传多样性及其保护研究成果认为应该建立科学统一的遗传多样性评价体系,并提出了"东野"遗传多样性研究前景和生态保护建议。
