中国野生稻多样性的评价与保护研究进展

野生稻资源在水稻育种中占有重要的地位,是天然的基因库.中国现有普通野生稻、药用野生稻和疣粒野生稻分布,均已成为濒危物种.因此,对现存野生稻资源的多样性进行全面深入评价和科学有效地保护刻不容缓.同时,野生稻的多样性研究对其自身的遗传进化探讨以及在遗传育种上的利用有着重要意义.现有的研究表明,中国野生稻具有丰富的多样性,切实有效的多样性保护方法也在不断地探索与实践.回顾了近年来有关中国野生稻多样性的评价与保护研究成果,并讨论了存在的问题与研究前景.

Advances of diversity evaluation and protection in wild rice in China

As a natural gene bank,wild rice occupies an important position in rice breeding.There distributed Oryza rufipogon Griff.,O.officinalis Wall.and O.meyeriana Baill.in China,and they were all endangered species.So it is immediacy to further comprehensive study and effectively protect on diversity of existing wild rice resources.Meanwhile,study on the diversity of wild rice has important significance for discussion its genetic evolution and utilization in breeding.A lot of studies declared that the diversity o...
