摘要
目前水稻遗传资源利用已经不能满足水稻现代育种的需求,对其近缘野生种种质资源的开发利用就显得尤为重要。虽然中国具有全世界最多的水稻种质资源储存量,但是近缘野生种(野生稻)种质资源较少,且材料来源分布不均衡,国外野生稻种资源仅占中国水稻近缘野生种种质资源保存量的10%。与中国相比,东南亚和南亚国家野生稻分布区物种丰富,气候条件与我国差异明显,这些地区的野生稻种质资源具有较高的潜在利用价值。本文总结了2009-2019年间对东南亚和南亚10个国家的普通野生稻和尼瓦拉野生稻野外考察结果,共收集2个物种66个群体,1504份个体数;分析了东南亚和南亚野生稻与中国野生稻的生态型差异及其生境特点;提出了未来在东南亚和南亚开展普通野生稻和尼瓦拉野生稻资源收集的重点区域。
The development and utilization of wild rice genetic resources are increasingly important given the fact that the genetic resources in cultivated rice(Oryza sativa L.)gene pool are insufficient to sustain the requirement in modern rice breeding.Although China hosts the world′s largest collection of cultivated rice germplasm,a large-proportion of stocks were domestically collected plus the alien wild germplasm accounting for only 10%.The wild rice germplasm resources,which are locally adapted to the diversified climates and habitats in countries from South and Southeast Asia,represent the high potential value in genetic development and breeding in China.In this paper,by summarizing the field surveys and collections of wild rice(O.rufipogon Griff.and O.nivara Sharma&Shastry)in 10 South and Southeast Asian countries from 2009 to 2019,1504 samples from 66 populations were collected.Considering the ecotypes of Oryza rufipogon Griff.and O.nivara Sharma&Shastry as well as environmental conditions in South and Southeast Asian countries,we proposed suggestions for future collection of wild rice resources in this region.
