摘　　要：云南是誉满全球的“植物王国” ,作物遗传资源十分丰富。近年来已开展了大量的收集、保存、保护及评价利用方面的研究工作 ,但也还存在许多不利的影响因素。随着农业的集约化发展 ,出现了作物多样性急剧减少 ,作物品种单一 ,遗传基础狭窄等制约云南农业可持续发展的问题。只有最大限度地保护作物遗传多样性 ,大力开发新的作物种类和优良品种 ,使农业生产的良种多样化 ,并努力拓宽作物品种的遗传基础 ,才能实现我省农业的可持续发展。Yunnan is well known as a “Kingdom of Plant”. Yunnan is also rich in natural resources of crop. Lots of studies on collection, conservation, protection, evaluation and utilization of crop genetic resources have been done in recent years. But there are some unfavourable factors, too. With the agricultural intensity, some new problem such as decreasing diversity, simplifying varieties and narrowing genetic basis of crop have arisen to restrict the development of agriculture in Yunnan. The only way to achieve ...
