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 a sustainable agriculture in Yunnan is doing our utmost to protect the crop diversity, develop new crop or new varieties and widen the genetic basis of crop varieties.

Key words: Crop genetic resources, Diversity, Sustainable agriculture, Yunnan province
