植物种质资源的研究工作一直受到世界各国的重视,在我国也是重点研究课题之一。我国具有丰富的植物种质资源,仅苹果属就有23个种和100多个变异类型,为苹果种质资源的研究提供了丰富的基因源和种质材料。为了更好地发掘研究我国的果树种质资源,国家在全国各地先后建成了14个果树种 Research on plant germplasm resources has always been valued by all the countries in the world and is also one of the key research topics in our country. China has rich plant germplasm resources. There are only 23 species and more than 100 mutation types in apple genus, which provide abundant gene sources and germplasm materials for the research of apple germplasm resources. In order to better explore the fruit germplasm resources in our country, the country has built 14 fruit trees throughout the country
