关于修订桃种质资源(Prunus persica)描述体系的建议

Suggestion on the Amendment of the Descriptor of Peach Genetic Resources

评价是种质资源工作的重要环节之一,是资源利用与共享的基础。目前,中国桃种质资源的评价描述体系一般是按照中国1990年编制的“桃种质描述符”进行。通过对国际植物遗传资源委员会1980年编制“桃描述系统″和中国“桃种质描述符”在评价的层次、评价内容、评价方法和评价标准的系统比较,以及2个标准在种质资源科研实践使用过程中存在的不足之处,结合中国桃种质资源工作的特点和国外资源的描述方法的新进展,提出中国桃种质资源描述系统的修改建议,为建立中国标准化、数字化的桃种质资源描述系统奠定基础。

Characterization plays an important role for people to know and identify fruit genetic resources. It also gives the basic materials for assessment of the genetic resources. After studied and compared the International Peach Descriptor issued by IGRIP in 1980 and the Chinese Peach Descriptor of 1990, we believe that the IGRIP Peach Descriptor has good passport data and preliminary data system, but it is short of value index in the further characterization and evaluation, and the Chinese Descriptor is short of reference and has different scales. So the authors would try to give an amended one in this article.
