中文摘要: 云南是柑橘起源中心之一,野生、半野生及农家品种柑橘资源十分丰富,许多资源为该地区所独有。然而随着地区经济的建设与发展,很多珍稀柑橘资源濒临灭绝。本研究拟系统开展云南地区野生、半野生及农家品种柑橘种质资源的调查、收集与保存。通过形态学分析,果实糖酸及苦味物质分析,基于核基因组的SSR与SNP、叶绿体基因组SSR分子标记技术,综合分析该地区野生、半野生及农家品种柑橘种质资源的遗传多样性,为科学保护和开发利用该地区独特柑橘资源奠定基础。

英文摘要: Yunnan is one of the origin centers of citrus, where are rich of wild, semi-wild and landrace citrus germplasm resources, and many resources are unique to the region. However, with the construction and development of the regional economy, many rare resources of citrus are in endangered. In this study, we will systematically carry out the survey, collection and conservation of local wild, semi-wild and landrace of citrus resources in Yunnan. According to the result of comprehensive analysis by the morphology, sugar, acid and bitter substances of fruit, nuclear SSRs and SNPs, chloroplast SSRs, it will give insights into the genetic diversity and genetic relationships in these rare resources, which will lay a foundation for scientific conservation and exploiting local unique Citrus germplasm resources in future.
