贵州东部地区猕猴桃野生种质资源调查

Investigation on Wild Kiwifruit Germplasm Resources in the Eastern Part of Guizhou Province

为了解贵州东部地区猕猴桃野生种质资源分布现状及发掘具有育种价值的猕猴桃种质资源,对贵州东部地区猕猴桃野生种质资源进行调查。收集了6个猕猴桃种（中华猕猴桃、美味猕猴桃、毛花猕猴桃、阔叶猕猴桃、黄毛猕猴桃和软枣猕猴桃）共197份材料（枝条和果实）,海拔跨越590~1 691 m,其中美味猕猴桃、中华猕猴桃和毛花猕猴桃单果重分别高达55g、17g和20g。此外,野生猕猴桃种间具有同域分布及天然杂交现象。

To know the current distribution status of wild kiwifruit germplasm resources, and to find ki- wifruit germplasm resources with breeding value, we investigated in the eastern part of Guizhou province. Six Actinidia species （ A. delicious, A. chinensis, A. eriantha, A. latifolia, A. fulvicoma and A. argu- ta） and 197 materials （including branches and fruits） were collected with altitude in the range of 590 - 1 691 m, and the single fruit weight of the first three Actinidia species can reach up to 55 g, 17 g and 20 g, respectively. Moreover, sympatry and natural hybridization existed between different Actinidia spe-cies.
