摘　　要：调查铜仁市现有板栗野生资源并进行初步的性状鉴定与评价,为保护铜仁市板栗野生资源、乡土品种选育等奠定基础。从碧江、玉屏、江口3个群体中选择大粒型油板栗、小粒型油板栗、大粒型灰板栗、小粒型灰板栗和独板栗5个类型共1 000株,对不同品种板栗生长情况、结果情况以及种仁营养成分含量进行调查,并鉴定其性状,采用平均隶属度法对不同品种野生板栗性状进行综合评价。结果显示,玉屏大板栗垂支栗12号品种性状表现最好,种仁营养成分含量较高,产量也比较高,且植株形态良好,综合效益比较高。可将玉屏大板栗垂支栗12号品种作为野生板栗杂交亲本,培育树冠紧凑的种质资源,在铜仁区域内推广种植,积极推动铜仁市板栗资源开发利用。The existing wild resources of Chinese chestnut in Tongren were investigated and preliminary character identification and evaluation were carried out,which laid the foundation for protecting wild resources of Chinese chestnut in Tongren and breeding local varieties.A total of 1000 plants were selected from five types:large-grain chestnut,small-grain chestnut,large-grain gray chestnut,small-grain gray chestnut and single-grain chestnut from the three populations of Bijiang,Yuping and Jiangkou.The growth,fruit and nutritional content of seeds of different varieties of chestnut were investigated,and their traits were identified.The average membership method was used to evaluate the characters of different varieties of wild chestnut.The results showed that Yuping big chestnut Chuizhili No.12 had the best character performance,the kernel nutrition content was high,the yield was relatively high,and the plant shape was good,the comprehensive benefit was relatively high.Yuping big Chestnut Chuizhili No.12 can be used as the hybrid parent of wild chestnut,and the germplasm resources with compact crown can be cultivated and popularized in Tongren region,so as to actively promote the development and utilization of chestnut resources in Tongren City.
