摘　　要：为了开发利用软枣猕猴桃野生资源,针对主要2007—2008年长白山软枣猕猴桃野生资源调查结果,对软枣猕猴桃果实多样性和染色体倍数性进行了分析。结果表明:长白山野生软枣猕猴桃果实表现出一定的多样性,大部分果实的果形指数在1.0~1.3,偏向于圆柱形,少部分果实果形指数小于1.0和高于1.3。大部分果实大小在4.43~9.34g,在蛟河市境内发现了单果质量为19.74g的大果型软枣猕猴桃资源类型;在安图县境内发现了着色型和高糖型软枣猕猴桃资源类型。长白山野生软枣猕猴桃为四倍体,目前还未发现其它倍数性种类。The wild resources of Actinidia arguta in Changbai Mountain were used to analyze fruit diversity and chromosome ploidy in order to developing and using in 2007—2008.The results showed that Changbai Mountain wild Actinidia arguta fruit showed a certain diversity,the fruit shape index of most fruit between 1.0-1.3,biased towards a cylinder,the fruit shape index of fewer fruit were less than 1.0 and higher than 1.3.Most of the fruit size between 4.43-9.34 g,a single fruit weight of 19.74 g large fruit type of Actinidia arguta resource types were found in Jiaohe country.The colored and high-sugar type of Actinidia argutaresource types were also found in Antu country.Changbai Mountain wild Actinidia argutafruits were tetraploid,other multiplicity of species had not been found yet.
