摘  要:
采用25 个随机引物对中日两国原产完全甜柿种质的RAPD 分析结果表明: (1)供试中国甜柿和日本甜柿是相对独立分化的两个居群, 中国甜柿的遗传多样性更为丰富; (2)在供试中国甜柿中, ‘罗田甜柿’的5 个单株间的遗传组成的差异较小, 但与其它湖北甜柿和湘西甜柿间的差异较大; (3) ‘铜盆柿’与湖北甜柿间的相似指数较高, 说明二者有某种亲缘关系; (4) 湘西甜柿与供试日本甜柿间的亲缘关系较近, 说明其可能来自日本或是与日本甜柿的起源有关。

摘  要:
RAPD analysis of China and Japan native nonastringent persimmon using 25 random primers were studied.The results showed:(1)China native nonastringent persimmon experimented in the study evoluted indepardently of the Japan native nonastringent persimmon,having more abundant genetic deversity;(2)Among the germplasms of China native nonastringent persimmon,the genetic background of 5 strains of‘Luotian tianshi’,which are mainly distributed over the northwest of Hubei province,is particulary similar,but obviously different from‘Luotian tianshi’and other Hubei native nonastringent persimmon and Xiangxi tianshi,that is mainly distributed over the Hunan privincial;(3)The similarity index value of‘Tongpenshi’and Hubei native nonastringent persi mmon is near,it may suggest somewhat phylogenetic relationship between them;(4)Xiangxi tianshi is close to Japan native nonastringent persimmon in the similarity index value,which may infer that Xiangxi tianshi was from Japan or is a original material of Japan native nonastrngent persimmon.
