Development of genetic improvement in Chinese PCNA persimmon

A series of PCNA persimmon originated in China(termed Chinese PCNA persimmon or CPC-NA),distributed in Luotian and Macheng of Hubei province mainly,is a rare germplasm of Diospyros Linn. in the world. There are two important and valuable characteristic for PCNA genetic improvement.One is that CPCNA were evolved independently with PCNA persimmon originated in Japan(termed Japa-nese PCNA persimmon or JPCNA),and the other is that the natural deastringency trait of CPCNA wascontrolled by a single dominant gene locus. Here,on the basis of reviewing the achievement of genetic im-provement and breeding in JPCNA briefly,we focus on the inheritance of natural astringency-loss andearly screening for hybrid population in CPCNA. At last,we propose a comprehensive summary on the ge-netic improvement system for CPCNA based on the recent research results.
