Japanese persimmon (Diospyros kaki Thunb.) cultivars are classified into four types depending on the nature of astringency loss of the fruit. The pollination-constant, non-astringent (PCNA) persimmons lose their astringency on the tree as the fruits de- velop. This PCNA trait is qualitatively inherited and recessive to the other three types, pollination-constant, astringent (PCA), pollination-variant, nonastringent (PVNA), and pollination-variant, astringent (PVA). In fact, crosses among Japanese PCNA cultivars yield only PCNA type in F 1 generation as shown in recent breeding programs at the National Institute of Fruit Tree Science. Despite these previous results, we demonstrated here that non-PCNA (PVNA, PVA, and PCA) type offspring were derived at relatively high rates in the F 1 generation from a cross between ʻLuo Tian Tian Shiʼ, a PCNA acces- sion from China, and the Japanese PCNA cultivar, ʻTaishuʼ, despite the fact that ʻLuo Tian Tian Shiʼ was confirmed to be a true PCNA type by measuring tannin cell size, a principal morphological characteristic to distinguish PCNA cultivars from non-PCNA ones. When segregations of tannin cell size and tannin content in three progenies of the breeding populations derived from Chinese PCNA ʻLuo Tian Tian Shiʼ x Japanese PCNA ʻTaishuʼ, Japanese PCNA ʻShinshuʼ x Japanese PCNA ʻTaishuʼ, and Japanese PVNA (non-PCNA) ʻKurokumaʼ x Japanese PCNA ʻTaishuʼ were investigated, all offspring be- tween Japanese PCNA cultivars contained only small tannin cells and were PCNA types, and those between Japanese PVNA x PCNA cultivars contained only large tannin cells and were non-PCNA types. However, hybrids between ʻLuo Tian Tian Shiʼ and ʻTaishuʼ segregated into populations of small and large tannin cells, indicating that ʻLuo Tian Tian Shiʼ is likely heterozygous for astringency. Therefore, Chinese PCNA ʻLuo Tian Tian Shiʼ should be different from Japanese PCNA cultivars in genetic makeup.
