OBTAINING NEW "PCNA" CULTIVARS OF ORIENTAL PERSIMMON

E. Bellini, S. Villa, G. Giannelli
The renewed interest in persimmon growing in Italy and the neccesity of distributing new cultivars and rootstocks which are better adapted to Italian agronomic and commercial needs is presented here. We refer to the persimmon genetic improvement program (Diospyros kaki L.) being conducted in Florence since 1971 for the production of valuable cultivars of the PCNA group (Pollination Constant Not Astringent).

Studies on the heredity of several genetic characteristics have been conducted on seedlings obtained from different cross-bred combinations made in 1981, 1985 and 1986. These characteristics included sex distribution, the flowering process, flesh astringency, ripening period, fruit size and shape, and skin color.

Finally tree valuable selections are described with particular attention given to desirable characteristics of the PCNA type fruit which are fully compatible with Diospyros lotus and only slightly subject to fruit splitting.
