The pomological classification recognizes four groups:
PCA Group (Pollination constant astringent)
The fruit pulp is not influenced by pollination. The fruit is unedible when harvested, and must become mushy to be traded and eaten, which makes it difficult to handle. Known cultivars are 'Costata' and 'Lycopersicon' in Italy, and 'Hachiya' (conical), 'Tamopan' and 'Tane-nashi' (spherical) in California.
PCNA Group (Pollination constant non astringent)
The fruit is not astringent (even if seedless), and can be eaten when still crisp, as an apple. Israel sells it as 'Sharon fruit', and it is known in French as kaki-pomme. A common cultivar is 'Fuyu' or 'Fuyugaki'.
PVA Group (Pollination variable astringent)
Parthenocarpic fruits, or fruits with few seeds, have a pale and astringent pulp. Pollinated fruits with many seeds have a pulp which turns brown and loses its astringence. Cultivated in Italy ('Kaki Tipo') and California ('Hyakume', 'Okame', 'Yemon', 'Yeddo-ichi'). Commercial names often refer to chocolate, cinnamon or brown sugar.
PVNA Group (Pollination variable non astringent)
The fruit remains astringent. 'Aizumishirazu', 'Hiratanenashi'
