JAPANESE PLUMS IN HUNGARY

Blooming phenology, fertilization, frost tolerance and yielding potential of Japanese plum varieties have been observed on several growing sites over several seasons.
Open flowers appear on Japanese plums one week earlier, as a mean, than on European varieties.
In Hungary, all varieties in question are to be considered as self-incompatible because the rate of self-fertility is low and variable.
Blooming periods of most varieties overlap each other, but fruit set is largely dependent on the combination of varieties.
Frost tolerance of Japanese plum varieties is comparable with that of the peach or somewhat better than that during the winter and spring time.
One part of Japanese plum varieties starts fructification early and is a heavy yielder (e.g. ‘Burbank’, ‘Friar’) than other varieties (e.g. ‘Santa Rosa’, ‘Del Rey Sun’). During the last 10 years Japanese plums are sold at relatively high prices on Hungarian supermarkets in the early season as well as in the autumn and winter months.
As a result of our investigations we listed those varieties, which are recommended for commercial production under Hungarian conditions: ‘Angeleno’, ‘Black Amber’, ‘Burbank’, ‘Fortune’, ‘Friar’, ‘Obilnaya’, ‘Shiro1, ‘Sorriso di Primavera’, ‘T. C. Sun’.
