INVESTIGATION OF THE INHERITANCE IN THE PLUM AND PRUNE PROGENIES

The plums and prunes in Yugoslavia originate from centuries ago. They become the most important decidious fruits, on the South-East of Europe (Yugoslavia, Rumania and Bulgaria) under the very convenient ecological conditions.

Yugoslavia is on the first place in the world in number of the plum and prune trees (81.200.000) as well as in production (666.100 tons, average for 1956–1965). Meanwhile, yield per trees is no high and list of the cultivars is pretty short.

Considering the notable position of the plums and prunes in fruit growing of Yugoslavia, the investigations of this culture have been carried out from 1947 up to day. Special attention was paid on the selection within cultivars and breeding.

Breeding in plums and prunes is at present being conducted mainly to produce cultivars free from the faults recognized in the leading cultivar Pozegaca (Yugoslavian prune, Madzarka, Hungarian prune). The latter has relatively too small fruits, mature too late and is not fully satisfactory in vigour or in resistance to cold, drought or diseases (Prunus virus 7, Polystigma rubrum and Puccinia pruni spinosae). The aim of plum and prune breeding at Fruit Research Institute, Cacak, is to try to overcome these defects.

A great deal of raised plum and prune seedlings are already in bearing stage, so thus we have been in the position to make analyses of inheritance of some more important pomological characters.
