Abstract:
Although southern Poland supports a very limited production of apricots, there has been sufficient interest to develop hardier types. The present active breeding program was started by K. Somorowski in 1952 who planted 1500 seeds of western varieties. This resulted in a population of 1200, one half of which were small-fruited, typical of the wild type, whereas the others approached commercial size. Only 30% survived the severe winter of 1955-56. By the fourth year, only 6% of this group survived, but bore no fruit. Final selection resulted in 18 seedlings that were rather hardy and bore large fruit. After the 1962-63 winter, only 3 remained, the best of which was killed with herbicides.
