SOME RESULTS OF THE PLUM BREEDING PROGRAMME AT THE FRUIT-GROWING RESEARCH INSTITUTE IN PLOVDIV
Until now an F1 hybrid fund was established amounting to 3275 plants of 37 parental combinations. 38 elites of Prunus domestica and one of P. salicina have been bred and propagated for future investigations.
The following cultivars were included in the hybridization as the most appropriate donors Stanley, Green Gage, Pacific, President, Serdika, Scoldus and Renklod Hramovih, all of P. domestica species.
The species P. armeniaca, P. dasycarpa, P. cerasifera and P. ussuriensis were used for the interspecific hybridization, all of these species being in combination with P. domestica.
A total of 42 interspecific hybrids were obtained.
The most efficient proved to be the combination of the plum cultivar Stanley and the Modesto apricot, the hybrids of which were 18 in number.
