SELECTIONS OF SELF-FERTILE OLD PLUM CULTIVARS FROM THE BELGIAN FRUIT GENETIC RESOURCES COLLECTION

Four old plum cultivars were selected from the 144 accessions in an experimental orchard established by Belgium’s State Plant Pathology Station and were re-introduced into the nursery trade.
They were labelled ‘RGF’ cultivars, an acronym for ‘Ressources Génétiques Fruitières’. The orchard has been systematically screened for disease resistance and major agronomic characters.
For 4 selected cultivars, a pollination study was conducted over a period of 3–5 years to determine their degree of self-fertility.
The study showed, in terms of the percentages of fruit-set after self-pollination, a considerable variability between years for some of the cultivars.
Cvs Sainte Catherine and Prune de Prince varied from self-fertile to partly self-fertile, depending upon the trial year, and, therefore, are considered to be partly self-fertile.
Wignon is considered to be self-fertile and Belle de Thuin appeared to be self-sterile.
