| Abstract:
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. | |
