PRODUCTION OF CERTIFIED PLANTING MATERIAL FOR BIOLOGICAL FRUIT PRODUCTION FROM BLACKCURRANT

P. Minkov
Basic mother nursery from the blackcurrant cultivars ‘Ometa’, ‘Titania’, ‘Hedda’ and ‘Silvergieters Schwarze’ (Ribes) was put to procedures for biological certification based on complete excluding of mineral fertilizers and use only of permitted means for plant protection. Conversion has started since 2007, and in 2010 a certificate was obtained from the licensed company “Balkan Biocert” for bio-logically certified planting material, with which plantations for biological fruit production can be established. Rooting of mature cuttings from cultivars ‘Ometa’, ‘Titania’, ‘Hedda’ and ‘Silvergieters Schwarze’ took place under the same conditions. The results of the conducted observations showed that the percentage of rooting of the cultivars varied from 70% (‘Hedda’) to 96% (‘Titania’) obtained planting material had acceptable quality.
