STUDY OF THE VARIABILITY OF SOME FRUIT PARAMETERS IN ROSA CANINA L. GENOTYPES FROM SEVERAL LOCAL POPULATIONS IN BAC U, NEAM AND VRANCEA COUNTIESAbstract: There were studied 36 genotypes of Rosa canina L. belonging to 25 native populations from the counties ofBac u, Neam and Vrancea. The analyzed genotypes displayed a high variability of fruit density/individual (shrub), andalso of the shape, size, colour and biomass, and of the content of vitamin C in fruits. There were identified genotypes ofgreat perspective in this species’ amelioration as it concerns the fruit density/plant, a lower density of stem prickles, thefresh biomass/hip, and the content of vitamin C in the ripe fruits.
