The influence of two reproductive pathways: sexual reproduction and vegetative propagation. on the phenotypic values of F1 potato hybrids was analyzed. Population of 150 genotypes obtained after crossing of two Dutch varieties (Cosmos and Van Gogh) was investigated. Investigations were conducted in contemporary net house of Potato Research Center at Guta during two years. Seedlings were investigated in the first year while clones were investigated in the second year. Values of three studied traits (leaf number per plant, total leaf area of plant and tuber yield per plant) differed significantly between F1 seedling and clones. Phenotypic values of the other three studied traits (single leaf area, chlorophyll content in leaves and harvest index) were similar between F1 seedling and clones. It was concluded reproductive pathway had the great influence on some phenotype characteristics of F1 potato hybrids. Surprisely. reproductive pathway had no influence on the relationships between six studied traits. The values of simple correlation coefficients among all six traits were similar in seedlings and clones
