Selected growth parameters, phenology and economic properties of different varieties and genotypes of Cydonia oblonga, Hyppophae rhamnoides, Cornus mas, and Lonicera caerulea subsp. edulis were evaluated. Most of the seedlings originated from a Czech gene bank, some varieties of honeysuckle were from abroad. Experimental plots were established using strip planting, the trees were evaluated during 1-5 years. The measured values varied considerably according to the genotype and year. In quince for example, the size of the crown after five years of cultivation varied from 2.3 to 5.7 cubic m, big differences were found also in cold resistance and fruit yield, the most productive variety having been Blanar. Sea buckthorn varieties differed in their growth, shrub shape and fruit production, the most interesting varieties were Leicora and Buchlovicky. Cornelian cherry varieties showed a considerable variability in their growth, fruit weight, dimensions and production. The biggest fruits (4.85 g) and yields were produced by the variety Vysegorodskij. The differences in honeysuckle growth depended on the growth period, harvest data having been in direct proportion to the size of the shrub. The highest dry matter concentrations (determined refractometrically) were found in the varieties Tomicka and Nymfa.
