Shrubs were propagated by cuttings and planted in 2000 at the Research Station of the Horticultural Department of Agricultural Faculty of Gaziosmanpasa University, Tokat, Turkey. Fruit weight, fruit diameter, fruit length, fruit flesh percentage and seed weight of genotypes belonging Rosa dumalis and Rosa jundzillii were investigated in the study. Fruit samples were picked up weekly from full flowering to optimal harvest time for measurement and weighing. As a result, fruit development characteristics of species measured exhibited single sigmoidal curve except seed weights. In general, developing of measured properties were fast until last 3-4 weeks, then became stable or slightly decreased. Results obtained in 2011 were higher than the results obtained in 2010 in both genotypes.
