| Abstract:
Phenological, morphological, and pomological characteristics were evaluated during 1996-2000 in a total of 19 species and 3 microspecies. The plant material was obtained from the Soroksár Botanical Garden, the Szigetcsép Research Station of our Faculty, and from the surroundings of Szentendre in the Budapest area. In addition to the native rose species, some naturalized species were also included. Rosa inodora (syn. R. elliptica) and R. zalana were the most valuable species according to our results. Besides their large fruits with desirable contents, bush shape is suitable for cultivation and they can grow well also in dryer habitats. Other species worthy of attention are R. blanda with high fruit flesh ratio and vitamin C content, R. corymbifera with relative large fruits and suitable bush shape, R. deseglisei with conspicuous mineral contents and R. micrantha which is rich in both macro- and micro-elements. Valuable traits were found also in R. pimpinellifolia with colourful juice, high fruit flesh ratio and high carbohydrate content, R. rubiginosa with excellent fruit yield and high vitamin C content, and R. × vetvickae with prominent vitamin C content. Rosa villosa subsp. sancti-andreae proved to have the largest fruits, with a high proportion of flesh, and high contents of vitamin C and carbohydrates. The investigated microspecies in the R. canina group also have many promising pomological characteristics. | |
