DNA fingerprint analysis of genetic relatedness between rose genotypes, using humanderived minisatellite probes, correctly reflected relationships within and between categories of rose plants. Nearly identical DNA fingerprint patterns were observed for cultivars 'Dick Koster' and its two sports. A high level of similarity was detected between genotypes of the hybrid tea category while a low lev...

The article presents the results of evaluation eleven Scots rose cultivars in northern part Ukraine due to its severe winter conditions. A range variations regarding bloom colour, size, type, flowering incidence, plant size was noticed. showed decorative value and considerable frost resistance varieties ‘Double White’, ‘Dunwich Rose’, ‘Frühlingsduft’, ‘Frühlingsgold’, ‘Frühlingsmorgen’, ‘Karl F...

The effects of sodium chloride (NaCl) salinity (control; canal water with 0.4 dS m-1), 2.5 dSm-1, 5.0 dS m-1, 7.5 dS m-1 and 10.0 dS m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (Rosa hybrida L.) cultivars viz. ‘Kardinal’, ‘Angelique’ and ‘Gold Medal’ were studied to achieve better management, quality product...

Cultivar of roses (Rosa spp.) has been grown in greenhouses in Qazvin region of Iran for local markets. Agrobacterium tumefaciens strains were isolated and identified from six different samples of roses plants imported from the Netherland to Iran. During August and September of 2012, nearly 2-5% of rose plants in two different greenhouses in the province of Qazvin were observed with crown gall ...

Aroma is an important quality characteristic in Muscat grapes and constitutes a major concern for viticulturist and grapevine breeders. For this reason, Muscat aroma variability was characterised in a segregating progeny and in a collection of table grapes, to assess the usefulness of the presence or absence of rose oxide for predicting Muscat genotypes. Simple tasting and an analysis of free a...

in this research, the isolated microspore culture system in 15 rose cultivars was tested. in the first experiment, the effect of rose cultivars on microspore viability and multicellular formation was examined. results showed that the most multicellular structures obtained in ‘apollo’, ‘amarosa’, ‘majic’, ‘candy’, ‘exotic’ and ‘velvet’ varieties. in the second experiment, the effect of various i...
