The proposed approaches to the integrated decorativeness assessment of climbing garden roses functional group are based on cultivars’ biological characteristics in the Russian humid subtropics. In order to assess the decorativeness in cultivar samples, the scale of gradation characteristics was developed (with conversion factors of importance) for this group of climbing roses, i.e. the degree of branching, foliage, bud form, flower colour (intensity), flower form, fragrance intensity, flower size, flowering abundance, inflorescence quality, the ability of bush to self-cleaning and vulnerability to fungal diseases and damaging pests. The proposed assessment methodology allows us to objectively divide cultivars into promising, medium-promising, low-promising and unpromising ones for further cultivation in the given region. Testing on model cultivars that differ in resistance in the culture showed the effectiveness of the proposed assessment criteria.
