Abstract

This study was carried out between 2013-2017  years to determine the local names, general
systematic characteristics, group characteristics, genotype number,
distinguishing characteristics, ecological requirements and economic importance
of blackish roses in Turkey. "Blackish roses" are a term used for the
first time as a group name for roses that are black and close flower colors. It
refers black and its allied roses. The studied plant materials were obtained
from GUL Herbarium and Botanical Garden at SüleymanDemirel University. Always
blooming roses in Turkey are generally R. odorata; and in small amounts to R.
borboniana and R. chinensis species. The genotype
number of them is around 20 in Türkiye. Five of these; Bursa (Kestel), Isparta
(Atabey) and Şanlıurfa (Halfeti) are in high importance commercially and as
local genotypes. When looked at the growing environments and spreading areas of
black roses; light intensity, number of sunny days in year, and high
temperatures are becoming important criteria. For this reason, they were
considered as long day plants. Southeast Anatolian region meets the best
ecological demands of these roses. This area is followed by the Mediterranean
and Aegean regions. Black Sea and Thrace are the least suitable geographical
areas. Considering the distribution areas and ecological requirements; the gene
center of blackish roses was estimated as the Southeast Anatolian region and
its environs. Successful rooting of stem steel in perlite environment is 15%
and 5% in soil. The caring and growing of these roses is more difficult than
others. The main reason for that is the ecological demands can not be met
adequately by any regions, except for the Southeastern Anatolia region of
Turkey. In this study; three hypotheses have been proposed about blackish
roses.
