Abstract This study was carried out in the Black Sea
region of Turkey between 2001 and 2004. The objective was to develop new kale
(Brassica oleracea var. acephala) variety candidates for fresh
consumption. In the first year, 127 kale populations were collected from
different ecogeographical areas in this region. All populations of native
kale genotypes were examined for morphological characteristics. From the
following observations, 22 types were evaluated as superior using a weighting-based
ranking method. All populations showed a range of 15.9–21.9 cm for leaf length,
10.4–13.2 cm for leaf width, and 0.26–0.35 mm for leaf thickness. Leaf colours
of selected types were dark green and very dark green, except for 61AK01.
In the majority of populations harvest time occurred at 102 days and was
classed as early. Range of the leaf number/plant was between 4.0 and 12.1.
52CA07 had the highest the leaf number/plant. At the end of this research,
11 types were selected as being promising for further breeding efforts. The
other genetic resources were taken for preservation as breeding materials
at Turkey Seed Gene Bank in Izmir-Menemen.
