Abstract:
20 populations of kale (B. oleracea var. acephala L.) selected from 127 populations for fresh consumption terms of yield and leaf quality characteristics as superior types using weight-based ranking method from the Black Sea Region of Turkey were evaluated at the DNA level using randomly amplified polymorphic DNA (RAPD) markers compared to some morphological characters. The 7 primers selected from 100 decamers used generated 110 bands, of which 60 (54.5%) were polymorphic. Jaccard's genetic distances were calculated and dendogram was generated using the UPGMA algorithm. The dendogram obtained were classified into three main groups and four subgroups. The accessions showed a limited clustering in compare to morphological characters such as the number of leaf, leaf intentation of the margin, leaf and midrib color and thickness of midrib than geographical characteristics. Leaf color and midrib thickness characters clustered in the same group as OR49 and G18 accessions; S20, G6 and OR37 accessions, respectively.
