MORPHO-AGRONOMICAL AND GENETIC CHARACTERIZATION OF TWO TRADITIONAL APULIAN BRASSICA CROPS: CIMA DI RAPA (B. RAPA SUBSP. SYLVESTRIS) AND CAVOLO RICCIO (B. OLERACEA VAR. ACEPHALA)

"Cima di rapa" and "cavolo riccio" are two typical Apulian brassica vegetables with highnutritional values, used for several traditional recipes and considered as local heritage. "Cima dirapa" is largely cultivated occurring with several landraces of significant economic importance. Onthe contrary, "cavolo riccio" is a secondary crop, grown in a few peri-urban vegetable gardens inthe metropolitan area of Bari and, recently, it has been mentioned as one of typical vegetable at riskof genetic erosion.The aim of the present work has been to establish a germplasm collection of the two crops, inorder to preserve their genetic variation and, for the first time, to characterize the two crops at themolecular level. On this purpose, morpho-agronomic and molecular data have been recorded on 50accessions of "Cima di rapa" and 19 of "cavolo riccio" were performed. Furthermore, all entrieswere evaluates their yield performances.Genotyping by highly informative simple sequence repeat (SSR) molecular markershighlighted significant patterns of molecular variation among accessions. Polymorphic data wereused to carry out principal component analysis and obtain dendrograms of genetic similarity.
