The Polymorphic Study of Ten Table Grapes Varieties Using RAPD Method

The polymorphic study of table grapes was performed on ten varieties provided from two resorts grapevine: S.D.E. Cluj and S.D.E. Iai. To achieve this study on grape varieties we used RAPD method. Genetic diversity and relationships between individuals was evaluation on the basis of presence or absence of bands resulting spe cific genetic fingerprinting. In this purpose we tested a total of 22 RAPD primers only 12 were polymorph. We made two rehearsals for each primer, taking into account only visible bands presents in the two rehearsals. The fragments resulted by amplification with polymorph primers have a lengths between 200 and 1500 bp. Notation of bands has been made by reference to DNA marker with 1 the presence of bands and with 0 the absence of bands. On the basis of these results dendrogram was constr ucted .
