Genetic diversity of some mediterranean populations of the cultivated alfalfa (Medicago sativa L.) using ISSR markers

Abstract

The genetic diversity within 29 populations, when 15 populations are local originating in the Tunisian south and 12 introduced of Italy, Austerely, France and Morocco, was analysed by ISSR markers (Inter Simple Repeat sequence). The genetic similarity between these various populations is estimated by the index of Rogers and Tanimoto. Genetic diversity is analyzed by one statistical procedure: hierarchical classification. The total number of bands varied between the various populations from 9-16. The percentage of total polymorphism is about 60%. Four large groups were obtained. © 2008 Asian Network for Scientific Information.
