Abstract<\/strong><\/p>\n

Morphological characterization was carried out at Abu-Jarash Farm and Biotechnology Laboratory, Faculty of Agriculture, Damascus University during 2008-2010. Twenty samples belong to ten wild species and a cultivated one (control) were planted in randomized complete design (RCD).
\nThe results showed that the control species M. sativa<\/em> was superior to all species in germination earliness, however, the species M. truncatula<\/em>, M. minima<\/em>, M. turbinata<\/em> and M. orbicularis<\/em> were superior in delay flowering; all species superior in branching number except M. truncatula<\/em>; M. scutellata<\/em> and M. orbicularis<\/em> superior in number of leaves per plant; M. minima<\/em>, M. polymorpha<\/em>, M. scutellata<\/em>, M. orbicularis<\/em> in flower stalks number; M. orbicularis<\/em> in pods number. All species were superior in delay of total maturity except the M. polymorpha.
\nPositively significant correlations appeared between most of the studied characteristics. Molecular investigation revealed that all the primers have effectiveness in showing polymorphism, and they gave a total of 92 alleles with a polymorphic percentage of 100%. The number of bands for each primer varied from minimum 5 bands for the primer (ISSR34) to maximum 21 bands for the primer (ISSR-41) on average of 11.5 bands for each primer.
\nCluster analysis of morphological characterization showed siginificant similarity between M. rotata<\/em> and M. polymorpha<\/em>, and between M. scutellata<\/em> and M. turbinate<\/em>, and higher differentiation between M. orbicularis<\/em> and both M. rotate<\/em> and M. intertexta<\/em>, and that was confirmed by the molecular study which showed the highest degree of genetic similarity between M. rotata<\/em> and M.\u00a0polymorpha<\/em> (0.77), followed by species M. sativa<\/em> and M. truncatula<\/em> (0.73); M. scutellata<\/em> and M. turbinata<\/em> (0.71), while it was low between M. orbicularis<\/em> and both\u00a0 M. rotata<\/em> and M. intertexta<\/em> (0.43). The results showed vast genetic diversity among the genus Medicago in Syria.<\/p>\n","protected":false},"excerpt":{"rendered":"
