Abstract

In order to evaluate the cytogenetic, 36 species were collected berries of Iranian natural areas, using squash technique meristem were studied. The study in Nature with 84, 56, 42, 28 diploid chromosomes, tetraploid, triploid and hexaploid and type of metacentric chromosomes, submetacentric and rare Stumble centric and satellites were significant. The average size of the top ten appropriate metaphase chromosome number and karyotype of each sample and standards for the populations M.rubra and Morus alba separately prepared and chromosomes parameters such as length of chromosomes, long arm, short arm, over the short arm completely, the ratio of long to short arm and chromosomal index was measured. The results showed that populations of species, Morus alba and M.rubra the chromosomes in Geneva M.rubra 96/11 Μμ sample types were calculated. Cluster analysis method "Ward" could total 12 species in Euclidean distance to the three groups, the maximum Euclidean distance of M.rubra of Kermanshah scene and the lowest Euclidean distance between Morus alba species in two areas of Tehran province (Kan and Barqan), accordingly species that are in a similar karyotype and are therefore used in crosses interspecific and can also be used to widen the genetic diversity in the gene pool.
