The research aimed to evaluate the genetic diversity and the genetic
relationship between 16 Hordeum vulgare genotypes (variaties and new lines),
using SSR markers. 32 primer pairs were used in the analysis, five of them
amplified primers monomorp
hic alleles, while the remaining primers detected
different alleles. A total of 126 polymorphic alleles were revealed by the 27
primer pairs. The number of different alleles detected on alocus ranged from 2
to 11with a mean of 4.66 alleles per locus. The polymorphic information content
(PIC) values ranged from 0.21 to 0.88 with a mean value of 0.49, and the gene
diversity ranged from 0.23 to 0.89 with a mean value of 0.53.The dendrogram
was established using SSR data clustered into three major groups. The smallest
genetic relationship was observed between line39 and line38 . The results proved
the efficiency of SSR markers in the estimation of genetic diversity and in the
clustering of the barley genotypes in Syria.
The research was executed in Biotechnology Lab (Faculty of
Agriculture – Damascus University), during the season 2016.
Sixteen genotypes of Sunflower Oil were planted to study the
genetic diversity among these genotypes and to determine the
degree of genetic Agreement using the technique SSR (Simple
Sequence Repeats).
