This research was carried out in molecular biology laboratory
faculty of agriculture /Damascus University during the agriculture
season 2015-2016, to study the genetic diversity and determine the
degree of genetic similarity among eleven 11 cultiv
ated vetch
(Aleppo, Idleb, Kamishly, Hassekeh, Tartous, Lattakia, Homs,
Hama, Sweida, Damascus,Daraa) by using the technique ISSR.
Morphological and molecular characterization for six seedling genotypes of
Pistachio vera L (V1,V2,V3,V4,V5, and V6) in comparison with the most
commercial and wide spread varieties, Ashoury andWhite batoury was carried
out in Swaida province, sou
thern of Syria. Nuts chemical contents (dry
substance, moisture, total sugar and oil content) for both fresh and dry nuts
weight were also evaluated.
Seedling genotypes showed obvious differences toward the main diagnostic
traits, such as alternate bearing phenomena, the ratio of kernel weight to total
nut weight, split nuts percentage and loss percentage. Genotype V4 was
recognized by some important characters compared with the other genotypes
studied. Cluster analysis was assessed according to the existence or absence of
the most important studying morphological and agronomic indexes. All
genotypes studied and comparative cultivars were clustered into four groups.
RAPD technique was achieved using 25 randomly primers, 19 of which were
polymorphic with an average of polymorphism percentage of (66.47%). The
highest value of genetic similarity (0.81) was between Ashoury and V5
genotype, whereas the lowest value (0.56) was between V3 and V6. Cluster
analysis depending on RAPD data divided the population studied into two main
groups. RAPD unique band was estimated (37 unique band, 21 positive and 16
negative).
It was concluded that RAPD technique can be used efficiently to emphasize,
identify, insure and evaluate the genetic diversity of Pistachio vera.
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).
This investigation was carried out at the Laboratory of Biotechnology at
General Commission for Scientific Agricultural Research (GCSAR), during the
season 2010-2011. The aim of this research was to study the genetic diversity
among twenty individ
ual plants of seven species and to determine the degree of
genetic similarity using the technique ISSR (Inter Simple Sequence Repeats)
and 10 primers were used for this purpose. All primers proved their
effectiveness in showing polymorphism between the studied species, primers
gave a total 195 allele with a polymorphic percentage 100%. The number of
bands for each primer varied from a minimum of 12 bands for the primer
(ISSR-4) to a maximum of 27 bands for the primer (ISSR-862) in an average of
19.5 bands for each primer, cluster analysis and Dendrogram showed the
highest degree of genetic similarity between accession A.leucoclada1 and
A.leucoclada2 (0.64), while it was low between species A.leucoclada3 and
A.glauca2 (0.10). Results showed vast genetic diversity among the studied
species.
This research was conducted to detect the morphological and molecular
differences between golden henbane (Hyoscyamus aureus L) collected from
south Syria. Seeds were collected from six locations, then sterilized and grown
In Vitro. Grown plants we
re described for some morphological characters. The
molecular characterization was carried out using the method of Inter Simple
Sequence Repeats (ISSR) to detect genetic variations. The plants showed
significant (p<0.01) morphological differences among studied locations, Plant
height ranged from 14.97 to 18.97 cm and stem color ranged from red to green.
Trichome density also ranged between medium, high and very high.
Furthermore, significant differences in leaves dimensions were observed
according to the plant geographical location. The main root length ranged from
6.09 to 8.37 cm. Molecular analysis by ISSR produced a total of 56 bands, 49 of
which were polymorphic (87.5%), resulted from using 11 non-specific primers.
A genetic distance dendrogram was drawn. based on the results of genetic
characterization of plant from different locations. The plants collected from
Salkhad separated with a genetic distance of 0.312 while the plants collected
from other locations were grouped together, at the same time, they were
divided into two sub groups, the first group comprised plants collected from
Qalamoun and Dimas regions with a genetic distance of 0.032, whereas sub
group II content Bosra plants which separated clearly from those of Dara' dam
and Wadi Al-Zaidi by a genetic distance of 0.017, These results may indicate a
relationship between genetic characters of this plant species with geographic
distribution.
