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).
A field experiment was conducted at two environmentally different locations
(Damascus and Dara'a), to evaluate the performance of 16 barley genotypes
under rainfed conditions during the growing season of 2011-2012 in order to
study in the response
of some quantitative traits and determine the yield under
drought conditions. The experiment was laid out according to the factorial
complete randomized block design with three replicates for each genotype.
Significant genetic variation was found in the response of barley genotypes to
water stress. The performance of all genotypes was significantly superior in the
less dry region (Izra’a-Daraa) compared to the more dry one (Abo jarash-
Damascus) for all the examined parameters. Results revealed that the number
of grains per spike was significantly higher in most lines compared to Arabi
Abiad and Arabi Aswad, and the number of grains per spike was significantly
higher in the line29 (43.17 grain per spike). The number of grains per m2 was
significantly higher in line29,line64, Arabi Abiad and line14 (11177, 10809, 10802,
10744 grains per m2), respectively. The mean grain yield was significantly
higher in the line64, line14 and Arabi Abiad. (479.3, 476 and 443 gram per m-2),
respectively. Harvest index was significantly higher in all lines compared to
Arabi Abiad and Arabi Aswad.
The research was conducted at Abo-Jarash farm, faculty of
agriculture, Damascus university during the two growing season
2011-2012 and 2012-2013 in order to evaluate genetic variability of
some lentils genotypes based on some physiological and
productivity traits associated with drought tolerance. The
experiment was laid out according to factorial randomized complete
block design with three replications.
This study was carried out at the Faculty of Agriculture, Damascus
University, and ACSAD during the year 2001 – 2002 in order to assess the
genetic variability of twenty wheat genotypes for osmotic stress tolerance by
using PEG-6000 as a water str
ess induced tool. This trial aimed to develop
a semi-natural rapid and effective screening technique in which the optimum
induction as well as lethal levels of osmotic stress are well defined .
The results revealed that the treatments –0.4 MPa and –1.5 MPa were the
optimum induction and lethal levels of osmotic stress, respectively.
This research was conducted in Abo Jarash farm (College of Agriculture,
Damascus University) in 2009/2010. Fifteen strains of durum wheat contrived
by ACSAD and ICARDA were studied, the productivity and its main
components were compared with four
certified varieties of durum wheat in
Syria. The experiment was designed in complete randomized block design with
three replicants. The results showed the presence of significant differences
between the strains in most of the studied traits, and the strains derived from
ACSAD were featured in the performance under the experiment condition.
And those strains were characterized by the early heading, and maturity
comparing with the wildly cultivated varieties in Syria and some of them were
super or in grain production as Acsad 1311, Acsad 1327, Acsad 357(3648.36,
2988.75, 2884.80 kg/ha). The results confirmed the importance of the some
components of productivity, weight of thousand grain, number of spikes, And
plant length which were correlated positively with the productivity in unit area.
