Research summary
تُعنى هذه الدراسة بتقييم أداء بعض الطرز الوراثية للعدس (Lens esculenta L.) تحت ظروف الزراعة المطرية والمروية. أُجريت التجارب في مزرعة أبي جرش، كلية الزراعة، جامعة دمشق خلال الموسمين الزراعيين 2011-2012 و2012-2013. هدفت الدراسة إلى تقييم التباين الوراثي لبعض طرز العدس بناءً على بعض الصفات الفسيولوجية والإنتاجية المرتبطة بتحمل الجفاف. أظهرت النتائج تبايناً وراثياً بين الطرز المدروسة، حيث سجلت الطرز كردي، إيبلا، إدلب3، إدلب4 تفوقاً معنوياً في الغلة الحبية تحت ظروف الزراعة المروية. يُعزى هذا التفوق إلى زيادة متوسط وزن الـ100 بذرة، وعدد البذور في النبات، ومحتوى الماء النسبي في الأوراق. كما أظهرت الدراسة أن الطرز التي حافظت على دليل مساحة ورقية عالٍ ومحتوى ماء نسبي مرتفع في الأوراق حققت غلة حبية أعلى. توصي الدراسة باستخدام الطرز الوراثية المتفوقة كآباء في برامج التربية والتحسين الوراثي لتطوير أصناف ذات إنتاجية عالية وأكثر تحملًا للجفاف.
Critical review
تُعد هذه الدراسة مهمة في مجال تحسين إنتاجية العدس تحت ظروف الجفاف، إلا أنها تفتقر إلى تحليل أعمق للعوامل البيئية الأخرى التي قد تؤثر على النتائج مثل نوعية التربة ودرجة الحرارة. كما أن الدراسة ركزت بشكل كبير على الصفات الفسيولوجية والإنتاجية دون التطرق بشكل كافٍ إلى الجوانب الجينية التي قد تساهم في تحمل الجفاف. كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تحليلاً جينياً للطرز الوراثية المدروسة. بالإضافة إلى ذلك، كان من المفيد تضمين توصيات عملية للمزارعين حول كيفية تطبيق النتائج على أرض الواقع.

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 performance of some barley genotypes was evaluated under rain-fed
conditions in Dara'a (Izra'a) during two successive growing seasons (2009-2010/
2010-2011) in order to determine the most relevant physiological traits, which
are genetically as
sociated with drought tolerance and grain yield. The trial was
laid out according to the factorial complete randomized block design, with
three replicates. The leaf area index (LAI) was significantly lower in the wild
relatives compared with the varieties and land races. Relative water content
was significantly higher during the second growing season (87.19%) compared
with the first one (71.57%). Solute leakage was significantly lower during the
second growing season (69.50%) compared with the first growing season
(76.49%). It was noticed that the genotypes which have achieved significantly
higher grain yields, could also maintain significantly higher relative water
content in the leaves, (Acsad176, Acsad1182 and Acsad60), and were superior in
maintaining membrane integrity, and leaf area index, indicating the
importance of such traits in improving drought tolerance and maintaining
production capacity.
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.
A study was carried out in the 2nd agro-ecological zone at the General Commission
for Scientific Agricultural Research/Sirbaya Research Station/Aleppo during the growing
season 2011-2012. The study aimed at evaluating the response of different vari
eties of
lentil to supplemental irrigation. The experiment adopted a split plot design with three
replicates. Two water treatments, supplemental irrigation (R) and rain feed (Ro) were
applied to three varieties of lentil: IDLEB1 (D1), IDLEB1 (D2), and IDLEB1 (D3). The
results showed that R was more significant than Ro at a confidence level 5% for grain, hay
yield, and 100-grain weight. The differences were significant between the varieties that
applied Ro; the most significant of which was D3 for grain and hay yield, and D2 for 100-
grain weight. As for R, the differences were significant for grain yield (the most significant
was D3) and 100-grain weight (the most significant was D2), while there was no
significant difference for hay yield. There was no interaction between water treatment and
the variety in terms of grain yield and 100-grain weight, while it was observed for hay
yield.
The research was carried out at Al-Qamishli Agricultural Research Center, GSAR,
Syira, during the seasons 2011, 2012 and 2013, in order to estimate the effect of
adding different levels of a crude Zeolite (T2-20 tons/ha, T3- 40 tons/ha, in addition
to the control (without adding Zeolite T1), on wheat productivity within a bilateral
crop rotation was followed, consisted of wheat and chickpea, and on the content of
nitrogen, phosphorus and potassium in the surface layer of the soil .The research
was conducted using Complete Randomized Block Design with three replicates.
