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.
