This study aimed at checking the stability of some mutant lines from soybean varieties in different locations and to select the best performing lines in each location. These lines 15 were selected according to previous experiments as being early maturing and/or that yield higher than the control. The study lasted three years, the experiment plants were grown in 3 locations: Raqa, Idleb and Lattakia. The experiment was designed as RCBD with 3 replicates for each variety. Results showed significant difference between lines, Locations and year in both earliness and yield, A significant interaction was realized between (line X location) and (line X year) for earliness and yield. For earliness (line X year) was not significant. The reverse situation was realized for yield. Location. X year of yield and earliness was significant. Earliness was correlated positively with all characters (except for 100-seed-weight). Yield was positively and significantly correlated with characters of all lines. Three lines with higher yield than the control (142.61%) and same maturity time were selected.

Research summary
تهدف هذه الدراسة إلى التحقق من استقرار بعض السلالات الطافرة من أصناف فول الصويا في مواقع مختلفة واختيار أفضل السلالات أداءً في كل موقع. تم اختيار 15 سلالة بناءً على تجارب سابقة لكونها مبكرة النضج أو ذات إنتاجية أعلى من الشاهد. استمرت الدراسة لمدة ثلاث سنوات، حيث زُرعت النباتات التجريبية في ثلاثة مواقع: الرقة، إدلب، واللاذقية. تم تصميم التجربة بنظام القطاعات العشوائية الكاملة (RCBD) بثلاث مكررات لكل صنف. أظهرت النتائج اختلافات معنوية بين السلالات والمواقع والسنوات في كل من النضج والإنتاجية، وتم تحقيق تفاعل معنوي بين (السلالة × الموقع) و(السلالة × السنة) للنضج والإنتاجية. كان هناك ارتباط إيجابي بين النضج وجميع الصفات (باستثناء وزن 100 بذرة). كانت الإنتاجية مرتبطة إيجابياً ومعنوياً بصفات جميع السلالات. تم اختيار ثلاث سلالات ذات إنتاجية أعلى من الشاهد (142.61%) ووقت نضج مماثل.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين إنتاجية فول الصويا وتطوير سلالات جديدة مبكرة النضج. ومع ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تم تضمين المزيد من المواقع المختلفة لتقييم استقرار السلالات في ظروف بيئية متنوعة. كما أن الدراسة لم تتناول بشكل كافٍ تأثير العوامل البيئية الأخرى مثل التربة والمناخ على أداء السلالات. بالإضافة إلى ذلك، كان من الممكن أن تكون النتائج أكثر دقة إذا تم استخدام تقنيات تحليل بيانات أكثر تطوراً مثل النماذج الخطية المختلطة.

The present study was conducted at the First of May Station belongs to the General Commission For Scientific Agricultural Research (GCSAR) at Damascus during 2011 and 2012 growing seasons to estimate gene action, heritability, genotypic and phenot ypic coefficient variations (GCV, PCV) and genetic advance for two crosses of soybean. The five population (P1, P2, F1, F2, F3) of each cross were grown in a randomized complete block design (RCBD) with three replications in order to evaluate oil and protein contents and seed yield traits. Results of mean square analysis showed significant differences (p<0.05) among mean values of the five populations for all studied traits between the populations of each cross. The second cross achieved high broad and narrow sense heritability (66%, 44%) for protein content, high value of phenotypic and genotypic variations in seed yield in the second cross achieved (18.03,17.30) and high value of expected genetic advance was obtained 11.09%. In most traits, epistasis of the dominance × dominance type of gene action occupied the first rank in order of importance in controlling inheritance of the evaluate traits in both crosses indicating the importance of selection in late segregating generations to improve these traits. These findings are supported by high values of heritability, which was related with low to moderate expected genetic advance in two crosses.
Eleven genotypes of Bread Wheat (Triticum aestivum L.) were tested at three diverse locations in the Syrian Coast during the 2015-2016 season under rain-fed conditions to assess these genotypes and to study the Genotypes x Environments Interactions , and yield stability across environments using 5 statistical measures of stability:{ X¯i, bi, and i according to Eberhart and Russell (1966), Stability Variance Index (2 i) according to Wricke and Weber (1980), Ecovalance Stability Index (Wi) according to Wricke (1962)}. Genetic material included 5 promising lines and 6 local varieties (provided by ACSAD and GCSAR).The experiment was designed using randomized complete block design with three replications, statistical data analysis was done, and least significant difference (L.S.D) test at 5% was applied for comparison of means. Significant differences were observed among bread wheat genotypes for grain yield (ton/ha), combined analysis of variance of grain yield across the three environments showed significant mean squares due to genotypes, environments and genotypes x environments interaction, suggesting differential responses of genotypes across studied environments and validity of stability analysis. Stability analysis for grain yield revealed that; the promising line ACSAD-1147 and Doma6 were more stable than other genotypes. Due to they had superior ranks for both average yield over environments and yield stability, which reveals the importance of these genotypes to reach varieties that combine relatively high yield and better stability in any future breeding programs.
Isoflavones occurring in soybean seed have a positive effect on the health of humans, especially in cancer prevention. This positive impact may be a result of their antioxidant properties, estrogenic activity, or a combination of both mechanisms. The purpose of this study was to quantify and compare levels of three major isoflavones in soybean seeds from three sources (Alghab area, Faculty of Agriculture, imported from China).
This study was carried out in cooperation between the Faculty of Agriculture, Damascus University and the General Commission for Scientific Agricultural Research (GCSAR) in Karahta station of field crops researches during two growing seasons (2003 -04 & 2004-05). Four local improved barley lines and cultivars (female parents) were crossed with five exotic lines and cultivars (male parents) using line × tester method. The crosses were grown along with their parents in a randomized complete block design (RCBD) with three replications to estimate general combining ability (GCA), specific combining ability(SCA) and both mid and high parent heterosis for number of spikes per plant, number of grains per spike, thousand kernel weight, and grain yield per plant.
This research was carried out during the agricultural season 2014 in the Buqai'a plain in west of Homs governorate, to study the effect of several systems for intercropping on Corn crop (Zea mays L.( and Soybean crop (Glycine max L.): (Zea mays li ne : Soybean line) (Zea mays line : Two Soybean lines) (Two Zea mays lines + Soybean line) ( Two Zea mays lines + Two soybean lines) (Single Zea mays crop), (Single soybean crop).
