The aimsof this research were to morphologically characterize 27 local genotypes of tulip,to evaluate the genetic variability between them using 32 morphological traits, and to determine their chromosomal number. The results allowed the distinction between the studied genotypes based on the morphological characterization of all vegetative,floral andbulb traits. Results confirmed that the main limiting factor for distribution over the screened regionwas the high above sea level.All genotypes were divided into two main groups, the firstone included genotypes located at 400 - 850 m of altitude, and the second one located between 950 -1450 m. The microscopic analysis results showed that all the studied genotypes were diploid (2n=2x=24 chromosomes). Depending on the results of the morphological characterization and the chromosomal number of local genotypes studied, it can be considered the closest to the specie Tulipaagenensis D.C.

Research summary
هدفت هذه الدراسة إلى توصيف 27 طرازًا محليًا من نبات التوليب في محافظة اللاذقية من الناحية المظهرية وتحديد العدد الصبغي لها. استخدمت الدراسة 32 صفة مظهرية لتحديد التباين الوراثي بين الطرز المختلفة. أظهرت النتائج أن الطرز يمكن تمييزها بناءً على الصفات المظهرية للمجموع الخضري، الزهري، والأبصال. كما أظهرت النتائج أن الطرز المدروسة يمكن تقسيمها إلى مجموعتين رئيسيتين بناءً على ارتفاع مواقع وجودها عن مستوى سطح البحر. المجموعة الأولى تشمل الطرز الموجودة على ارتفاع بين 400 و850 مترًا، بينما تشمل المجموعة الثانية الطرز الموجودة على ارتفاع بين 950 و1450 مترًا. أظهرت الدراسة أيضًا أن جميع الطرز المدروسة ثنائية الصيغة الصبغية (2n=2x=24). بناءً على النتائج، يمكن اعتبار الطرز المحلية المدروسة أقرب ما تكون للنوع Tulipa agenensis. توصي الدراسة بضرورة إجراء مسح جغرافي وبيئي شامل لمناطق انتشار التوليب في سوريا واستخدام معايير وراثية إضافية لتحديد الاختلافات الوراثية بدقة بين الطرز المدروسة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو فهم التنوع الوراثي والمظهري لنبات التوليب في سوريا. ومع ذلك، كان من الممكن تعزيز الدراسة بإدراج المزيد من الطرز من مناطق جغرافية مختلفة لتقديم صورة أكثر شمولية. كما أن استخدام تقنيات تحليل وراثية حديثة مثل التسلسل الجيني الكامل كان يمكن أن يضيف عمقًا أكبر لفهم التباين الوراثي. بالإضافة إلى ذلك، كان من المفيد تضمين تحليل للعوامل البيئية الأخرى التي قد تؤثر على التباين المظهري والوراثي، مثل التربة والمناخ المحلي.

    الهدف الرئيسي هو توصيف 27 طرازًا محليًا من التوليب في محافظة اللاذقية من الناحية المظهرية وتحديد العدد الصبغي لها.

  2. ما هي الصفات المظهرية المستخدمة في الدراسة؟

    استخدمت الدراسة 32 صفة مظهرية لتحديد التباين الوراثي بين الطرز المختلفة، تشمل الصفات المظهرية للمجموع الخضري، الزهري، والأبصال.

  3. كيف تم تقسيم الطرز المدروسة بناءً على ارتفاع مواقع وجودها؟

    تم تقسيم الطرز إلى مجموعتين رئيسيتين: المجموعة الأولى تشمل الطرز الموجودة على ارتفاع بين 400 و850 مترًا، والمجموعة الثانية تشمل الطرز الموجودة على ارتفاع بين 950 و1450 مترًا.

  4. ما هو العدد الصبغي للطرز المدروسة؟

    العدد الصبغي لجميع الطرز المدروسة هو 24 كروموسومًا (2n=2x=24)، مما يعني أنها ثنائية الصيغة الصبغية.

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.
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.
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.
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 research was carried out in the laboratories of the Atomic Energy Commission Molecular Biology and Biotechnology Department in Damascus to study the molecular characterization of five of local and introduced grapes varieties which collected f rom the Pome and Grapevine Research Center in Sweida using 20 primer pairs of SSR.
