This study aimed to compare the susceptibility of five wheat varieties Eratom, Al-Iz, Rabea, ACSAD and Om-Rabei to infestation by Khapra beetle by estimation of population density of insect phases, population reproduction rate and the loss in germination percentage at two levels of infestation 2 and 4 pairs/ 100 gr. grains and four storage periods 3, 6, 9 and 12 months under natural conditions. Results showed significant differences between varieties. Eratom was the most susceptible variety and the population density, population reproduction rate and loss in germination percentage were 2868.08 individual, 77.61 individual/month and 65.82%, while ACSAD was the least susceptible one and the values were 1004.91 individual, 23.88 individual/month and 47.49% respectively. Also infestation level and storage period had a significant effect on the population density, population reproduction rate and loss in germination percentage.

Research summary
تتناول هذه الدراسة مقاومة خمس أصناف من القمح لخنفساء الكابرا (Trogoderma granarium Everts). تهدف الدراسة إلى مقارنة مدى تعرض أصناف القمح Eratom، Al-Iz، Rabea، ACSAD، وOm-Rabei للإصابة بالخنفساء من خلال تقدير كثافة السكان لمراحل الحشرة، معدل تكاثر السكان، وفقدان نسبة الإنبات عند مستويين من الإصابة (2 و4 أزواج/ 100 غرام من الحبوب) وأربعة فترات تخزين (3، 6، 9، و12 شهرًا) تحت الظروف الطبيعية. أظهرت النتائج فروقات معنوية بين الأصناف، حيث كان صنف Eratom الأكثر عرضة للإصابة، بينما كان صنف ACSAD الأقل عرضة. كما أن مستوى الإصابة وفترة التخزين كان لهما تأثير معنوي على كثافة السكان، معدل التكاثر، وفقدان نسبة الإنبات.
Critical review
دراسة نقدية: تقدم هذه الدراسة معلومات قيمة حول مقاومة أصناف القمح لخنفساء الكابرا، مما يسهم في تحسين استراتيجيات إدارة الآفات في تخزين الحبوب. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة للدراسة. أولاً، قد يكون من المفيد توسيع نطاق الدراسة لتشمل أصناف قمح أخرى من مناطق مختلفة لضمان تعميم النتائج. ثانيًا، لم تتناول الدراسة تأثير العوامل البيئية الأخرى مثل الرطوبة ودرجة الحرارة على نتائج الإصابة، مما قد يؤثر على دقة النتائج. أخيرًا، قد يكون من المفيد تضمين دراسات اقتصادية لتقييم التكلفة والفائدة من استخدام الأصناف المقاومة.

In the present study, the susceptibility of four varities of wheat Maxipak 65, M221×M24, Saberbek and Condoras in addition to the hybrid F4 (from the hybridization of Maxipak-65 with M221×M24 for four successive generation) against khapra beetle d uring storage was estimated. The population growth of the pest and percentage loss due to pest infestation were taken as criteria for measuring resistance the against insect. The study indicate that the hybrid F4 was the best in productivity and early in production which are favorable characters but contrarily it was highest susceptibility toward the insect infestation. When the insect reared on the hybrid F4, appeared the highest population density and at the same time the infestation caused in the highest loss weight percentage. On the other hand the Maxipak-65 variety showed the lowest population density of the pest and the lowest loss weight percentage due to infestation than the other varieties and hybrid F4. This result indicates that resistant character depressed during inbreeding during F4 hybrid production in compared to parents therefore it must be early consumed to prevent the infestation by the insect studied.
Five improved genotypes of durum wheat (T. turgidum var. durum) (Lahn, Cham1, Gezira17, Bouhouth 5, and Acsad 65) were planted under the conditions of the agricultural region (Bouka) of the Faculty of Agriculture- Tishreen University during the ag ricultural year 2002-2003, with a split-plot arrangement to study the effects of flag leaf removal on grain yield and its components.The genotypes differed significantly in flag leaf area, stomatal frequency, yield parameters and protein content. Flag leaf removal significantly reduced plant height, number of spikelets/ spike, number of grains/ spike, 1000 kernels weight and grain yield, while grain protein content significantly increased. There was a positive correlation between the flag leaf area and 1000- kernels weight and grain yield, but protein content was negatively correlated with grain yield.
This research work was carried out in the nursery field of the Faculty of AGgriculture in Tishreen Univesity during the spring growing season of 2012, it involved studying some chemical characteristics of potato tubers of Five newly introduced vari eties of potato ( Atlas, Bureen, Bomba, Rumba and Orla), in comparision with Spunta variety as a control. It was showed that the hieghest large tuber were recorded in Atlas ,Burren and Bomba. Bomba variety showed hieghest standards tubers (7.8 Kg/ m2). It was showed also the hieghest dry matter (DM=20.5 %), and Ash content (1.01%) in tubers, were recorded in Rumba variety. Bureen and Spunta varieties showed hieghest values of starch contents (14.5 % and 14.4%) respectively. While Vitamin C (VC ( , was encountered ( 19.36, 17.6, and 17.6 mg / 100g) for Rumba, Spunta and Bureen respectively. Also, the highest values for protein content (1%) and the soluble solid (5%) in tubers were found in Rumba variety.
This study was carried out at AL-Rasheedia Agricultural Research Station ,Ninevah, to evaluate five radish cultivars, during fall seasons (1997-1998) and (1998-1999) . Results showed significant differences among the different cultivars. The cult ivar Black (Rabeea) was superior to other cultivars in number of leaves/ plant, root diameter, weight, and total yield /donum, which were 11.81, 9.22 (cm), 382.91 (gram), and 11.67 ton/ donum respectivelly. The April Cross cultivar gave the highest root length and foliar weight. Significant correlation was observed between cultivars. Yield was significantly correlated with root weight, number of leaves per plant and foliar weight. The root weight was positively correlated with its diameter, and number of leaves per plant.
To determine the susceptibility of some olive varieties to the disease of eye peacock, We studied the development of eye peacock disease on 3 varieties (Khadairy - Zorzalina - Frontoio. The percentage of infected leaves and the severity of infection were estimated during spring and autumn months, the maximum period of the spread of the disease.
