هدفت الدراسة إلى تحديد نسبة الفقد في الإنتاج عند بعض أصناف القمح القاسي في سورية، إزاء مرض صدأ أوراق القمح المتسبب عن الفطر Puccinia triticina Eriks، و معرفة إمكانية تأثير صفة الصدأ البطيء في الحد من خطر المرض. نفّذت الدراسة في الموسم الزراعي 2015 في حقول التجارب التابعة لكلية الزراعة في جامعة حلب، و شملت ستة أصناف من القمح القاسي (شام1، شام5، دوما1، شام9، Beltagy وMassine).
The aim of this study is to determine the percentage of loss in yield of some durum wheat varieties against wheat leaf rust, and to identify whether the slow rusting has a positive effect in limiting yield loss. The study was carried out in the fields of experiments at Faculty of Agriculture, Aleppo University, Aleppo, Syria, 2015, included six durum wheat varieties (Cham1, Cham5, Douma1, Cham9, Beltagy and Massine).

A number of diseases attack wheat crop in Syria. Yellow rust or stripe rust
(Puccinia striiformis West f. sp. tritici) is considered the most important rust
disease of wheat in the cool and humid wheat growing area. The disease spread
in all wheat
growing areas in Syria specially in the irrigated and humid area.
To identifey the distribution and severity of the disease during the two seasons
1999-2000 and 2000-2001، field survey have been conducted in 76 fields in the
first season and 73 fields in the second season in different wheat growing area
in Syria.
The banking sector shapes a main backbone of economy in any country, given the great services provided by the economic life in any society, in addition to the significant developmental role play as a motivator and a engine of development wheel, and l
ike all other institutions banks seem subject to the competition element among them in the domain of credit granting.
The significant developments in the financial sector at the level of the world marked by the enormous technological progress in the banking industry, and the introduction of new financial instruments some financial crises, and most of the crises in the financial sector problems were common denominator where the banks, experts attributed this to increased risks, led by banking credit risk arising from credit granting, therefore it was necessary for each bank to put specific controls that guarantee the possibility of increasing granting credit while maintaining risk within acceptable limits, this requires the availability of an efficient system of credit analysis.
Here they sought researcher of this study is to focus on the study of credit made in the Commercial Bank of Syria, which overlook a lot of the important aspects that need to be studied and which may constitute a starting point for risk, Which leads in turn to stumble in the future, the researcher in theoretical section depended on the descriptive approach to what is stated in the most important books and references Banking and Finance, and depended on field study in the practical side to get to know the reality of the studies conducted by the Commercial Bank of Syria before granting loans and advances.
The goal of the researcher of this study to verify the existence of a certified system of credit analysis at the Commercial Bank of Syria, and the efficiency analysis in commercial bank credit to reduce the size of the credit risk associated with the granting of loans.
The most important results lack a holistic system of system credit analysis at the Commercial Bank of Syria, particularly with regard to financial ratios used in the analysis process, the adoption of curriculum diversification to reduce risks associated with the granting of credit, The bank's focus on collateral and personal for the granting of loans, and credit analysis neglects to identify the purpose of the granting of the loan as well as the history of banking transactions for credit applicants with other banks.
The research aimed to identify the current status of wheat in Syria during the period
(2000- 2012), and to study the energy of production and consumption, gap size,
besides self-sufficiency ratio of wheat, as well as to highlight on the average per
capita of the available for consumption, the annual average income per capita, and
the annual population increase. The research also indicated the most important
factors affecting the production and domestic consumption of wheat. The results had
showed that the general trend of total production, cultivated area and productivity
is a descending direction during the studied period. Also, the consumed amount of
wheat during the studied period increased, with an average of (4084.42) thousand
tons annually, while the average of domestic production amounted to about (4008.38)
thousand tons for the same period. Besides the food gap of wheat ranged between
a minimum value at (17.3) thousand tons in 2000, and a maximum value about
1660 thousand tons in 2009, the year in which consumption reached its maximum
value in the time of studied series. The self-sufficiency ranged from (69.04%) in
2009 and (131.03)% in 2007 with an average of about (99.1)% during the period
(2000 - 2012).
Yellow rust caused by Puccinia striiformis f.sp. tritici is one of the most important
disease affecting wheat worldwide. The objective of this study was to evaluate
some morphological and productivity characteristics of durum and soft wheat
collected from different locations of Syria.
A survey to record the genera of nematode associated with wheat in the
south region of Syria was carried out during 2002/01. 600 soil samples were
collected from the rhizosphere of wheat and examined. Nematodes were
extracted, identified and frequ
ency was calculated for each genus. Results
showed that 17 genera of nematode were associated with wheat. These genera
were divided into three groups. The free living nematode consisted of eight
genus, the plant and fungi nematode three genus and the plant parasitic
nematode group contains six genus.
