ُنفذ البحث في موقعين متباينين بيئياً تابعين لمركز بحوث درعا، الهيئة العامـة للبحـوث العلميـة الزراعية خلال الموسم 2011-2012 ،زرِع 13 طرازاً وراثياً من البازلاء الخضراء في تجربة بتصميم قطاعات عشوائية كاملة بثلاثة مكررات. في هذا البحث درس أداء الطرز المختبرة لـ 10 صفات كميـة مهمة، و قُدر معامل الارتباط الوراثي و المظهري بين أزواج هذه الصفات. أظهرت النتائج وجود تباينـات معنوية بين الطرز المدروسة و للصفات جميعها في كلا الموقعين، و كشفت دراسة الارتبـاط أن تقـديرات معامل الارتباط الوراثي كانت بشكلٍ عام أعلى من القيم المقابلة لها على المستوى المظهري، كما لـوحظ اختلاف في قيم معاملات الارتباط و اتجاهها بكلا مستوييه بين أزواج الصفات المدروسة باختلاف موقـع الدراسة. أظهرت صفة غلّة القرون الخضراء ارتباطاً موجباً ذا دلالة إحصائية و علـى كـلا المـستويين الوراثي و المظهري بصفات عرض القرن، دليل الحصاد و وزن عشرة قرون خضراء في موقـع جلـين، و بصفات طول القرن، و عرض القرن، و عدد القرون/نبات و وزن عـشرة قـرون خـضراء فـي موقـع السماقيات.
This research was conducted at two distinct environmentally locations, Jellien and Al-Somakiate belong to Dara'a Research Center, the General Commission for Scientific Agricultural Research during 2011-2012 growing season. 13 garden pea genotypes were planted according to a randomized complete block design with three replicates to study the performance of these genotypes for 10 important quantitative traits and to detrmine the genotypic and phenotypic coefficients of correlation between the traits studied. Results showed that there were significant differences among the genotypes for all traits studied at both distict locations. The genotypic correlation coefficients were higher than corresponding phenotypic correlations, in addition, the value and direction of correlation coefficient at both levels were different from location to another. Green pod yield showed positive and significant correlations with pod width, harvest index and 10-green pod weight at Jellien location, and with pod length, pod width, pods number per plant and 10-green pod weight at Al-Somakiate location.

A field study has been carried out in order to know the important species
belonging to the family Syrphidae Diptera . in some field in Ezraa & jellien of
Daraa governorate during the period 1/3 /2003 till 30/8/2003 .
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.
Nine Syrian cotton genotypes i.e. Aleppo 33/1, Aleppo 118, Aleppo 90, Aleppo 40,
Aleppo 124 Rakka5, Deir Al-Zour 22, Line 106 and Rusafa, were used for statistical
and genetic analysis for productivity and some chemical indicators of seeds:
Lint p
ercentage%, cotton weight per plant/g, percent of oil in seeds and pulp, percent
of protein in seeds and pulp, percent of humidity in seeds and pulp, to explore
the potentiality of the genotypes in the studied region, and to establish a program
for the production of cotton and seeds, also to determine the selective indecies to be
used to improve cotton productivity and seed components, using randomized complete
block design with three replications. The experiment was conducted in Salhab
village, Al-Ghab region, Hama governorate, Syria, during 2015 season.
The study was carried out at AL-Rasheedia Agricultural Research Station,
Nineveh, to evaluate nine introduce pea cultivars for dry production, during
two fall growing seasons of (2000- 2001) and (2001- 2002).
The results showed that the cultivar,
P.S.510571 gave the highest value in
plant length at both two seasons. The cultivar, M.G.102703 was superior in the
number of pods per plant, pod weight, weight of 1000 seeds, and gave higher
yield of dry production per unit area (722.5 and 780.2 kg/ donum) for the two
seasons, respectively.
However, the width of pods wasn't significantly different among the
cultivars in both two seasons.
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.
