تضمن البحث دراسة تأثير خواص الصنف الوراثية في حجم الدرنات و تركيبها الكيميائي لخمسة أصناف بطاطا مدخلة حديثاً الى القطر( أطلس Atlas ، بورين Bureen ، بومبا Bomba ، رومبا Rumba، و الصنف أورلا Orla) إضافة إلى الشاهد سبونتا Spunta، نفذ البحث في مشتل جامعة تشرين في عروة ربيعية للموسم الزراعي 2012 . أظهرت النتائج أن الأصناف أطلس، و بورين، و بومبا أعطت أكبر نسبة من الدرنات الكبيرة الحجم، في حين سجل الصنف بومبا أعلى إنتاجية للدرنات التسويقية (7.8 كغ/م2). كما أظهرت النتائج أن أعلى نسبة للمادة الجافة ( 20.5%) و الرماد (1.01%) سجلت في الصنف رومبا، بينما أعلى نسبة للنشا سجلت في الصنفين سبونتا و بورين ( 14.5 و 14.4 % ) على التوالي، و سجلت الأصناف رومبا و سبونتا و بورين أعلى نسبة لفيتامين C ( 19.36 ، 17.6، 17.6 مغ / 100 غ ) على التوالي، و تميز الصنف رومبا بأكبر نسبة للبروتين (1%) و المواد الصلبة الذائبة الكلية (5%).
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 varieties 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.

The aim of this study was comparing between three potato cultivars: "Afamia,
Loulou and Tadmur" which are planted in two different times (spring time and autumn
time), for the plant old age and some yield properties and some quality properties. Aft
er
ripping and harvesting, result showed superior Loulou to Afamia and Tadmur in most
parameters at the two planting times, so the productivity of Loulou was more than Afamia
by 6 ton/h in the spring and 1.6 ton/h in the autumn. For the starch and dry matter content,
Loulou tubers in the two planting times contained more amount than the other cultivars,
and more than the global average (%14 starch, %22 dry matter).
The research aimed at estimating the optimum size of
autumn potato farms in Al-Qusir district-Homs province. A simple
randomized sample of 192 farmers has been taken from five
different villages. The sampled farms were divided into four
classes b
ased on size.
The results showed that the production, return, net return
and the net profit of 1 SYP/ Donnum were increased along with
size of the farm .By using one way Anova, The analysis showed
that there were statistically significant differences among the size
of farms based on the above-mentioned measures.
This study was conducted at Abo Jarash farm, Faculty of Agriculture,
Damascus University In order to determine the response of three local varieties
of potato (Sponta, Draja, Diamont) to salinity stress with different
concentration of NaCl solutio
n (0,50, 100, 150, 200 mM). The results indicated
that the existence of a inverse correlation between increased concentrations of
salts in the solution and the rate of plant height, leaf area, and the percentage of
leaf dry weight, and the proportion K+/ Na+., and the productivity was declined
with a proportional rate 22< 32, and 48% for the varieties of Sponta, Draja,
Diamont, respectively. Results indicated the existence of reverse relationship
between increasing salt concentration in the medium and plant height, Leaf
area, dry weight of the leaves and K+/Na+ ration in addition to the decline in the
productivity of studied varieties. The results also showed variations in the
extent of tolerance between studied varieties to salinity stress where Sponta
was the most tolerant, followed by Draja and Diamont was the less tolerant and
this was reflected in terms of higher germination and increasing the mean of
plant height, Leaf area and dry weight of plant.
The pathogenicity of three isolates of the fungus Beauveria
bassiana (Bals.) Vuill were evaluated on potato tuber moth
Phthorimaea operculella (Zeller) (Lep.,Gelechiidae).
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 germ
ination 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.
