اختُبرت عشيرة من القمح الطري، تعيش طبيعياً على حواف سبخة عين مليلة المالحة، الواقعة إلى جنوب شرق قسنطينة من الشرق الجزائري، مع أربعة أصناف من القمح الطري (HD1220, ARZ, AS, ANF)، بهدف تقييم أدائها تحت ظروف عدّة إجهادات لاأحيائية، بالإضافة إلى دراسة مدى استجابتها للتسميد المضاف، و ذلك اعتماداً على جملة من الصفات التطوريّة، و الشكليّة، و الكيميائيّة للنبات مثل: دورة الحياة (من الزراعة و حتى ظهور 4/1 السنبلة)، و القدرة الإنباتية، و القدرة على الإشطاء، و المساحة الورقية، و المحتوى من الكلوروفيل الكلي، و المحتوى المائي النسبي، و المحتوى من السكريات الذوابة.
A population of soft wheat which lives naturally on the edges of saline Ain Malilah’s Sebkha, located to the southeast of Qasantina from the east of Algeria, and four varieties i.e. HD1220, ARZ, AS and ANF, to evaluate their performance under several abiotic stresses conditions, and to study their response to fertilization, based on some phenological, morphological, chemical characteristics such as: Life cycle (from cultivation until the appearance of 1/4 spikes), germination potentiality, tellering, leaf area, total chlorophyll content, relative water content, carbohydrates content.

Eleven genotypes of Bread Wheat (Triticum aestivum L.) were tested at three diverse
locations in the Syrian Coast during the 2015-2016 season under rain-fed conditions to
assess these genotypes and to study the Genotypes x Environments Interactions
, and yield
stability across environments using 5 statistical measures of stability:{ X¯i, bi, and i
according to Eberhart and Russell (1966), Stability Variance Index (2
i) according to
Wricke and Weber (1980), Ecovalance Stability Index (Wi) according to Wricke (1962)}.
Genetic material included 5 promising lines and 6 local varieties (provided by ACSAD and
GCSAR).The experiment was designed using randomized complete block design with
three replications, statistical data analysis was done, and least significant difference
(L.S.D) test at 5% was applied for comparison of means. Significant differences were
observed among bread wheat genotypes for grain yield (ton/ha), combined analysis of
variance of grain yield across the three environments showed significant mean squares due
to genotypes, environments and genotypes x environments interaction, suggesting
differential responses of genotypes across studied environments and validity of stability
analysis.
Stability analysis for grain yield revealed that; the promising line ACSAD-1147 and
Doma6 were more stable than other genotypes. Due to they had superior ranks for both
average yield over environments and yield stability, which reveals the importance of these
genotypes to reach varieties that combine relatively high yield and better stability in any
future breeding programs.
This study was carried out in 2009-2011, in the laboratories of science faculty -
Tishreen University. The seeds of three genotypes: Sham8, Sakha8,AUS 29639 of bread
wheat were planted in hydroponic cultures irrigated with Hoagland liquid in a grow
th
chamber to compare the effect of three salt concentrations (0, 100,200 mm of NaCl) on
proline and carbohydrate contents in three growth stages 21, 28, 35 of the experiment.
There was an increase of proline and carbohydrate contents in all cultivars with
increased salinity during the three growth stages of plants. Proline contents increased in
Sham8 with low rates compare with Sakha8, AUS 29639. It increased in Sakha8 with the
increase of salinity which reached 348% in the third growth stage in concentration 200 mm
NaCl, while Proline concentration reached the highest value in AUS 29639 (524%). The
carbohydrate content reached the highest value in Sakha8 in NaCl concentration 200 in the
first growth stage (238070%) compared with the control, and (204.34%) in third stage in
NaCl concentration 200mM compare with the control.
The results of the study indicate the superiority of Sakha8, AUS 29639 in salt
tolerance through accumulating suitable rates of proline and carbohydrates. AUS 29639
was more resistant to salt stress than Sakha8. We may use these results later in other
physiological and genetical studies.
This research was conducted at the farm of Abu-Jarash, Faculty of
Agriculture, Damascus University. The aim of this research was to
evaluate the performance and productivity of 9 bread wheat (T.
.aestivum )and 3 durum wheat T. durum.
The experiment was laid out in a Random Complete Block design
(RCPD) with three replication.
The present investigation was conducted during 2010/2011 and 2011/2012
growing seasons at Karahta station for field crops research, General
Commission for Scientific Agricultural Researches (G.C.S.A.R.), Syria. Forty
five hybrids F1 produced using
a half diallel cross among ten bread wheat
(Triticum aestivum L.) genotypes, in 2010/2011 season, were evaluated during
2011/2012 season in order to study som of the genetic parameters for grain
yield per plant, its components, some morphophysiological and quality traits to
determine the basic criteria for selection.
This research was conducted to determine the most responsive phenological
stage for supplementary irrigation of the durum wheat in a primary stationary
region.
It consisted of six different water treatments in addition to control (non
irrigated)
:
1-From planting to seedling emergence; 2-From planting to tillering; 3-From
planting to booting; 4-From planting to flowering; 5-From planting to the end of
the milk stage; 6–Sowing irrigation and irrigation according to necessity
throughout the milk stage.
The study has been repeated in four blocks for three seasons from 2002 to
2005. The results of the first two seasons showed that the:
The treatment from planting to booting, was canceled because of the rain and
soil dampness during this growth period. A significant increase in production,
water use efficiency, and one 1000 kernel weight, of both 5th and 6th treatments was
noticed in comparison with other treatments and the control. Results of the three
seasons were varied due to the environmental variation in temperature and amount
of rainfall.
