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.
Seven cotton varieties ( Rakka5, Aleppo133, Aleppo90, Aleppo118 , Aleppo40,
Deir22, Line124) were grown in village Salhab ( Al-Ghab region , Hama) in 2012 using
randomized complete block design with three replications. were used to study estimation
of variance, broad sense heritability, genetic progress and correlation some of their
technological characters (Staple length mm, Length uniformity% , Fiber fineness
%(micronaire), trength Fiber(g/tex), Fiber elongation%, fiber maturity%), that’s to explore
potentials Genotypes in search region and put the numerous selectoral evidence in order to
obtain an additive and fast improve on the technological characters,
The study showed significant differences between in the studied genotypes, for
most of the considered traits.
The study suggested a variation of the values of Heritability, Genetic advance in the
characteristics technological of cotton., the highest Heritability of which was in the Staple
length and than trength Fiber, Fiber elongation , Fiber fineness, fiber maturity, Length
uniformity, characteristics where the inheritance degree reached (0.98, 0.97, 0.89,
0.80,0.75, 0.30) , genetic development% (1.03, 1.35, 0.36, 1.31,1.22, 0.11).
The results also showed a positive significant correlation between Staple length and
trength Fiber (r = 0.901**), also between Fiber elongation with fiber maturity and Length
uniformity ( r = 0.64**, r = 0.422**), and this gives us the area and ease of movement to
put the numerous selectoral evidence in order to improve the technological characters of
cotton.
Seven cotton varieties (Rakka 5, Aleppo133, Aleppo 90, Aleppo 118, Aleppo 40,
Deir 22, and Line124) were used in the study of some quantitative characteristics of cotton
yield and its components (seed cotton weight per boll/g, 100seed/g weight aver
age, lint
percentage %, seed cotton weight per plant/g, total dry matter weight, seed cotton yield per
unit area kg/ha), and physiological qualities (leaf area cm2, leaf area index %). The seven
varieties were grown in Salhab (Al-Ghab region, Hama) in 2012 using randomized
complete block design with three replications.
The study included estimating variance, broad sense heritability, genetic progress,
and genetic correlation between cotton yield and its components, which is to be used in
breeding programs.
Seven cotton genotypes (Rkka5, Aleppo1-33, Aleppo90 – Aleppo 118,
Aleppo 40, Deir22, and Line124), were used to estimate variance and genetic
and phenotypic correlations between seed cotton productivity and its
components [earliness in flowering a
nd maturity(day), plant height (cm),
number of vegetative and reproductive branches, number of bolls per plant,
100 seed weight (g), average boll weight (g), lint percentage (%), and plant yield
(g)], to be used as selection indices for higher yield performance in breeding
programs. The experiment was carried out in Al-Ghab region (Hama) in 2012-
2013 growing season using randomized complete block design (RCBD) with
three replications.
A half diallel set of crosses among six highly diverse barley (Hordeum
vulgare L.) genotypes were evaluated at Karahta Research Station, General
Commission of Scientific Agricultural Research (GCSAR), during 2010-2011
and 2011-2012 seasons to stud
y heterosis, potence ratio, correlations among
traits and path coefficient analysis for number of spikes per plant, number of
grains per plant, number of grains per spike, biological yield ,and grain yield
per plant. Heterosis effects for seed yield ranged from%-89.52 (T-6669×S-6303)
to%16.99 (Arabi abiad mohsan×S-6689) and from%-49.94 (L-6711×S-6689)
to %-1. 35 (Arabi abiad mohsan×S-6689) relative to mid and better parents
respectively. Potence ratio values ranged from 1.14 (number of spikes per
plant) to 3.50 (biological weight) indicating that non-additive gene action was
more important in controlling all studied traits. Correlation coefficients among
traits indicated that seed yield was positively and significantly associated with
each of number of spikes per plant (0.289), number of grains per plant (0.832),
number of grains per spike (0.587), and biological yield (0.708) traits. Path
coefficient analysis indicated that number of grains per plant trait had high
positive direct effects on grain yield.
The experiment was carried out at two planting dates in a Randomized
Complete Blocks Design with three replications at Maize Research Department,
General Commission for Scientific Agriculture Researches (G.C.S.A.R.)
Damascus, Syria, during two cro
pping season 2011 and 2012 to study the
phenotypic and genotypic coefficients of variation, heritability, genetic advance,
phenotypic correlation and path coefficient analysis for grain yield per plant,
its components and the height of plant and ear of two maize hybrids (IL.292-06
× IL.565-06, IL.459-06 × IL.362-06).
The experiment was conducted at Tayba Research Station, General
Commission for Scientific Agricultural Research during 2011-2012, and 2012-
2013 growing seasons. Randomized block design with three replications was
used to investigate phenotypic va
riances and to determine correlation of yield
components of six local genotypes of radish. Significant differences between
genotypes were appeared in diameter, length and weight of radish root. The
correlation analysis revealed that root weight was positively and significantly
correlated with both yield (0.964) and root diameter (0.274). Yield was
positively and significantly correlated with root diameter (0.382). Root length
was positively and significantly correlated with plant height (0.333) and
number of leaves (0.329) per plant.
This research includes evaluating the work of maintenance of themachines through
their own key performance indicators (KPI), and approved byindustrial and service
companies, We mention reliability, readiness ,average time between failures, average
Repair time ,average time of periodic maintenance of their production and
serviceequipment.
After the data processing of emergency failures and periodic maintenanceof
machines , we extracted values for maintenance performanceindicators, we measured
their performance and correlation to evaluateits compatibility with global indicators.
The research aim to assess the current situation through the use ofquantitative
methods pattern which is used to access the values of theprevious mentioned performance
indicators and their interdependence tobe used in support of maintenance decisionsin the
container terminal later.
We noticed a strong inverse association between periodic maintenance TPMtime and
breakdown TBD, and reached a value rERS = -0.99, and thereforewe must focus on
increasing periodic maintenance to reduce breakdowntime, and replace parts that cause
recurringproblems which caused about intensive breakdowns, thus reducing
periodicmaintenance time.
Also we were able to classify the quality of maintenance and machinesthrough the
readiness and reliability indicators and the mean timebetween failures.
This research aims to investigate the impact of fluctuations in the
exchange rate of the Syrian pound on the general index of the prices
of shares of companies listed in the Damascus Securities Exchange,
and clarify the type of relationship betwee
n these fluctuations and
general share price index,using the linear regression models simple
and multiple, and vector autoregressive (VAR) model of error
correction (VECM) and Granger causality to test the relationship
between the exchange rate and the general share price index in the
Damascus Securities Exchange for the period 2011-2015.
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.
