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.
This study aimed to definition the daily changes of table grape prices which
sells to the exporters in the wholesale market, analysis these prices, definition
it's contrasts, explanation the contrasts causations. That’s prices which table
grape ta
ke it in AL-Hal's market in Damascus that it's the single wholesale
market in Syria for sale the table grape as wholesale. And we build this study
as analysis study for the daily prices time series during seasons (2006, 2007,
2008) depend on the daily prices average (in each seasons), and we depend on
the difference between the seasons data for the comparative study. Then the
study abide to explanation the changes of table grape prices in each marketing
ways, and the way importance depending on the price.
This research aims to analyze the wholesale prices for both types of table grape
Helwani and Baladi in AL-Hal`s Market in Damascus city, being the main center
for selling grapes of south area in Syria. It has been done as a sector research for
one
season 2003, as will as the applied selling techniques in this market were
determined.
The maximum and minimum prices for both categories were recorded
depending on some commission traders, producers, guarantors and exporters, daily
and round the season, which the beginning and end for each were determined.
Centralization and deviation measurements; in addition to correlation coefficient
for prices averages for both the two prices and the two weekly prices range were
calculated. The correlation with each other, the correlation of each with time, and
the regression functions for previous relations were defined.
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.
