استُخدمت تسعة طرز وراثية من القطن السوري و هي: (حلب 33/1، حلب 118، حلب 90، حلب 40، حلب 124، رقة5، دير الزور 22، السلالة 106، سلالة الرصافة) لإجراء التحليل الاحصائي و الوراثي للإنتاجية، و بعض مؤشرات التركيب الكيميائي للبذور (معدّل الحليج %، إنتاجية النبات الواحد/غ، نسبة الزيت في البذور و لبّها%، نسبة البروتين في البذرة و لبّها%، نسبة الرطوبة في البذور و لبّها%)، و ذلك لمعرفة إمكانيّات الطرز الوراثيّة في منطقة البحث، و وضع برنامج لإنتاج القطن و البذور معاً، و معرفة الأدلة الانتخابيّة التي تستخدم في تحسين قيمة كلٍّ من إنتاجيّة القطن و مكوّنات البذور، و ذلك بتصميم القطاعات العشوائية الكاملة و بثلاث مكررات، في قرية سلحب بمنطقة الغاب، التابعة لمحافظة حماه في سورية، في الموسم الزراعي 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 percentage%, 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.

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 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.
Succes of a breeding program depends, to a great extent, on understanding
the gentic behavior of the traits. This investigation was conducted to study and
examine the inheritance of some economically important characters such as:
total bolls numbe
r, actual bolls number, ginning percentage , boll weight,
harvest index, flowering earliness, maturity earliness, plant height,and fiber
fineness.
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).
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.
