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.

Research summary
تتناول هذه الدراسة البحث في درجة التوريث والتقدم الوراثي ومعامل الارتباط لبعض الصفات التكنولوجية في سبعة طرز وراثية من القطن (حلب133، حلب90، رقة5، دير الزور22، حلب118، حلب40، السلالة124). أجريت التجارب في قرية سلحب بمنطقة الغاب في محافظة حماه خلال الموسم الزراعي لعام 2012 باستخدام تصميم القطاعات العشوائية الكاملة بثلاث مكررات. هدفت الدراسة إلى تقدير التباين الوراثي، درجة التوريث العامة، التقدم الوراثي ومعامل الارتباط لبعض الصفات التكنولوجية مثل طول التيلة، انتظامية طول التيلة، النعومة، المتانة، الاستطالة، ودرجة النضج. أظهرت النتائج فروقات معنوية بين الطرز المدروسة لمعظم الصفات، حيث كانت أعلى درجات التوريث لصفة طول التيلة (0.98) وأدناها لانتظامية طول التيلة (0.30). كما أظهرت النتائج ارتباطاً إيجابياً قوياً بين طول التيلة ومتانة التيلة (0.901) وارتباطاً إيجابياً بين استطالة التيلة ودرجة النضج (0.422) وانتظامية الطول (0.64). توصلت الدراسة إلى أن هذه الصفات يمكن استخدامها كأدلة انتخابية لتحسين الصفات التكنولوجية للقطن.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين الصفات التكنولوجية للقطن، حيث تقدم معلومات قيمة حول درجة التوريث والتقدم الوراثي ومعامل الارتباط بين الصفات المختلفة. ومع ذلك، يمكن أن تكون الدراسة أكثر شمولية إذا تم تضمين المزيد من الطرز الوراثية وتوسيع نطاق الدراسة لتشمل مناطق زراعية أخرى. كما أن استخدام تقنيات تحليلية أكثر حداثة يمكن أن يعزز من دقة النتائج. بالإضافة إلى ذلك، قد يكون من المفيد تقديم توصيات أكثر تفصيلاً حول كيفية تطبيق النتائج في برامج التربية العملية.

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.
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.
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).
This research has been carried out at the experimental Station of Agriculture Faculty, Damascus University during the period of 1998-2000. Five parents were selected from the Cotton Office Germplasm (Aleppo40, Raqua5, Dir22, Daltabain50, 88G6104) to examine the inheritance of some morphophysiological, yield, and quality related traits. In1998, the five parents were hand-crossed in all combinations (with no reciprocals) generating ten F1 hybrids. During 1999, the ten crosses and their parents were planted to produce F2 seeds. In 2000 the F1s, F2s, and their parents were grown in a randomized complete block design with two replications. Heritability estimates in broad sense showed that the earliness traits possess the highest values, followed by total and actual bolls number, indicating the importance of additive gene action in the inheritance of these traits. Whereas, heritability values for other traits were markedly different, revealing the genetic diversity of these hybrids parents. High estimates of expected genetic advance were found to be associated with high heritability estimates for total and actual bolls number, indicating that direct selection should be effective for these traits. On the other hand, improvement of traits, possessing intermediate estimates of genetic advance and high heritability estimates, such as total bolls number, harvest index, flowering earliness and fiber elongation in some studied hybrids, through direct selection might be less effective. The results suggest that traits with high heritability estimates associated with low estimates of genetic advance; and those possess intermediate estimates of heritability and genetic advance or low estimates of both parameters are most likely controlled by non-additive genes, therefor, direct selection might not be effective for improving these traits.
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.
