For the factorial hybridization procedure, ten pure maize lines were used as parents: DR-F-53, MA-F-53, H-4, DKC-F-59, IK-58, and ZP-595 for the males, and POL-F-6, SYM-F- 53, MY-F-53, and SYN-F-54 for the females. Using a randomized full block design with three replications, seeds of both pure lines and hybrids were planted in the fields of the College of Agriculture and Forestry throughout the fall season of 2022. The purpose of this study was to investigate the impacts of general and particular combining ability, genetic factors, and heterosis. All attributes examined had a statistically significant mean square of male and female parents and their interaction at the 1% probability level. Number of days to tasseling and silking qualities had general to specific combining ability components larger than one, and all traits tested had additive and dominant genetic variances values that were significantly different from zero. The average degree of dominance was larger than one for all characteristics, and the broad sense heredity % was high across the board. On the other hand, the number of days tasseling and silking attributes had narrow sense heritability that was high. The specific combining effect results demonstrated that the hybrid MY-F-53 × H-4 had a significant desired effect for all traits, while the general combining ability effects demonstrated that the parental lines H-4, IK-58, and ZP-595, as well as the maternal line SYN-F-54, had desirable effects for all traits. The hybrid IK-58 x SYN-F-54 outperformed the other parents in terms of heterosis, which is defined as the departure of F1 from the better parent, in terms of number of days to tasseling and silking, number of grains per ear, and grain production per plant.

The experiment was conducted in the fields of the College of Agriculture and Forestry University of Mosul for the autumn season 2022-2023, and Ten genotypes were used, namely (DR-F-53, MA-F-53, H-4, DKC-F-59, IK-58, ZP-595, POL-F-6, SYM-F-53, MY-F-53 and SYN-F-54) To study the genetic stability of genotypes of maize according and the experiment was a The Randomized Complete Block Design (R.C.B.D) was used with three replicates and the traits of studied (date of tasseling , date of silking , number of ears per plant , number of grains per ear , weight of 500 grains, single plant production) . The results showed that in terms of genetic, phenotypic and environmental variations, heritability in the broad sense, and the expected genetic improvement as a percentage, it was high for all genotypes and for all traits, and this gives an opportunity for selection for these superior traits.

The experiment was conducted in the fields of the College of Agriculture and Forestry University of Mosul for the autumn season 2022-2023, and 10 genotypes were used, namely (DR-F-53, MA-F-53, H-4, DKC-F-59, IK-58, ZP-595, POL-F-6, SYM-F-53, MY-F-53 and SYN-F-54) and the experiment was a The Randomized Complete Block Design (R.C.B.D) was used with three replicates and the first factor was the genotypes, which are (10) and the second factor is three dates, which are (July 23, August 30 and August 6), and the traits of studied (date of tasseling , date of silking , number of ears per plant , number of grains per ear , weight of 500 grains, single plant production). The results of the variance analysis table showed that the genotypes, dates and interaction between them were significant and for all traits. For the first factor of genotypes superior the genotype (9) for the traits of date of tasseling and silking and the weight of 500 grains and superiority of the genotype (1) for the traits of the number of grains per ear and the single plant production and for agricultural dates exceed the first date for the traits date of tasseling and the number of ears and the weight of 500 grains and the single plant production and the interaction the genotypes and agricultural dates superior the genotype (9) for the traits of male flowering and single plant production

نفذت هذه التجربة خلال الموسم (2013-2014) في موقع جامعة الموصل كلية الزراعة والغابات حيث تم زراعة خمس مدخلات من الشعير العاري مصدرها المركز الدولي للبحوث الزراعية في المناطق الجافة (ICARDA) بالإضافة الى الصنف المحلي ريحان 3- وثلاث كثافات نباتية (200-300-400 بذرة /م2) تحت الظروف الديمية . نفذت التجربة باستخدام نظام الالواح المنشقة بتصميم القطاعات العشوائية الكاملة بثلاثة مكررات وتم دراسة الصفات : طول السنبلة (سم) وعدد الحبوب في السنبلة وعدد السنابل/م2 وحاصل الحبوب كغم/هـ ووزن 1000 حبة (غم) .اظهرت النتائج اختلاف اداء التراكيب الوراثية تحت الدراسة بإختلاف الكثافات ، تفوق التركيب الوراثي TOCTE/PETUNIA 2//PETUNIA 1على بقية التراكيب الوراثية في صفات طول السنبلة وعدد الحبوب في السنبلة وحاصل الحبوب وتفوقت صفات عدد السنابل/م2 وحاصل الحبوب ووزن 1000 حبة عند الكثافة 400 بذرة/م2, كانت قيم التوريث بالمعنى الواسع والتحسين الوراثي المتوقع من الجيل التالي عالية لصفات طول السنبلة وعدد الحبوب في السنبلة وعدد السنابل/م2 وبالنسبة لوزن 1000 حبة (غم) كان التحسين الوراثي المتوقع عاليا فقط عند الكثافة 200 بذرة/م2 ومتوسطا لكل من الكثافتين 300 و 400 بذرة/م2 . اظهرت نتائج تحليل معامل المسار ان وزن 1000 حبة كان لها التأثير الأكبر على حاصل الحبوب عند الكثافات الثلاث وراثياً ومظهرياً ، ويمكن استخدامها في برامج التربية لتحسين حاصل الحبوب.
