نفِّذت عملية تهجين نصف تبادلية بين ست سلالات من الذرة الصفراء مرباة ذاتيّاً في قسم بحوث الذرة التابع للهيئة العامّة للبحوث العلميّة الزراعيّة في سورية خلال الموسمين الزراعيين 2010 و 2011 بهدف تقدير القدرة العامة و الخاصة على التوافق و كذلك قوّة الهجين لصفات الغلة الحبية (طن/هكتار)، ارتفاع العرنوس (سم)، و طول و قطر العرنوس (سم) و صفة الإزهار المؤنث (يوم) بالمقارنة مع الهجين باســل-1 و الهجيـن سبيـــــرو S-4-985 لتحديد أفضل الهجن من حيث الكفاءة الانتاجية في تجربة صممت وفق القطاعات الكاملة العشوائية، بثلاثة مكررات.
Half diallel set of crosses between six inbred lines of maize were executed at Maize
Research Department, General Commission for Scientific Agricultural Research
(GCSAR), Syria, during 2010 and 2011 seasons to study heterosis, general and
specific combining ability components for grain yield (ton/ha), ear height, length and
diameter (cm), and silking date (day) compared with control varieties Basel-1 and
the hybrid Spirou S-4- 985 to identify the best hybrid in terms of yield. Randomized
Completely Block Design (RCBD) was used with three replicates.
