اجريت الدراسة خلال الموسم الصيفي 2011 في موقعين ( جامعة تكريت و مدينة الرمادي ) وتضمت عاملين الاول اربعة تراكيب وراثية والثاني اربعة مواعيد جني بهدف دراسة تأثير موعد الجني في الصفات النوعية لتلك التراكيب ، واظهرت النتائج ان لمواعيد الجني تأثير معنوي في الصفات النوعية لكلا الموقعين وان كل من التراكيب الوراثية والموقع وموعد الجني كان له تأثير في الصفات المدروسة فضلا عن التداخل بين عوامل الدراسة .
