الملخص EN

The study was carried out in Agricultural Research station of College of Agriculture/ Tikrit University at 17/11/2016, the population of second filial were planted for half diallel crosses by 45 crosses with its ten parents: (PO6-OO1FB/FL, PO6-OO2FB/FL, PO6-OO3FB/FL, PO6-OO5FB/FL, PO6-OO9FB/FL, PO6-OO11FB/FL, PO6-OO13FB/FL, PO6-OO14FB/FL, Syrian Local large and Aguadolce) of Faba Bean crop (Vicia faba L.

) by using Randomise Complete Block Design (R.

C.

B.

D) by three replicates, the evaluation of the genotypes was showed surpassing of the parent (2) for five traits: (number of the days for 50% flowering, plant height, leaf area, number of the seeds in the pod and single plant yield) the parent (5) was surpassed in two traits: (number of the branches, and biological yield) the parent (8) in two traits: (seed yield and harvest index), the parent (9) was surpassed in yield efficiency and the parent (7) in the number of the pod and the parent (3) in seed weight trait the crosses (1×5), (1×6), (1×10), (2×9), (3×5), (5×9), (6×7), (7×9), (3×10) and (8×10) in the traits: (number of the days for 50% flowering, plant height, leaf area, number of the branches, number of the pods, number of the seeds in the pod, weight of the seed, single plant yield, seed yield, biological yield, harvest index and yield efficiency).

The combining ability effect results the parent (2) had significant effect for general combining ability to desired direction, and the excessing for all the traits except the traits: (number of the pods, weight of seeds, seed yield, biological yield, harvest index and yield efficiency) also the parent (8) gave significant effect for general combining ability to desired direction for the traits: (number of the days for 50% flowering, weight of seed, yield of the seeds, biological yield and harvest index) the parent (9) for the traits: (number of the branches, number of the seeds in the pod, weight of the seed, single plant yield and yield efficiency) therefor it may useful to use these parents and entered them in the crosses program in the future The more crosses which surpassed in the effects of specific combining ability were: (2×7) and (4×6) for nine traits, (5×9) for eight traits, (5×6), (8×9) and (8×10) for seven traits, (1×10), (1×3) and (5×10) for six traits, (1×2), (1×8), (2×9), (3×6), (3×7), (3×8), (4×7) and (9×10) for five traits, (1×4), (1×5), (1×7), (3×4).

(3×10), (4×10), (5×8), (6×7) and (6×8) for four traits and nine crosses for three traits.

The best parents which transport its performance in the traits for its generations regularly were: the parent (1) for the days to 50% flowering, the parent (2) for plant height, leaf area, biological yield and single plant yield, the parent (3) and (5) for number of the pods, the parent (6) for harvest index, the parent (9) for number of the branches, number of the seeds and yield efficiency, the parent(8) for seed weight and seed yield, so it can use these parents and its crosses for the aim of transporting the genes and selection for desired traits.
