Abstract
A field experiments were carried out in 2011 and 2012 on cucumber in the plastic houses of General Company of Horticulture and Forestry, to study general and specific combining ability, gene action and another genetic parameters. Six inbred lines were crossed in full diallel crosses to produce hybrids, crosses, parents and F1 hybrid (Seif) were tested in yield and other traits evaluation. The results obtained revealed that the best hybrid in the yield per plant, fruit number/plant, number of flowers/ plant and fruit Weight set percent was 6×5 and 6×1 gene action for plant yield, fruit number and number flowers/plant was non additive action. Fruit weight and fruit length was additive action, while (h2.bs) was high in all characteristics, and (h2.n.s) was high in fruit weight and fruit length. The best (gca) and (sca) in parents 1, 5, 6 that there crosses 6×5 and 6×1 gave high yield per plant 2.949, 3.353 and 2.866, 3.236 kg/plant than hybrids that surpassed an compare hybrid Seif 2.561, 2.623kg/plant
