Abstract
Wheat plants are attacked by the cereal aphids R.padi and S.graminum which are capable for causing severe injury owing to merely sap drainage. Therefore, 39 durum wheat varieties were sown in plastic pots in laboratory to seek out the influence of aphids infestation on wheat traits(1 st, 2 nd leaf blade length and seedlings dry weight). The results obtained can be summarized as follows: -The highest aphid number took place with, 33. Sc-10W1 variety followed by 14.Sc-1-DWI and SYTDW 41, varieties, while the least aphid population occurred on 6.SC OWL, S.Y.T.O.W 29,26 Sc.DWL and S.Y.T.D.W 27 varieties. -The highest percentage reduction of 1st leaf blade length took place with,S.Y.T.D.W. 5 variety, followed by S.Y.T.O.W. 8 variety and S.Y.T.D.W. 47 variety, while the least percentage reduction with 6 Sc. OWL 3 Sc.OW L,S.Y.T.O.W 24 and ,65c. 1.0WI varieties, respectively. -The highest percentage reduction of 2nd leaf blade length took place with,S.Y.T.D.W. 5, and S.Y.T.D.W. 44 varieties, respectively, while the least reduction occurred with 39. Sc. DWL, S.Y.T.D.W. 41,33. Sc.-1- DWI and 15.Sc. DWL varieties, respectively. -The results also indicated that the highest percentage reduction of dry weight seedling were recorded, with S.Y.T.D.W. 7, S.Y.T.D.W. 51 and S.Y.T.D.W. 5 varieties, respectively, while the least percentage re‌duction occurred with S.Y.T.D.W. 24,2 Sc. DWL and 34.Sc.DWL varie‌ties, respectively.
