| Abstract | ||
| The results revealed that Smito cultivar of wheat recorded highest reduction percentage in growth and yield criteria as a result of nematode infection comparing to Sham4,Caroniya and Icsad cultivars in which the reduction percentage in plant and spike lengthes and hay weight reached it’s minimum value, in addition the minimum reduction percentage in biological yield,number and weight of grains were recorded in Tamoz2 cv. On the other hand the percentage infection was restricted between Tammoz2 and Sham 6 as minimum (22.3%) and maximum(62.5)Percentage respectively.Regarding to barley cvs. the reduction percentage reached it’s maximum in plants lengths,hay weight and biological yield in Acsad 14 cv.and in spike lengthes in Local white cv.and in number and weight of grains in Kahtan cv.while reduction percentage reduced to it’s minimum levels in plant and spike lengthes,hay and biological yield weight, number and weight of grains in the Local black, Rayhan,Kahtan,Reseaches1,Zanbaka and Tadmur cvs.respectively.results also indicated that all barley cultivars were severly susceptible to nematode in which infection percentage did not decline from 79%in Local white cv.and rechead it’s maximum percentage (100%) in each of Acasd14,Rayhan,Forat,Local black and Kahtan cvs. | ||
