Abstract:                                                                                              

           Barley induced mutant (D/31) was significantly approved having a slow mildewing resistance under field conditions and epidemic form of powdery mildew. The host reaction of this kind of resistance was demonstrated throughout the crop season based on the number of mildew pustules per tiller at 8 different times with 10 days intervals. The number of pustules found on D/31 represented only 5-145 of those counted on Numar.The slow mildewing resistance in D/31 is successfully approved throughout the infection rates during whole growth season. The slow mildewing of D/31 found to be of polygenic in nature.
