The international program wheat varieties (IWWPMP) resistance to the powdery mildew causing agent

Abstract

IWWPMP (International Winter Wheat Powdery Mildew Program) is being conducted over a long period of time and our team is involved in it for over two decades. In the last couple of years, the Coordinator of this program has been Dr. Stevan Leath from the North Carolina State University, U.S.A The attached paper discloses the 1990-1992 results obtained in the localities of Kragujevac and Novi Sad. Our investigations revealed that not all the varieties included in this program are resistant to Powdery Mildew. In the three years of our investigations (1990-1992) at the two localities (Kragujevac and Novi Sad), the number of resistant and the number of susceptible varieties has been approximately the same.
