Program 1: Minimising the impact of major barley foliar pathogens on yield and profit: Development of international host differential sets.

The development and maintenance of international host differential sets is a key resource for identifying new virulent pathotypes in the field and identifying novel sources of genetic resistance. This program aims to work and collaborate internationally to develop host differential sets for the net form of net blotch (NFNB, caused by Pyrenophora teres f. teres), the spot form of net blotch (SFNB, caused by P. teres f. maculata) and Scald (caused by Rhynchosporium secalis).

The knowledge gained from this coordinated effort will reduce duplication and redundancy in these key barley foliar disease host-pathosystems and facilitate the optimal deployment of new genes by breeding programs.
