Adult-plant resistance to leaf scald and net form net blotch in food barley genotypes at a hot spot location in Ethiopia.

ABSTRACT: Globally, the fungal pathogens Rhynchosporium graminicola and Pyrenophora teres f. teres produce foliar diseases that significantly reduce barley yield. These diseases are known as leaf scald and net form net blotch, respectively. One hundred food barley genotypes in reaction to the diseases were assessed in Ethiopia's natural environment. Since Ethiopia is a secondary center of genetic diversity in barley and consequently its pathogens, this assessment is certainly of interest in identifying new sources of resistance and using the identified genotypes in breeding. In addition, effect of the diseases on yield and yield components of food barley and the association between the parameters were studied. A simple lattice design was used for the field testing.
