Abstract
A new method for assessing resistance to Pythium snow rot of barley was developed. The level of resistance was quantitatively expressed as lesion length extended to the basal direction from the inoculation point at the middle of the leaf blade. The varietal difference of barley in the resistance determined by this method was consistent with that determined by the snow mold chamber method. Using this method, we could evaluate the resistance within 10 days after inoculation. Furthermore this method was useful to estimate the resistance to snow rot of wheat, rye, and oat.
