P mildew of barley is caused by Erysiphe graminis DC. f. sp. hordei Em. Marchal. Most of the commercial barley varieties currently planted in West Virginia and adjacent states are not highly resistant to this disease and may be severely damaged when weather favors the development of the pathogen. This disease can be controlled by spraying or dusting with certain fungicides; but these methods of control are not economical except on an experimental basis. Therefore, the use of resistant varieties provides the only practical means of control. A considerable number of barley varieties and selections have been found by Briggs and associates (1, 2, 12, 14), Dietz (3), Mains and Martini (4), Poehlman (11), Tidd (15), and Moseman and associates 5, 7, 8, 9, 10) that are resistant to certain races of the fungus found in North America. A number of different genes found by these investigators condition such resistance and their relationships have been determined. The present study was undertaken for the purpose of determining (a) the mode of inheritance of resistance to several specific races of the fungus in winter barley varieties, and (b) the genetic relationship between different sources of resistance.
