Sources of Resistance to Powdery Mildew (Erysiphe polygoni DC.) in Peas

Hamidullah Jan

Thirty four pea germplasm lines, obtained from Washington State University, Pullman, USA, were evaluated with two commercial cultivars against powdery mildew under field conditions at Battakundi (Kaghan valley) during summer, 1995 and 1996. The disease appeared in severe form killing the check cultivars ' Meteor and Mingomark' completely in all the past plots. Ten entries were found highly resistant, ten moderately resistant and four tolerant, whereas ten exhibited moderately susceptible or highly susceptible reaction. The two commercial cultivars Meteor and Mingomark were found highly susceptible to the disease.
