Abstract

Powdery mildew caused by Erysiphe pisi is a major disease severely affect pea production in areas with warm and dry days, and cool nights. It is essential to identify/develop resistant genotypes for commercial use or to incorporate resistance in cultivars using different breeding approached supplemented with marker-assisted selection. Considering the high potential of pea production in India, a study was conducted to screen ten newly developed genotypes along with four recommended check varieties viz., Him Palam Matar-1, Azad P-1, Lincoln and Pb-89 under field and in-vitro conditions during the years 2020-21 to 2023-24. Three lines namely, DPPMR-09-1, DPP-MR-09-6 and DPP-SN-2 showed resistant reaction against powdery mildew while DPP-SP-6, DPP-SN-5 and DPP-SN-10 were identified with moderately resistant reaction. The identified resistant genotypes may be directly utilized or incorporated into high-yield, disease-susceptible genotypes through hybridization.
