Screening of Mustard Germplasm against Powdery Mildew (Erysiphe cruciferarum) and Analysis of Yield Contributing Characters

The current experiment was carried out at the Regional Agricultural Research Station (RARS) Polasa, Jagtial during rabi 2020-21, with goals of (1) assessing resistance Indian mustard germplasm lines to powdery mildew disease and (2) analysing yield its contributing traits, days 50% flowering, maturity, plant height in centimetres, primary branch number, secondary siliqua number length centimetres. results analysis variance showed that there were statistically significant differences between genotypes their characteristics. viz., DRMR-150-35, Black gold, RH-9304 performed best on average 50 different varieties for twelve characteristics, including high seed per plant, 1000-seed weight harvest index.Two resistant (GM-3 Swarna Jyothi) nine (Pusa mahak, PM-25, PM-26, PDZM-31, Pusa tarak, bahar, Ashirwad, DRMR-601, JM-2) demonstrated considerable reaction after being screened against illness. We can solve effect problem by utilizing these as donors future breeding programme develop lines.
