Screening of Maize Genotypes under Different Maturity Group against Maydis Leaf Blight Disease of Maize Caused by Helminthosporium maydis

The present investigation on was undertaken for the management of Maydis leaf blight disease of maize. In the Screening trial, 84 maize genotypes of the maturity group (NIVT-Late) were tested against Maydis leaf blight under artificial inoculated condition, according to Disease Severity scale (1-9), No any entry was found resistant, 7 entries were found as moderately resistant to Maydis leaf blight, 34 entries rated as moderately susceptible and 44 entries found susceptible to Maydis leaf blight. Hundred maize genotypes of the maturity group (NIVT-Medium) were tested against Maydis leaf blight under field condition, No any entry was found resistant, 20 entries were found as moderately resistant to Maydis leaf blight, 31 entries rated as moderately susceptible and 50 entries found susceptible to Maydis leaf blight. Out of 40 maize genotypes of the maturity group (NIVT- Early + Extra Early) one entry was found resistant, 10 entries were moderately resistant to Maydis leaf blight, 22 entries rated as moderately susceptible and 8 entries found susceptible to Maydis leaf blight. Susceptible check CML-186 rated as a susceptible reaction to Maydis leaf blight.
