A comprehensive study on maize germplasm resistance: To screened out promising germplasm/varieties of maize against Chilo partellus

Abstract

The germplasm/varieties of maize raised during Rabi season of 2020-2021 at oil seed farm, Kalyanpur and insectary department of entomology, C. S. Azad University of Agriculture And Technology Kanpur (U. P.). The soil of experimental field was study loam with homogenous average fertility level. The topography of the site of experiment was fairly prevented from the water logging condition. Geographical location of Kanpur district falls at 26.29° North longitude and 80.18 °C East longitude at an altitude of 125.9 m from the sea level. Observation on pink stem borer was recorded at 15 days intervals on five randomly selected plants, started from sowing to harvesting of the crop. In study we found that Azad Kanti, Azad PC-3, Azad BC-14, REHBC 1413-2, and Azad BC-5 were found resistant and HPC-5 more susceptible against stem borer, Chilo partellus.
