Evaluation of Rice Germplasms at different Cropping Stages for Resistance to Cnaphalocrocis medinalis

Twenty five rice germplasms were tested and six germplasms viz., IET 13310, NDR 6023, IET 10649-1, Mahsuri, NDR 6232 and NDR 6175 showed a consistent damage rating of 1. Among the plant morphological characters studied, number of tillers, plant height (cm), number of leaf, leaf width (cm) and leaf texture, only leaf width (cm) showed significant correlation with leaf folder infestation. Majority of the germplasms which had damage rating of 1 and 3 had rough texture.
