Defensive Responses of Rice Genotypes Against Yellow Stem Borer, Scirpophaga incertulas (Walker)
Year: 2024
Type: article
Abstract: The response of rice genotypes to yellow stem borer Scirpophaga incertulas (Walker) infestation under natural climatic conditions was evaluated during kharif 2018-19 and 2019-20 at BHU, Varanasi. Findings revealed that deadhearts and white earheads caused by S. incertulas (Walker) varied significantly, indicating the presence of resistance-susceptibility. The dead hearts was significantly lower in resistant genotypes BRRI DHAN-64 (1.49%) and IR82475-110-2-2-1-2 (2.00%). The susceptible TN1 (17.45%), Swarna (14.98%), and IR-92960-75-1-3 (14.58%) had the highest amount of deadhearts. The least white earheads was recorded in IR82475-110-2-2-1-2 (1.16%) and AKSHYADHAN (1.19%), however the maximum percent of white earheads was observed in TN1 (13.37%), SWARNA (11.22%) and IR-92960-75-1-3 (9.87%). Infestation was significantly and positively correlated with total sugar, crude protein andtotal free amino acid; showed significant negative correlation with phenol, crude silica tannin.
