Screening of rice germplasm for resistance and susceptibility against yellow stem borer (Scripophaga incertulas walker) under upland rice ecosystem

Author(s): MK Mishra and RP Singh
Abstract: Eighteen rice germplasm were evaluated against yellow stem borer (Scripophaga incertulas Walker) infestation, to estimate the reaction under field condition during Kharif, 2007 and 2008. The infestation of YSB in all the germplasm was found lower than the check variety, Vandna. However, at late tillering stage, all the germplasm were found to be resistant except Vandna which showed moderately resistant reaction. At maturity stage, only eight germplasm viz., RR 427-100, NDR 1018-1, RR 366-4, NDR 97-12, NDR 1087-10, NDR 97 and RR 270-3 were found resistant against YSB. Seven germplasm viz., RR 270-2, RR 3470-5, NDR 1091-2, Shusk Samrat, RR 270-5, RR 309-5 and Anjali showed moderately resistant reaction, while three germplasm had shown moderately susceptible reaction including the check. It is to fact that yellow stem borer is not act as the major pest borer in upland rice ecosystem, though it preferred aquatic environment.
