Altogether, 55 promising rice genotypes along with susceptible check variety TN-1 and resistant check variety Suraksha have been screened against yellow stem borer (YSB), Scirpophaga incertulas (Walker) during kharif seasons 2010-11, 2011-12 and 2012-13. The YSB infestation varied from 0.0 to 18.67, 0.67 to 22.83 and 0.0 to 20.58%, respectively, during the kharif seasons 2010-11, 2011-12 and 2012-13. The results clearly indicated that the rice genotypes RP-Bio-Patho-02, BPT-5204 and HR-DRR-02 were most promising and highly resistant with 0.67, 0.78 and 1.22% average YSB infestation in comparison to susceptible check variety TN-1 with 20.69% average YSB infestation. However, average YSB infestation in resistant check variety Suraksha was 5.22%. Also, the entries CB-06-535, RP-4867-52-2-1192, RTNRH-10, CR-2711-76, CR-3005-230-5, TNRH-244, RP-Patho-08, RP-Bio-Patho-01, C 101 LAC, HR-DRR-01, RP 4680-1-2-23, CB 09-538 and CB 10-504 were also promising with 5 to 6.37% average YSB infestation and may be rated as moderately resistant.
