The aim of the study was to determine the growth performance and resistance of four new superior varieties (NSV) against rice stem borer (RSB). The variables observed were agronomic and yield components, harvested dry grain (HDG), the incidence and attack rate of RSB every 2 weeks. The research was designed on a randomized block design (RBD) by using four NSV, namely Inpari 16, 32, 33, and Ciherang as control with 6 replications. The data were analyzed using Analysis of Variance (ANOVA), if there was a difference between the mean values, it was continued with a 5% LSD test. The research results showed that the use of Inpari 16, 32, and 33 increased crop yield by up to 6,9% to 30,9%. The highest yield was achieved by a variety of Inpari 32 (8,82 tons per hectare), followed by Inpari 33 (7,51 tons per hectare), and the lowest yield was found for Inpari 16 (6,95 tons per hectare). This shows that the use of Inpari 16, 32, and 33, can increase the percentage of rice production 6.92%, 35.62%%, and 15.54% respectively. The results showed that the three varieties inpari 16, 32, and 33 were susceptible to mild damage (≤ 11%), namely 0.56%, 0.6%, and 0.23% respectively, while Ciherang (control) 0.45%.
