Nymphal survival and development

Studies were undertaken to evaluate the rice genotypes of Sikkim and Tripura for their resistance against brown planthopper (BPH) under glasshouse conditions. Among 74 rice genotypes phenotyped, a genotype (AC-39843) was considered as resistant and two other genotype (AC-39842 and AC-39877) of Tripura were categorized as moderately resistant to BPH. To understand their mechanism of resistance, resistant genotypes were evaluated for different parameter of antixenosis and antibiosis.
