Abstract
The brown planthopper (BPH) is one of the major pests of rice that causes significant losses. One of the control efforts against BPH is using resistant varieties. Local rice varieties serve as germplasm resources that can be utilized to develop resistant varieties. This research aims to identify the resistance of four local rice varieties from Banten to BPH and to identify the biotype of the tested BPH insect used in this study. The study was conducted from November 2018 to April 2019 at the greenhouse of the Banten Assessment Institute for Agricultural Technology. Resistance identification against BPH was performed on Banten local rice varieties: Gadog, Rabig, Ketan Gadung, and Apel Merah, with TN1 used as a susceptible control variety. Resistance testing used BPH field populations from Pontang District, Serang Regency, on 7-day-old seedlings. Furthermore, biotype identification of the BPH insect was conducted using differential varieties: TN1, Mudgo, ASD7, and Rathu Heenati. BPH biotype determination followed the Standard Evaluation System for Rice by IRRI. The results of the resistance testing showed that Gadog rice was highly susceptible, Rabig and Ketan Gadung were susceptible, and Apel Merah was resistant to the tested BPH population. The identification of the test insect revealed biotype 2.
