Abstract
Resistance of Swampy Rice Lines to Brown Plant Hopper. There were a total of 9.5 million ha swampy areas potential to be utilized as a productive agriculture land. The main constrain in the areas were abiotic and biotic in nature. In those areas the rice plants usually grown were local varieties and the yields were low. To obtain rice varieties resistant to the brown plant hopper and have good yield potential, a greenhouse studies have been conducted at Muara Experimental Station, the ICRR, during the year of 2007 and 2008 by the method of seedling box screening test. The rice lines tested were those selected from the early yield test (EYT) and the multi-location test (MLT) trials. The tested lines were infested with the brown planthopper biotype 2 and 3 which have been reared in the Green House of Muara Experimental Station. Results of the screening indicated that the lines of B9858D-KA-55, IR70213-9-CPA-12-UBN-2-1-3-1, and IR70215-2-CPA-2-1-UBN-1-2 were moderately resistant to the BPH biotype 2 and biotype 3, while the line IR70181-5-PM1-1-2-B-1 was resistant to biotype 3 and moderately resistant to biotype 2.

Ketahanan varietas padi rawa yang ada sekarang terhadap wereng cokelat (Nilaparvata lugens Stal) perlu diuji untuk mendapatkan varietas padi yang tahan terhadap wereng cokelat (WCK). Uji ketahanan beberapa galur padi yang berasal dari Kelti Pemuliaan, BB Padi telah dilakukan di rumah kaca KP Muara, Bogor, BB Padi pada MT 2007 dan 2008. Galur padi yang diuji disemai dalam seedling box screening test, kemudian diinfestasi dengan WCK biotipe 3. Hasil pengujian menunjukkan bahwa galur yang agak tahan terhadap WCK biotipe 3 adalah B9858D-KA-55, IR70213-9-CPA-12-UBN-2-1-3-1, dan IR70215-2-CPA-2-1-UBN-1-2. Sementara galur IR70181-5-PM1-1-2-B-1 menunjukkan reaksi tahan dan agak tahan berturut-turut terhadap WCK biotipe 3 dan 2.
