dc.descriptionABSTRAK. Penyakit karat putih adalah salah satu kendala dalam meningkatkan produksi bunga krisan. Penyakit karat putih pada tanaman krisan disebabkan oleh cendawan Puccinia horiana. Salah satu alternatif pengendalian adalah menggunakan varietas resisten. Tujuan penelitian adalah mengetahui insidensi dan intensitas penyakit karat putih pada klon-klon krisan. Penelitian dilakukan di Rumah Plastik Balai Penelitian Tanaman Hias di Segunung (1.100 m dpl.), sejak bulan September 2002 sampai Februari 2003. Pada penelitian ini dievaluasi sebanyak 13 klon harapan krisan hasil seleksi tahun 2000. Perlakuan terdiri 13 klon harapan krisan yaitu klon nomor 116.44, 116.53, 116.57, 125.14, 130.8, 131.1, 133.59, 133.7, 133.95, 135.6, 136.1, 136.11, 150.4, var. Saraswati, dan var. White Reagent, menggunakan rancangan acak kelompok dengan 3 ulangan. Hasil penelitian menunjukkan bahwa klon nomor 136.10 adalah klon yang memiliki sifat baik, paling lambat terinfeksi penyakit karat (133 HST), pada 15 MST paling rendah insiden penyakitnya (12,67%). Intensitas serangan kedua terendah (5,08%) setelah klon nomor 133.95 (4,6%), dan intensitas penyakit waktu panen juga rendah (4,44%).ABSTRACT. Rahardjo I.B. and Suhardi. 2008. Incidence and Intensity of White Rust Disease on Several Chrysanthemum Clones. White rust disease is one of constrain in increasing the production of chrysanthemum flower. White rust disease on chrysanthemum caused by Puccinia horiana. One of the control alternative was the use of resistant variety. The aim of the experiment was to know incidence and disease intensity of white rust on chrysanthemum clones. The experiment was done in Plastichouse at Indonesian Ornamental Crop Research Institute, Segunung (1.100 m asl), from September 2002 to February 2003. Evaluations were done on 13 chrysanthemum promising clones from selection in 2000. The treatments consisted of 13 chrysanthemum promising clones namely : 116.44, 116.53, 116.57, 125.14, 130.8, 131.1, 133.59, 133.7, 133.95, 135.6, 136.1, 136.11, 150.4, var. Saraswati, and var. White Reagent. RCBD with 3 replications were used in this experiment. The results of the experiment showed that clone 136.10 indicated good characteristic, with latest of disease infection (133 days after planting), lowest disease incidence at 15 weeks after planting (12.67%), and the second lowest for disease intensity (5.08%) after clone 133.95 (4.6%). While clone 136.10 showed lowest disease intensity on harvesting time (4.44%).en-US
