dc.description | Salah satu penyakit penting yang sangat merugikan tanaman kenaf adalah penyakit layu Fusarium yang disebabkan oleh Fusarium oxysporum Schlecht. Tujuan penelitian ini adalah untuk mengevaluasi tingkat ketahanan aksesi kenaf terhadap jamur Fusarium oxysporum. Penelitian dilakukan di laboratorium dan rumah kasa Balai Penelitian Tanaman Pemanis dan Serat, Malang menggunakan rancangan acak lengkap) yang diulang tiga kali. Dalam evaluasi ini digunakan 70 aksesi dan 1 aksesi tahan (BG-52-135) yang digunakan sebagai kontrol. Inokulasi dilakukan pada 7 hari setelah tanam (HST) menggunakan suspensi spora dengan kerapatan105/ml sebanyak 100 ml setiap bak. Pengamatan intensitas serangan dilakukan mulai 10–40 hari setelah inokulasi (HSI) dengan interval pengamatan lima hari. Pengamatan persentase diskolorisasi batang dilakukan sekali pada 50 HSI. Hasil pengujian memperoleh 1 aksesi (FJ/017) sangat tahan dengan intensitas serangan terrendah (0,83%) dan 14 aksesi tahan dengan intensitas serangan <10%, 28 aksesi dengan ketahanan moderat, dan 27 aksesi yang rentan terhadap infeksi F. oxysporum. Aksesisi FJ/017 (aksesi yang sangat tahan) dan 14 aksesi yang tahan: 1064(SUC/012), 1061(SRB/082), 1035(FJ/005), 839(PARC/2709), 955(FJ/003), 842(PARC/2712), 1095(SUC/003), 838(PARC/2708), 957(FJ/ 007), 1065(SUC/023), 1042(CHN/056), 145(BL/118), 1036(FJ/006), dan 778(PARC/2466) dapat digunakan sebagai sumber ketahanan pada perakitan varietas baru. One of the important disease that very detrimental to kenaf is Fusarium wilt caused by Fusarium oxysporum Schlecht. The purpose of this study was to evaluate the response of 70 kenaf germplasms accessions against F. oxysporum. The study was conducted at the Phytopatology Laboratory and screen house of Indonesian Sweetener and Fiber Crops Research Institute, Malang using completely randomized design with three replicates. Seventy accessions and one resistant accession as control (1267 (BG-52-135) were used in this study. Inoculation of Fusarium was done 7 days after sowing (das) by sprinkling 100 ml of spore suspension into the soil. Observation of disease intensity started at 10–40 days after inoculation (dai) and repeated every five days. Percentage of stalk discolorization was estimated at 50 dai. The results showed that accession 1040 (FJ/017) had the lowest disease intensity (0.83%), hence was categorized as a highly resitant accession. Fourteen accessions were categorized as resistant with disease intensity below or equal to 10%; 28 accessions were moderate resistant; and 27 accessions were susceptible. FJ/017 (the highset resistant accession) and 14 resis-tant accessions (1064(SUC/012), 1061(SRB/082), 1035(FJ/005), 839(PARC/2709), 955(FJ/003), 842(PARC/ 2712), 1095(SUC/003), 838PARC/2708), 957(FJ/007), 1065(SUC/023), 1042(CHN/056), 145(BL/118), 1036 (FJ/006), dan 778(PARC/2466)) could be used as resistant genetic sources in developing new varieties. | en-US |
