Abstract

Sorgum merupakan salah satu tanaman serealia yang banyak mengandung karbohidrat. Rhizoctonia solani merupakan salah satu patogen tular tanah yang mampu menggagalkan panen sorgum. Penelitian bertujuan untuk mempelajari respon beberapa galur sorgum koleksi Balai Penelitian Kacang - kacangan dan Umbi - umbian (Balitkabi) terhadap cendawan R. solani. Penelitian dilaksanakan mulai Oktober 2012 sampai Juni 2013 di laboratorium dan rumah kasa hama penyakit Balai Penelitian Kacang – kacangan dan Umbi – umbian (Balitkabi). Penelitian menggunakan Rancangan Acak Kelompok (RAK), 12 galur sorgum dengan perlakuan inokulasi cendawan R. solani diulang sebanyak 3 kali untuk tiap galurnya,  sedangkan untuk kontrol yaitu tanpa pemberian cendawan. Data dianalisis menggunakan program SPSS 16.0 for Windows. Hasil penelitian menunjukkan bahwa masa inkubasi cendawan R. solani berlangsung dari 4 sampai 42 hari. Diperoleh tiga galur sorgum yang menunjukkan masa inkubasi terpendek, yaitu galur nomor 3 (4 hari), 4 (5 hari), dan 10 (6 hari). Berdasarkan tingkat serangan R. solani mengindikasikan bahwa galur nomor 1, 6, 7, 8 dan 12 merupakan galur yang sangat tahan terhadap cendawan R. solani. Galur rentan tidak didapatkan dalam penelitian ini.
