ABSTRACT
Medina Shafira. 2016. “Resistence Test of Sugarcane (Saccharum officinarum) Varieties by Pokkah boeng Disease (Fusarium moniliforme) at Green House”. Supervised by Lahmuddin Lubis and Maryani Cyccu Tobing. Pokkah boeng is one of the most important disease on sugarcane and this disease can reduce sugar production in Indonesia. This research was study to determine resistence of sugarcane plant varieties against Fusarium moniliforme at green house. This research had been conducted at green house of Universitas Sumatera Utara for March-September 2016 using completely randomized design (CRD) nonfactorial with ten varieties (BZ 134, PS 851, PS 881, PS 862, PS 864, VMC 76-16, Kentung, TLH 1, PS 882, PSDK 923) and three replications. The results showed that all of the varieties of sugarcane plant was infected by Fusarium moniliforme. Nine of Sugarcane varieties were very susceptible (BZ 134, PS 851, PS 881, PS 862, PS 864, VMC 76-16, Kentung, PS 882, and PSDK 923) and susceptible at TLH 1.
Key words : Fusarium monilifome, plant resistence, sugarcane, varieties
ABSTRAK
Medina Shafira. 2016. ”Uji Ketahanan Beberapa Varietas Tebu (Saccharum officinarum) Terhadap Penyakit Pokahbung (Fusarium moniliforme) di Rumah Kaca”. Di bawah bimbingan Lahmuddin Lubis dan Maryani Cyccu Tobing. Pokahbung merupakan salah satu penyakit penting pada pertanaman tebu yang dapat menurunkan produksi gula di Indonesia. Penelitian ini bertujuan untuk mengetahui ketahanan beberapa varietas tebu terhadap penyakit pokahbung di rumah kaca. Penelitian dilaksanakan di rumah kaca fakultas petanian Universitas Sumatera Utara pada bulan Maret-September 2016 menggunakan rancangan acak lengkap non faktorial dengan sepuluh varietas (BZ 134, PS 851, PS 881, PS 862, PS 864, VMC 76-16, Kentung, TLH 1, PS 882, PSDK 923) dan tiga ulangan. Hasil menunjukkan seluruh varietas dapat terinfeksi oleh Fusarium moniliforme. Sebanyak sembilan varietas (BZ 134, PS 851, PS 881, PS 862, PS 864, VMC 76-16, Kentung, PS 882, dan PSDK 923) memiliki ketahanan sangat rentan dan dengan ketahanan rentan di varietas TLH 1.
Kata Kunci : Fusarium moniliforme, ketahanan tanaman, tebu, varietas
