Abstract

Uji Ketahanan Berbagai Varietas padi (0ryza sativa L) Lokal Sumut Pada Fase Vegetatif Terhadap Penyakit Hawar Datm Bakteri (Xanthomonas myzae pv. oryzae)" . Skripsi ini dibawah bimbingan Bapak Dr. Ir. Zulheri Noer, MP selaku ketua dan lbu Ir. Azwana, MP selaku anggota pembimbing. Penelitian bertujuan untuk mengetahui ketahanan varietas padi (Oryza sativa L) lokal Sumut terhadap serangan penyak:it Hawar Daun Bakteri (Xanthomonas myzae pv. myzae) pada fase vegetatif. Penelitian menggunakan Rancangan Acak Lengkap Non Faktorial dengan perlakuan VO = Varietas Ciherang, Vl = Varietas Siurom, V2 = Varietas Sirias, V3= Varietas Simedan, V4 = Varietas Sidampal, V5 = Varietas Sigara-gara, V6 = varietas Si Boru Manusun, V = Varietas Silombu-lombu. Basil penelitian menunjukkan bahwa semua arietas padi (Oryza sativa L) lokal Sumut yang diuji pada penelitian ini rentan terhadap penyakit Hawar Daun, Varietas VO, Vl, V3, V6 dan V7 memiliki kategori sangat rentan sedangkan V2, V4 dan V5 memiliki kategori rentan tehadap Xoo. Resistance Test of Various Local Rice (Oryza sativa L) Varieties from North Sumatra at the Vegetative Stage Against Bacterial Leaf Blight Disease (Xanthomonas oryzae pv. oryzae). This thesis was carried out under the supervision of Dr. Ir. Zulheri Noer, MP as the main advisor, and Ir. Azwana, MP as the co-advisor. The objective of this research was to determine the resistance of local rice (Oryza sativa L) varieties from North Sumatra to bacterial leaf blight disease (Xanthomonas oryzae pv. oryzae) during the vegetative stage. The study employed a Non-Factorial Completely Randomized Design with the following treatments: V0 = Ciherang variety, V1 = Siurom variety, V2 = Sirias variety, V3 = Simedan variety, V4 = Sidampal variety, V5 = Sigara-gara variety, V6 = Si Boru Manusun variety, and V7 = Silombu-lombu variety. The results showed that all tested local rice (Oryza sativa L) varieties from North Sumatra were susceptible to bacterial leaf blight. Varieties V0, V1, V3, V6, and V7 were categorized as highly susceptible, while V2, V4, and V5 were categorized as susceptible to Xoo.
