padi beras merah, penyakit blas, ketahananAbstract
Kendala dalam budidaya tanaman padiadalah adanya serangan patogen seperti cendawan Pyricularia oryzae Cav. penyebab penyakit blas. Penggunaan varietas yang tahan penyakit blas adalah solusi yang efektif untuk meningkatkan produksi. Hal ini karena beragamnya ras penyakit blas yang berkembang, salah satunya yang paling virulen adalah ras 173. Untuk menghasilkan varietas padi yang tahan, diperlukan gen tahan penyakit blas yang bersumber dari genotip lokal padi beras merah. Penelitian ini bertujuan untuk menguji ketahanan 5 genotip lokal padi beras merah, mengetahui keragaman dan menduga apakah sifat tersebut dapat diwariskan. Penelitian dilaksanakan pada bulan Februari – Mei 2014, di desa Ketawang, kecamatan Gondanglegi, kabupaten Malang. Bahan yang digunakan adalah 5 genotip lokal padi beras merah dan 2 varietas cek. Penelitian ini menggunakan rancangan IRRI SES. Hasil penelitian menunjukkan genotip Mandel memiliki penampilan terbaik pada semua karakter ketahanan seperti periode laten, skor tingkat ketahanan dan intensitas serangan penyakit.
