Daftar Isi:
- Kerebahan menyebabkan penurunan produksi tanaman padi. Tanaman padi tahan rebah dapat dihasilkan dari kegiatan pemuliaan tanaman. Tujuan penelitian adalah seleksi galur F4 tahan rebah. Penelitian dilaksanakan pada bulan Desember 2018 hingga Mei 2019 di lahan ultisol, Kabupaten Bangka, Provinsi Kepulauan Bangka Belitung. Penanaman galur dilakukan secara single plant. Metode seleksi yang digunakan adalah seleksi pedigree. Hasil penelitian menunjukkan bahwa karakteristik galur F4 padi terseleksi memiliki tinggi tanaman kurang dari 90 cm. Terdapat 70 galur F4 terseleksi memiliki ketahanan rebah berdasarkan karakter tinggi tanaman dan didukung oleh karakter diameter batang, panjang malai, kekuatan batang, dan berat biji bernas per rumpun.
- Lodging of the paddy plants causes a decrease in rice plant production. Lodging resistants rice plants can be produced through plant breeding. The purpose of the research is selection lodging resistant F4 lines. The research was carried out from December 2018 to May 2019 in the ultisol field, Bangka Regency, Bangka Belitung Province. The F4 lines were planted by a single plant design. Plants were selected using the pedigree method. The result showed that the characteristics of rice F4 lines from crossed were less than 90 cm of height and 70 selected F4 lines seemed to have lodging resistance based on the plant height character and also supported by stem diameter, panicle height, stem strength, and pithy seeds weight per clump.
