Keragaan Tanaman Padi BC2F2 Tinggong dan Swarna Pada Perlakuan Perendaman

Abstrak. Penelitian ini bertujuan untuk mengetahui tinggi tanaman dan hasil produksi padi BC2F2 Tinggong dan Swarna. Penelitian ini dilaksanakan di Kebun Percobaan dan Laboratorium Ilmu Pemuliaan Tanaman Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh sejak November 2020 hingga Juli 2021. Penelitian ini menggunakan media tanam tanah dan pupuk kandang dengan perbandingan 2:1. Benih yang digunakan dalam penelitian ini adalah benih padi BC2F2 yang terdiri dari genotipe T41.8 dan T41.9. Hasil penelitian menunjukkan bahwa tanaman padi BC2F2Tinggong dan Swarna yang prospektif untuk diuji pada tahap lanjut yaitu genotipe T41.8 (3, 7, 9 dan 11) dan T41.9 (3, 5, 6, 12 dan 16), karena tanaman tersebut memiliki tinggi tanaman yang berbatang pendek dan komponen hasil yang tinggi. Hasil pengujian tahan rendaman menunjukkan bahwa setelah dilakukannya pemulihan (recovery) pada padi BC2F2 Tinggong and Swarna, terdapat 13 tanaman yang hidup dan terdapat 3 tanaman tidak tahan rendaman.Performance Rice Plants of BC2F2 Tinggong and Swarna in the immersion treatmentAbstract. This study aims to determine the plant height and yield of BC2F2 Tinggong and Swarna rice. This research was conducted at the Experimental Garden and Plant Breeding Science Laboratory, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh from November 2020 to July 2021. This study used soil and manure planting media in a ratio of 2:1. The seeds used in this study were BC2F2 rice seeds consisting of genotypes T41.8 and T41.9. The results showed that the Tinggong and Swarna derived BC2F2 rice plants that were prospective to be tested at an advanced stage were genotypes T41.8 (3, 7, 9 and 11) and T41.9 (3, 5, 6, 12 and 16). It has a short plant height and a high yield component. The results of the immersion resistance test showed that after recovery in BC2F2 Tinggong and Swarna, there were 13 plants that were alive and there were 3 plants that were not resistant to immersion.
