Evaluasi Pertumbuhan dan Seleksi Tanaman Padi Aksesi BC2F2 Toleran Cekaman Terendam Serta Persilangan balik-nya dengan Tetua Lokal

Abstract

Hasmeda et al, 2017. Growth Evaluation and Selection of Several BC₂F_{2 Â} Rice Accession Tolerant to Submergence Stress and Their Backcrossing to Local Parent. JLSO 6(1):7-20.

 

This study was aimed to conduct selection process upon the four accessions of BC₂F₂ rice which were tolerant to submerging stress during vegetative stage. The selected plants were crossed with local parents. Local parents being used in this experiment consisted of Payak Silembuk, Siam, Pegagan, and Pelita Rampak.  There were several backcrossing being observed i.e. BC₂F₂ Accesion (BC₂F₂Py.Silembuk, BC₂F_2.Siam, BC₂F_2.Pegagan, and BC₂F₂P.Rampak) which were evaluated on the 20th day after being planted for 14 days. Parameters were observed before and after submerging process. The data obtained were analyzed with the Least Significant Difference (LSD) formula. As the result, BC₂F₂Pys accession had better tolerance compared with the rest of accessions and showed consistent resultsas the previous research. It is concluded that the accession of BC₂F₂Py.Silembuk showed the best performance among the other  of BC₂F₂.
