Selection and Evaluation of Several BC2F2 Rice Accession Tolerance to Submergence Stress and Backcrossing to Local Parent

Abstract

This study aimed to conduct selection process upon the four accessions of BC2F2 rice genotypes which were tolerant to submergence stress during vegetative stage. The selected plants were crossed with local parents. Local parents which were used in this experiment consisted of Payak Silembuk, Siam, Pegagan, and Pelita Rampak. BC2F2 Accession (BC2F2Py.Silembuk, BC2F2Siam, BC2F2Pegagan, and BC2F2P.Rampak) were evaluated before and after submerging process. The data obtained was analyzed with the Least Significant Difference (LSD) formula. The results showed that BC2F2Py.Silembuk accession had better tolerance compared to the rest of accessions being observed. Hence, this study concluded that the accession of BC2F2Py.Silembuk shows the best performance among the others of BC2F2 accesions. The result of back crossing to local parent, accession of BC2F2Py.Silembuk gave the best result.
