EXPLORING THE LANDRACE RICE (ORYZA SATIVA L) FOR SALINITY TOLERANT AND AGRONOMIC TRAITSNafisah, Celvia Roza, Nani Yunani, Rahmini and Priatna Sasmita
Rice genotype tolerant to salinity at seedling stage with high yield potential is very desirable to over come the saline soil problem in a coastal area in the early monsoon. A total of one hundred and fifty four rice accessions were evaluated for salinity tolerance at the seedling stage at 12 d Sm-1 in screen house using Yoshida salinized solution for sixteen days. A total of 47 accessions having survived seedling were transferred to media non-saline and grown until harvesting to have some seed for evaluation of agronomic traits and resistant to Xoo pathotype IV in the following season. There were eight accessions showed tolerant to salinity at 12 d Sm-1 which were Talun Bagang (1783), Talun Bintik (1786), Padi Sawah Ngale (1790), Ketan (4578),Nongkong Jambu (4588), Pulut Kemuken (4598), and Gadis Kuning (4591). There were two accessions, i.e.Pulut Kuning (3321) and Serepet Tinggi (3928) showed resistant to Xoo pathotype IV under field screen condition. Three accessions, Nongkong Jambu (4588), Pulut Kemuken (4598), Gadis Kuning (4591), had a good agronomic trait which were very potential to be used as a parent to improve high yielding tolerant to salinity.
