Resumo: 	The major rainfed rice growing area in the Lower North region of Thailand has good soil fertility. It has high potential to produce good rice varieties including aromatic rice. However, at present, Nahng Mon S-4 is the only aromatic, intermediate amylose content rice variety being officially released. Therefore, a selection for an aromatic, intermediate amylose content, high yield and resistant to major disease and insect pest is needed to provide the alternative for farmers. The promising line designated PSL04106-28-1-2-1-1-1 was obtained the double cross being HPSL1/Mudgo//HSRN/SPR90116-15-2-2-1-1///SPR90116-15-2-2-1-1 during 2002-2004.  F1 and F2 were massively sown in 2005-2006, respectively. F3 and F4 were tested against brown plant hopper (BPH) during 2007-2008 and resistant plants were selected for rapid generation advance (RGA), after which the plants were grown as F5-F6. Blast resistance screening was conducted and selected plants were passed through the step of RGA. F7 was sown in 2008 and observation trial was carried out in 2009 after which the line PSL04106-28-1-2-1-1-1 was selected. Intra-station yield trial was carried out in 2010 followed by Inter-station yield trial and yield stability trial during 2011-2012. Also, in the year 2012, farmers’ field yield trials and nitrogen fertilizer application experiment were concurrently conducted. This promising line PSL04106-28-1-2-1-1-1 is a photosensitive, non-glutinous rice line having medium maturity being harvested towards the end of November providing an average grain yield of 728 kg/rai. It has a rather upright tillers, strong culm, green leaves, upright flag leaf, rather short neck, medium-packed panicle. The average height is 125 cm. The paddy grain weight is 11.35 kg/thang. One-thousand grain weight is 32.67 g. The seed has a straw color and straw with brown speckles. The seed dimension is 10.15 x 2.19 x 2.17 mm for length x width x thickness, respectively. The brown rice has a slender shape having length x width x thickness as 7.76 x 2.39 x 1.89 mm, respectively. The grain dimension is 7.74 x 2.35 x 1.85 mm for length x width x thickness, respectively. It is classified as intermediate amylose content group (22.2%), soft-medium gel consistency, low gelatinization temperature and less elongation ratio. Cooked rice is aromatic, glossy and white in color. It’s texture is as soft as Nahng Mon S-4 but less than KDML105. Seed dormancy is 7-8 weeks. This promising line is recommended for the rainfed area in the Lower North and Central plain. It’s agronomic characters comprise of an intermediate maturity having the advantages as high yield and resistance to rice blast.
