Resumo: | Brown planthopper resistant promising line, SPR94007-PTT-27-2-9-3-2, is photoperiod insensitive line derived from single cross of SPR1/IR64 made at Suphan Buri Rice Research Center in 1994. Its F2-F6 progenies had been grown and selected at Pathum Thani Rice Research Center where fixed line, SPR94007-PTT-27-2-9-3, were obtained. In 2008, this line and other breeding lines  were tested for brown planthopper (BPH) resistance and intra-station yield trial. SPR94007-PTT-27-2-9-3 was not selected to be tested in further step due to its unsatisfied yield, but it was only 1 of 2 lines that had no damage of BPH in greenhouse testing. Thus, remained seedlings of those 2 lines had been transplanted in pots and separately harvested panicle by panicle and pedigree designated. Seeds of each panicle were divided into 2 parts to be re-tested for BPH resistance in greenhouse and accordingly transplanted in the field during wet season 2009. It was found that there were 2 lines resistant to BPH at the reaction level of MR-R. Seeds of those corresponded BPH resistant lines in the field, SPR94007-PTT-27-2-9-3-1 and SPR94007-PTT-27-2-9-3-2, had been harvested and multiplied. Then, SPR94007-PTT-27-2-9-3-2 were selected for further tested due to its better agronomic characters. During 2011-2012, SPR94007-PTT-27-2-9-3-2 gave average yield of 641 1,008 and 850 kg/rai by Inter-station yield trial, yield stability trial and farmer’s field yield trial in hot spot of BPH outbreak, respectively. SPR94007-PTT-27-2-9-3-2 had maturity duration of 117-120 days, 115-120 cm plant height, intermediate strong erect culm, green color and erect leaf. Its flag leaf length and width were 46.5 and 1.38 cm, respectively. Its panicle was intermediate exerted, medium in compactness and 25.7 cm long. Its grain had straw color husk and easily shatter. Its brown rice had slender shape with dimension of 7.35 x 2.17 x 1.85 mm in length x width x thickness. Its endosperm contained high amylose content of 27% and soft gel. It was considered to be suitable for irrigated area of the Central Plain where BPH epidemic often occur.
