GSOR 104001-104282

The Estrela × NSFTV199 rice (Oryza sativa L.) mapping population (Reg. no. MP-8, NSL 530337 MAP) was developed from the Rice Diversity Panel 1 accessions Estrela (GSOR 301227) originating from Colombia, classified as an admixture of japonica, and NSFTV199 (GSOR 301190) of unknown origin classified as tropical japonica. Both accessions were characterized as phenotypically and genotypically diverse from each other. The population consists of 276 F2:9 recombinant inbred lines (RILs) and parents (GSOR 104001 through GSOR 104282), which were genotyped with 65 simple sequence repeat (SSR) markers and 256 RILs genotyped with an additional 69 SSR markers. The population was phenotyped for 23 yield component traits including eight agronomic traits (days to heading, plant height, flag leaf length and width, leaf pubescence, culm habit, awn presence, and seed shattering), six panicle architecture traits (panicle length; number of primary branches, florets, seeds, and sterile florets per panicle; and percentage fertility), and nine grain traits (seed length, width, and length-to-width ratio with and without the hull; percentage chalk in brown rice with and without the broken kernels, and 100-seed weight).
