GSOR 104301-104513

The L-202 × Trembese rice (Oryza sativa L.) mapping population was developed from the Rice Diversity Panel 1 accessions L-202 (GSOR 301090) originating from California, USA, and Trembese (GSOR 301156) originating from Indonesia. Genotyping classified both parents as tropical japonica. Both accessions were characterized as phenotypically and genotypically diverse from each other. The population consists of 211 F2:9 recombinant inbred lines (RILs) and parents (GSOR 104301 through GSOR 104513), which were genotyped with 1,439 polymorphic SNP markers selected from the Cornell-IR LD Rice Array (C7AIR) and four simple sequence repeat (SSR) markers. The population was phenotyped for 20 yield component traits including seven agronomic traits (days to heading, plant height, culm habit, awn presence, seed shattering, lodging and panicle number per plant), seven panicle architecture traits (panicle length; number of primary and secondary branches, number of florets, seeds, and sterile florets per panicle; and percent fertility), and six seed traits (seed length, width, and length-to-width ratio with the hull, 100-seed weight, seed weight per plant and seed weight per panicle).
