N2 - Two mapping populations were developed from crosses of the Asian indica rice (Oryza sativa L.) cultivar ‘Dee Geo Woo Gen’ (DGWG; PI 699210 Parent, PI 699212 Parent) and two weedy rice ecotypes, an early-flowering straw hull (SH) biotype AR-2000-1135-01 (PI 699209 Parent) collected in Arkansas and a late-flowering black hull (BHA) biotype MS-1996-9 (PI 699211 Parent) collected in Mississippi. The weed and crop-based rice recombinant inbred line (RIL) mapping populations have been used to identify genomic regions associated with weedy traits as well as resistance to sheath blight and rice blast diseases. The mapping population consists of 185 (DGWG/SH; Reg. no. MP-9, NSL 541035 MAP) and 234 (BHA/DGWG; Reg. no. MP-10, NSL 541036 MAP) F8 RILs, of which 175 (DGWG/SH) and 224 (BHA/DGWG) were used to construct two linkage maps using single nucleotide polymorphic markers to identify weedy traits, sheath blight, and blast resistance loci. These mapping populations and related datasets represent a valuable resource for basic rice evolutionary genomic research and applied marker-assisted breeding efforts in disease resistance.
