The ILs were derived from crosses between cv Curinga, a tropical japonica upland cultivar, and two different wild donors, Oryza meridionalis Ng. accession (W2112) and Oryza rufipogon Griff. accession (IRGC 105491). The lines were genotyped using genotyping-by-sequencing (GBS) and SSRs. The 32 Curinga/O. meridionalis ILs contain 76.73 % of the donor genome in individual introgressed segments, and each line has an average of 94.9 % recurrent parent genome. The 48 Curinga/O. rufipogon ILs collectively contain 97.6 % of the donor genome with an average of 89.9 % recurrent parent genome per line. To confirm that these populations were segregating for traits of interest, they were phenotyped for pericarp color in the greenhouse and for four agronomic traits-days to flowering, plant height, number of tillers, and number of panicles-in an upland field environment. Seeds from these IL libraries and the accompanying GBS datasets are publicly available and represent valuable genetic resources for exploring the genetics and breeding potential of rice wild relatives. specialized Rice Oryza sativa Crop wild relatives Chromosome segment substitution lines (CSSLs) Allele discovery Marker-assisted selection (MAS) Genotyping by sequencing (GBS) 076 Molecular Breeding 35 2 art. 81 [18 p.] 2015 1380-3743 https://www.documentation.ird.fr/hor/fdi:010063964 10.1007/s11032-015-0276-7 1380-3743 [F B010063964] https://www.documentation.ird.fr/hor/fdi:010063964 https://www.documentation.ird.fr/intranet/publi/2015/04/010063964.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-05-04 2017-08-23 fdi:010063964 fre
