  abstract = {{B}ackground: {D}eveloping new population types based on interspecific introgressions has been suggested by several authors to facilitate the discovery of novel allelic sources for traits of agronomic importance. {C}hromosome segment substitution lines from interspecific crosses represent a powerful and useful genetic resource for {QTL} detection and breeding programs. {R}esults: {W}e built a set of 64 chromosome segment substitution lines carrying contiguous chromosomal segments of {A}frican rice {O}ryza glaberrima {MG}12 (acc. {IRGC}103544) in the genetic background of {O}ryza sativa ssp. tropical japonica (cv. {C}aiapo). {W}ell-distributed simple-sequence repeats markers were used to characterize the introgression events. {A}verage size of the substituted chromosomal segments in the substitution lines was about 10 c{M} and covered the whole donor genome, except for small regions on chromosome 2 and 4. {P}roportions of recurrent and donor genome in the substitution lines were 87.59% and 7.64%, respectively. {T}he remaining 4.78% corresponded to heterozygotes and missing data. {S}trong segregation distortion was found on chromosomes 3 and 6, indicating the presence of interspecific sterility genes. {T}o illustrate the advantages and the power of quantitative trait loci ({QTL}) detection using substitution lines, a {QTL} detection was performed for scored traits. {T}ransgressive segregation was observed for several traits measured in the population. {F}ourteen {QTL}s for plant height, tiller number per plant, panicle length, sterility percentage, 1000-grain weight and grain yield were located on chromosomes 1, 3, 4, 6 and 9. {F}urthermore, a highly significant {QTL} controlling resistance to the {R}ice stripe necrosis virus was located between {SSR} markers {RM}202-{RM}26406 (44.5-44.8 c{M}) on chromosome 11. {C}onclusions: {D}evelopment and phenotyping of {CSSL} libraries with entire genome coverage represents a useful strategy for {QTL} discovery. {M}apping of the {RSNV} locus represents the first identification of a genetic factor underlying resistance to this virus. {T}his population is a powerful breeding tool. {I}t also helps in overcoming hybrid sterility barriers between species of rice.},
