- Summary:
-
-
-
- The Col x Bur genetic reference population consists of approximately 347 recombinant inbred lines (RIL). This set was created by Olivier Loudet and colleagues between 2003 and 2006 at the INRA in Versailles, France. Arabidopsis has a genome consisting of five chromsomes and a total of 125 megabases of DNA, equivalent in length to a single human chromosome. However, the genome is nonetheless rich and contains approximately 26,000 genes. Full sequence data are available for this species. (The Col-0 accession was sequenced.)
-
-
-The RILs were derived from a cross between Col-0 (Columbia, USA, accession N1092) and Bur-0 (Burren, Ireland, accession N1028); two accessions obtained from the NASC European Arabidopsis Stock Centre. Col and Bur were chosen because of their well characterized genetic, geographical, and ecological differences. Lines were propagated by single seed descent through the sixth generation (F6) without selection. One plant per line was then used for genotyping (347 RILs x 87 markers) and selfed to obtain F7 seeds. F8 seed stock generated by bulk multiplication of F7 plants are available for analysis. Data sets in WebQTL include up to 415 ColXBur accessions and the two parental stock.

- About the genotypes used in these studies:
-
-
-This production of the ColXBur Arabidopsis genotype data set is described in Loudet and colleagues (in progress). This marker data set consists of 87 markers for all strains. It is used to map QTLs for phenotypes listed in the ColXBur Published Phenotypes data set.
