|---|---|---|---|
| Weber et al. (2001)/Weber et al. (1999) | Zimmerman et al. (2000) | This study | |
| Strains/design | Recombinant chromosomes from high-/low-index F lines (low background) | RILs derived from Oregon R × Russian 2b |
RILs derived from two wild-type parents (Winters, CA) |
| No. possible alleles per locus | 2 | 2 | 4 |
| Marker coverage per centimorgan, CHR2/CHR3 |
2.3/1.8 | 4.1/2.6 | 2.4/1.7 |
| Map distances | Genes close to markers | RIL markers | RIL markers |
| Estimated using traits | F-index (ratio of widths) | Landmarks | Landmarks |
| Analysis method | MIM | CIM | CIM |
Average distance between markers assumes 110 cM for CHR2 and 111 cM for CHR3. The average distance between markers for Zimmerman et al. (2000) includes all markers listed in Nuzhdin et al. (1997). MIM, multiple-interval mapping; CIM, composite-interval mapping.
