Hypothesis
Can a new algorithm improve the accuracy of consensus SNP maps in barley?
Conclusion
The R package DAGGER produces a more accurate consensus map for barley than previous methods.
Supporting Evidence
- DAGGER produced a consensus map with improved fine structure compared to the existing barley consensus SNP map.
- The RMS error between the linkage maps and the DAGGER map was 0.82 cM per marker interval.
- DAGGER is a freely available resource for integrating information from consistent linkage maps.
Takeaway
Scientists created a new tool called DAGGER that helps make better maps of barley genes, which can help in plant breeding.
Methodology
DAGGER uses linear and quadratic programming to create consensus maps from multiple linkage maps.
