15. Outputs and Uses of MAGIC populations
as of 2013
Methodologies and new
knowledge
• Practical guide to produce
MAGIC —being used to create
additional MAGIC populations
(heat tolerance, biotic stress)
• Workflow for applying GWAS
mpMAP, Flapjack--using GBS
and phenotype data
• QTL for new traits (e.g.
resistance to brown spot)
Available Recombined
populations
• Indica MAGIC S6:8 population,
~1,800 lines
• Japonica MAGIC (S6), 400
lines
• Indica selections from Multi-
Environment Trials, 130 lines
• Global MAGIC (Indica x
japonica). >1500 S6 lines in
2014
• 20 lines with high Yield
Stability Index (YSI)

16. Summary and Future Work
Phenotyping , QTL mapping
Genetic basis of transgressive
segregation
Recombination questions:
LD decay, recombination
breakpoint,
Genome interactions and
epistasis,
Sequenced

Multi-Environment Trials to
evaluate GxE
Identify transgressive
segregations for new (or
enhanced) traits
Distribute to breeding programs

Genetics

17. Activated, “rapid response genetic
resources”
• Sequenced breeding populations
with predictive power on gene-
phenotype relationships (e.g.,
MAGIC, NAM)
• Elite gene pools (in silico) that can
be readily evaluated for new traits

18. As an example: Bacterial leaf streak
disease
MAGIC lines
segregating for
resistance and
susceptibility
