Mapping Population

Location: University of Missouri, Horticulture and Agroforestry Research Center (HARC) in New Franklin, MO

Principal Investigators: Mark Coggeshall (University of Missouri), Jeanne Romero-Severson (Notre Dame), Jennifer Koch (US Forest Service)

A total of 490 full sibs were produced by Jennifer Koch (USFS, Delaware, OH) in the spring of 2014. Due to some outstanding disease issues, we now have 442 live trees that were outplanted in the spring 2015.


Leafing date and bud burst phenotyping on these seedlings began in 2015. This population was created specifically to conduct QTL analyses for Emerald Ash Borer
resistance/tolerance, but no funding is yet in place to do this work. If funds permit, we will graft the population and distribute it to one or more additional plantation sites.

Please contact us for more information or if you are interested in utilizing this population for research. Phenotype information will be posted here when publicly available.
