Project Type: Trust Fund Cooperative Agreement
Start Date: Mar 1, 2010
End Date: Feb 28, 2013
The objectives of this project are 1) conduct a QTL analysis of fire blight resistance in the Malus sieversii GMAL4593 mapping population; 2) identify M. sieversii-specific SNPs to add additional markers to the genetic map of M. sieversii; and 3) establish plantings of M. sieversii in Washington and West Virginia for the identification of additional sources of fire blight resistance in the future.
Molecular map for Malus sieversii GMAL4593 mapping population is being developed. Fire blight resistance of population will be determined and used with the molecular map to identify a new genetic locus (QTL) conditioning resistance to fire blight in apple. New plantings of 192 M. sieversii accessions will be established in two distinct environments (Washington and West Virginia) in collaboration with Dr. Kate Evans, Washington State University, for future identification of new sources of fire blight resistance.
