GENETIC IDENTIFICATION OF PISCIRICKETTSIA SALMONIS RESISTANT SALMONIDS

摘要

The invention relates to methods of predicting resistance to Piscirickettsia salmonis infection in a salmonid, the method comprising determining in the salmonid the alleles present at one or more DNA polymorphism within a QTL, and predicting the ability of the salmonid to be resistant to Piscirickettsia salmonis infection based on the determination of the alleles, wherein the QTL is: (a) located in linkage group 21 (GenBank ID NC_034194.1) within the coho salmon genome, or in the chromosome of coho salmon that corresponds to that linkage group, when the salmonid is a coho salmon, or; (b) a QTL that is located in a linkage group that corresponds to linkage group 21 within the coho salmon genome, or in the chromosome of a salmonid that corresponds to that linkage group, when the salmonid is not a coho salmon. The invention further relates to probes and arrays useful in such method and related methods.
