Quantitative Trait Loci (QTLs) for Intumescence Severity in Eucalyptus globulus and Validation of QTL Detection Based on Phenotyping Using Open-Pollinated Families of a Mapping Population.

Intumescence is a nonpathogenic physiological disorder characterized by leaf blistering. This disorder can affect growth and development in glasshouses and growth chambers and may be confused with pathogenic diseases. We used quantitative trait loci (QTL) analysis to examine the genetic basis of variation in intumescence severity in Eucalyptus globulus, and test for colocation with previously detected QTLs for pathogen susceptibility.
