Discovery and application of DNA markers for resistance to Teratosphaeria in E. globulus (PNC363-1415)

1st March 2017

This study used newly developed genome sequencing techniques to find trees in large populations of E. globulus that have genetic differences (i.e. alleles) that give them resistance to Teratosphaeria leaf disease (TLD). 

The process, Marker-assisted selection (MAS), will accelerate breeding programs by allowing breeders to screen large numbers of trees to identify better parental genotypes for crossing and superior genotypes arising from crosses.

The study found a number of genetic markers associated alleles that confer TLD resistance. Markers identified in this study can be combined with markers developed for other commercial traits such as wood quality and growth to select tree lines that contain favourable alleles for other traits.
