Genome anchored QTLs for biomass productivity in hybrid Populus grown under contrasting environments.

Traits related to biomass production were analyzed for the presence of quantitative trait loci (QTLs) in a Populus trichocarpa × P. deltoides F(2) population. A genetic linkage map composed of 841 SSR, AFLP, and RAPD markers and phenotypic data from 310 progeny were used to identify genomic regions...
