In order to provide a reference for hybrid breeding and plant type breeding, QTL positioning analysis of some form quality traits of Pinus taeda × Pinus caribaea was conducted. A Pinus taeda × P. caribaea F₁ population consists of 113 individuals was used to construct linkage maps for both the parents based on SSR makers. The map of female parent spanned 293.9 cM and the distance between loci varied from 3.7 to 47.9 cM, with a average distance of 15.5 cM. The distance between loci varied from 6.8 to 49.8 cM with a total length of 245.5 cM and an average maker interval of 13.6 cM in the map of the male parent. Using the MapQTL4.0^?, four QTLs for form quality traits were detected, of which two QTLs were located on the chromosome LG4 of Pinus taeda. The QTLs variance explained of the four QTLs for form quality traits was 8.6% -13.6%, which could be used for specific plant type cultivation, such as branch angle control cultivation.
