DescriptionSingle marker regression and single marker maximum likelihood estimation were tied to detect quantitative trait loci (QTLs) controlling the early height growth of longleaf pine and slash pine using a ((longleaf pine x slash pine) x slash pine) BC, population consisting of 83 progeny. Maximum likelihood estimation was found to be more power than regression and could also estimate the distance between markers and QTLs. Test statistic for the relationship between simple regression and maximum likelihood estimation is introduced. A total of four major QTLs linked to random amplified polymorphic. DNA (R4PD) markers were detected explaining 19.7%, 10.7%, 12.8%, and 9.9% total variance of total height. Multiple regression analysis indicated that these four QTLs explained about 43.2% of the total variance of early height growth.
