A Method of QTL Mapping Based on Trait-Marker Multivariate Regression

Wen YongXian (College of Computer and Information Science,Fujian Agricultural University, Fuzhou 350002)  
Based on trait-marker multivariate regression, the method of quantitative trait loci (QTLs) mapping in each chromosome is proposed. A 'pseudo-likelihood ratio' statistic is used for significance test. Moreover, the detected QTLs are selected by the multivariate linear stepwise regression. This method is not only simplifying calculation, but also significantly increasing statistical power. A simulated example is given to elucidate this method effectively.
