Quantitative Trait Locus (QTL) Analysis 1
This is the first of a two-part series that describes the methods and uses of QTL analysis.
QTL Analysis 1 - Objectives and Overview
Department of Soil and Crop Sciences at Colorado State University, USA
Understanding the genetic control of quantitative traits helps plant breeders improve crop yield, disease resistance, end-use quality, and other important characteristics. Quantitative trait locus (QTL) analysis is a methodology that combines DNA marker and phenotypic trait data to locate and characterize genes that influence quantitative traits. In this pair of lessons (QTL Analysis 1 and 2) we will provide an overview of the methods and uses of QTL analysis, rather than detailed explanations of this complex statistical methodology. Upon completing this lesson (QTL Analysis 1) you should be able to:
