Principle and Methodology of QTL Analysis in Crop

Abstract

Abstract: Most agronomic traits are quantitative traits. Mapping of quantitative trait loci (QTL) is based on Morgan linked inheritance principle. QTL mapping populations include the primary mapping population, the secondary mapping population and the advanced mapping population. Methods of QTL analysis include the single marker mapping, the interval mapping, the composite interval mapping and the mixed linear model. The precise of QTL mapping are affected by the population size, analysis method, QTL distribution and so on. Some disadvantages are found in traditional mapping populations and analysis methods, so new mapping populations and new methods are need in future QTL analysis.
