Quantitative trait loci (QTL) analysis is the science of discovering genes or chromosome regions that influence the expression of quantitative traits. Statistical methods for doing this have evolved from single marker analysis of variance (ANOVA) to more complex approaches such as interval mapping and multiple QTL mapping. The goal of this project was to refine a previously identified QTL chromosome region responsible for rhizome growth in grass hybrids developed from two species of the Triticeae tribe by categorically progeny testing seven recombinant genotypes containing cross overs in a major-effect rhizome QTL. In addition, the analysis addressed physical concerns with the field plot, assessing statistical power, multiple comparison testing and linkage segregation assessment.
