Abstract

Prediction of QTL genotypes and trait phenotypes using FlexQTL™: A pedigree-based analysis approach

Highlights

  • The goal of predicting unknown phenotypes is the same for established genome-wide selection approaches and for the FlexQTLTM approach, but pedigree connectivity is at the core of the analysis, and locus-specific markers are utilized

  • Every year in the University of Florida (UF) strawberry breeding program, about a hundred crosses are made in the anticipation of superior fruit quality and better resistance to diseases

  • We utilize this data to demonstrate the ability of FlexQTLTM to predict unknown Quantitative Trait Loci (QTL) genotypes and phenotypes for a moderateeffect Soluble Solids Content (SSC) locus on Linkage Group (LG) 6A

Summary

Introduction

The goal of predicting unknown phenotypes is the same for established genome-wide selection approaches and for the FlexQTLTM approach, but pedigree connectivity is at the core of the analysis, and locus-specific markers (as opposed to genome-wide markers) are utilized. A Pedigree-Based Analysis (PBA) software called FlexQTLTM has the statistical capability to predict QTL genotypes and unknown trait phenotypes.
