Introduction

In the realm of genetics and genomics, understanding the complex interactions between genes and their effects on traits is crucial for advancing our knowledge of heredity and developing new breeding strategies. One of the key tools in this endeavor is Quantitative Trait Loci (QTL) mapping, which helps identify the genetic factors contributing to a particular trait. QTLNetwork is a user-friendly computer software designed to facilitate QTL mapping in various populations, including those with epistatic effects and QE interaction effects. In this article, we will delve into the features and capabilities of QTLNetwork, exploring its potential applications and benefits in the field of genetics and genomics.

What is QTLNetwork?

QTLNetwork is a powerful software tool specifically designed for mapping QTL with epistatic effects and QE interaction effects in different types of populations. These populations include:

DH (Double Haploid): A type of population where each individual is homozygous for a specific set of genes.
RI (Recombinant Inbred): A type of population where each individual is a recombinant inbred line, created by crossing two parental lines.
BC (Backcross): A type of population where each individual is a backcross between a parental line and a recombinant inbred line.
F2 (F2 Generation): A type of population where each individual is a cross between two F1 individuals.
IF2 (Inbred F2): A type of population where each individual is an inbred F2 line.
BxFy (Backcross Fy): A type of population where each individual is a backcross between a parental line and an Fy line.
