Genotype by environment interactions under commercial scenarios on performance of black tiger prawn genotypes (University of Sydney & James Cook University)


This project aims to understand the influence of genotype by environment (GxE) interactions on realizing the genetic potential of the black tiger prawn to guide the design of both traditional and genome-informed breeding programs. The project will require phenotype and pedigree data to be generated for prawns reared in commercial ponds to determine GxE influences on production traits and how these might be selected for in future breeding programs. To accomplish this, SNP-based pedigree data generated for individuals and/or pools of individuals from ponds will be analysed against as many traits as can be measured.
