Progress in the Sydney rock oyster breeding program is constrained by a number of factors, in particular the number of families that are produced and how they are selected and tested. This program will accelerate SRO breeding progress in three key areas; by producing more families, earlier in each production year and using new methods for family selection.
The next step was greater understanding of the genetic parameters for QX and WM disease and how these related to other traits under selection, growth and meat condition. Genetic progress could be achieved by increasing the numbers of families available for selection, improved understanding of the genetic architecture of traits and reducing the length of breeding cycles for disease resistance. NSW DPI, SOCo, genetic specialists at CSIRO and oyster researchers at Macquarie University developed a multidisciplinary research program to deliver genetic progress for the SOCo breeding program.
