This is from David Jordan, Sorghum Breeder, Queensland Alliance for Agriculture and Food innovation at the University of Queensland, Brisbane, Australia.
I think John Gibson (Message 16) makes some excellent points which are equally relevant to plant breeding. In order for application of genomic selection methods to generate good returns there is a requirement for a large suite of supporting skills and infrastructure (high level of conventional plant breeding capacity, DNA extraction, data management systems, seed and DNA inventory and tracking systems, statistics, rapid generation turn around, perhaps double haploid systems etc). In many cases, these are hard or impossible to develop and maintain for sufficient time and the loss of a single capacity can prevent the system from functioning. Building and maintaining these systems is a big challenge in many developing countries. In addition, I think there are also major issues of scale. Genomic selection is not well suited to small scale breeding programs which are typical for plant breeding programs in many parts of the world. As a result, many programs lack the necessary scale to make use of the potential benefits such that resources used to develop the integrated suite skills and capacities for genomic selection would generate greater benefits if simply applied to improving conventional breeding capacity.
