Wheat Breeding Technology Workshop

Wheat Breeding Technology Workshop

The Wheat Breeding Technology Workshop was held in Sydney, Australia in September 2015, following the 2015 BGRI Technical Workshop. The proceedings were recorded and made publicly available for early career breeders and geneticists. The objectives of this video series are to impart participants with the background knowledge and practical skills required to implement crop modelling, high-throughput phenotyping, genomic selection, and speed breeding in an applied breeding program, and enable participants to think critically and collaboratively to develop improved breeding strategies for wheat that take advantages of these technologies. The production of these videos was made possible by the Borlaug Global Rust Initiative, with videography and editing by Christopher H. Knight.
