IUFRO Genomics and forest tree genetics

Genomic Selection workshop

The workshop


Over the last decade, genomic selection caused a revolution in animal and plant breeding. For long-lived organisms such as forest trees, expected gains from implementation of genomic selection are high: acceleration of breeding cycle, increase of selection intensity and of accuracy of prediction of multi-trait performance, optimal use of individual variation for long-term management of genetic diversity. First proof-of-concepts on Eucalyptus and pines have been reported. The objective of this workshop is to present statistical models and tools used to predict the phenotype of complex traits from genomic data and to discuss the most recent methodological developments from crop and animal breeding which could be of high interest for genomic selection in forest tree species.

The workshop will present in a nutshell three key steps of genomic selection implementation: (1) the optimisation of the training population in which the genomic prediction equation is estimated, (2) the construction of the genomic relationship matrix that replaces the pedigree-based relationship matrix, (3) the prediction of the breeding values with the most appropriate models. For each step, a short talk will introduce theory and concepts and will be followed by demonstrations and guided exercises with computing tools (don’t forget your laptop!). A concluding talk from Zulma Vitezica will highlight recent developments which include inter- and intra-gene interaction effects in prediction.

Target audience

The workshop target audience is faculty, students, researchers and breeders familiar with basic plant breeding theory and genotypic data. There is no specific pre-requisite on genomic selection and prediction tools.
