Improving the efficiency of multi-location field trials with complete and incomplete relationship information

Abstract The increasingly cost-efficient availability of ‘omics’ data has led to the development a rich framework for predicting performance non-phenotyped selection candidates in recent years. improvement phenotypic analyses by using pedigree and/or genomic relationship however received much less attention, albeit it shown large potential increasing efficiency early generation yield trials some breeding programs. aim this study was accordingly assess possibility enhance multi-location field with complete information as well when merely incomplete is available set candidates. For his purpose, four winter bread wheat trial series conducted Eastern and Western Europe were used determine experimental accuracy different resource allocations varying degree information. results showed that modelling between up 20% more efficient than employing routine analyses, where genotypes are assumed be unrelated. observed decrease reducing testing capacities furthermore pronounced information, even cases partial analyses. Exploiting both preliminary thus optimize increase gain programs make use various predictive methods.
