Breeding efforts for increasing biofuel capability in this genus have focused on two species, namely M. sinensis (Msi) and M. sacchariflorus (Msa). For these efforts to succeed, it is critical that both Msi and Msa, as well as their interspecific crosses, are grown at higher latitudes. Therefore, the purpose of this study was to investigate how well existing data from Msi and Msa trials grown at locations throughout the northern hemisphere can train state-of-the-art genomic selection (GS) models to predict genomic estimated breeding values (GEBVs) of dry yield for untested Msi and Msa accessions in untested environments. We found that accounting for genotype-by-environment interaction in the GS model did not notably improve predictive ability. Additionally, we observed that locations with lower latitudes showed higher predictive ability relative to locations with higher latitudes. These results suggest that it is crucial to increase trial locations at higher-latitude locations to investigate the source of this correlation. This will make it possible to train GS models using data from environments that are similar to growing conditions at the locations targeted by Msi and Msa breeders. Such an increase of trial locations in target environments could pave the way towards advancing breeding efforts for overwintering ability in Msi and Msa, and ultimately support the potential of Miscanthus as a biofuel crop."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Genotype by environment model predictive ability in miscanthus"]}]}],"canonical_facts":{"dc:contributor":["Lipka, Alexander E","Jarquin, Diego","Sacks, Erik","Rutkoski, Jessica","Jamann, Tiffany M"],"dc:creator":["Widener, Sarah J."],"dc:date":["2023-05","2023-05-05"],"dc:description":["Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-05-01","The student, Sarah Widener, accepted the attached license on 2023-05-03 at 12:22.","The student, Sarah Widener, submitted this Thesis for approval on 2023-05-03 at 13:38.","This Thesis was approved for publication on 2023-05-05 at 10:47.","DSpace SAF Submission Ingestion Package generated from Vireo submission #19317 on 2023-09-01 at 17:15:55","Miscanthus is a genus of perennial grasses native to East Asia that shows promise as a biofuel energy source.
