  • G is the genomic relationship matrix, A is the additive pedigree relationship matrix, and H.VEG is the hyperspectral relationship matrix derived from BLUEs calculated across hyperspectral phenotyping time-points collected at the vegetative stage. Single- and multi-kernel models using relationship matrices H.HEAD, H.GF, and H.ALL follow the same form as those using H.VEG shown here.
