Table 3 Mean predictive ability of genomic selection models using tetraploid dosage (GS-TD) and diploid dosage (GS-DD) for organic matter (OM), crude protein (CP), in vitro digestibility of organic matter (IVD), leaf dry matter (LDM), regrowth capacity (RC), and percentage of leaf blade (PLB). GS-TD and GS-DD models with the highest mean predictive ability for each trait are indicated in bold. Molecular matrices containing 1,223 markers for each data set. The broad-sense heritability is

and the narrow-sense heritability is
