Biomass yield is strongly influenced by genotype\u2010by\u2010environment (G \u00d7 E) interaction. We evaluated genomic prediction models for biomass yield, spring emergence (SE), and flowering time (FT) in half\u2010sibs at three southeastern US locations (Watkinsville, GA; Tifton, GA; and Knoxville, TN). Predictive performance was assessed within each site\u2010year using five\u2010fold cross\u2010validation, comparing a parental general combining ability (GCA) baseline with Bayesian models, genomic BLUP (GBLUP), and a dominance model (GBLUPD). We further quantified the sensitivity of yield prediction to single\u2010nucleotide polymorphism (SNP) density. Predictive abilities as Pearson\u00a0correlation coefficient (PCC) increased as the SNP number rose from the minimum of 100 to 2500\u20135000 SNPs, with only minimal gains observed up to 10,000 SNPs and beyond. Genomic models consistently outperformed parental GCA baseline for yield, with the highest PCC of 0.45\u20130.55 in 2022 for Georgia, followed by declines (PCC\u00a0=\u00a00.25\u20130.35) in 2024. This indicated stronger G \u00d7 E (where E represents combined year\u2010location) impacts on mature switchgrass stands. FT showed higher predictive ability than yield, with PCC\u00a0&gt;\u00a00.50 in Georgia and PCC\u00a0&gt;\u00a00.28\u20130.33 in Tennessee. SE exhibited intermediate\u2010to\u2010high PCC of 0.65\u20130.70 in Georgia during 2022\u20132023 and a PCC of 0.45\u20130.47 in Tennessee. The GBLUPD provided small repeatable gains for yield and SE in comparison to GBLUP. FT exhibited genetic correlations exceeding 0.90 at Knoxville, which showed it as a transferable predictor for multi\u2010environment selection. Collectively, these results indicate that modest SNP sets can be sufficient for yield prediction and highlight environment\u2010dependent model performance.\n
