Comparison of the number of years in the training populations on overall GS model accuracy and pairwise comparisons for stripe rust infection type (IT) and disease severity (SEV) for PNW winter wheat over both the DP lines and BLs phenotyped from 2013 to 2020 in Central Ferry, Lind, and Pullman, WA, USA in the cross-validation sets.

Trait	Year 1	Year 2	Year 3	Year 4	Year 1–2	Year 1–3	Year 1–4
IT	0.52d	0.43f	0.57a	0.54c	0.49e	0.56b	0.57a
SEV	0.53f	0.55e	0.61b	0.59c	0.58d	0.62a	0.63a

Models labeled with the same letter are not significantly different (P-value = 0.05).
