In boreal forests, autumn frost tolerance in seedlings is a critical fitness component because it determines survival rates during regeneration. To understand the forces that drive local adaptation in this trait, we conducted freezing tests in a common garden setting for 54 Pinus sylvestris (Scots pine) populations (5000 seedlings) collected across Scandinavia into western Russia, and genotyped 24 of these populations (900 seedlings) at 10 000 SNPs. Variation in cold hardiness among populations, as
