Table 1.
Heterozygosity and inbreeding for 34 P. pinaster populations evaluated in four common gardens with contrasting environments (Asturias, Portugal, Madrid and Cáceres; figure 1). Numbers in brackets after population names denote population location in figure 1. N, number of individuals (genotypes); Ho, observed heterozygosity based on 6100 SNPs; g2, a multilocus estimator of ID; s(g2), inbreeding coefficient for the population estimated from marker data [42]; s(g2) values were not computed for the three populations with fewer than five genotypes.
