Diversity statistics computed using 29911 Panzea SNP markers over the whole panel and five main genetic groups.

aAbb: abbreviation describing the group,
bNq = ∑i δiq with i the index of lines and q the index of groups, δiq the assignment proportion of line i to group q according to STRUCTURE software [40], [41] using 55 SSRs, Nq the number of lines in group q;
cnumber of lines assigned to group q with a genome proportion above 0.8;
dmean similarity within each group, calculated with IBS (identity by state);
eexpected heterozygosity inside each group computed with r-Hierfstat [46];
f percentage of polymorphic loci within each group,
d,e,fstatistics were computed considering lines with assignment to one group above 0.8.
