  1. *Admixture analysis-based ancestry estimates show there were 11 major varieties as well as hybrids derived from these varieties. We grouped these as (i) those that have at least 50 % ancestry from each of the major 11 groups and (ii) those that have multiple ancestries with none meeting the 50 % threshold
  2. **For the admixed clones (i.e. hybrids), the numbers designate the totality of the accessions that have at least 50 % of their ancestries coming from a specific genotype
  3. ***Because of the multiplicity of names associated with each unique landrace, we only attempt to provide most common ones where applicable
