  1. The 9 regions (CAM, CHS, GAPDH, GIA, GPX, GST, PGIC, SCR1 and SCR2) in common with Liu and Burke report were re-analyzed in the inbred lines (19 alleles/19 accessions), the improved and primitive cultivated accessions surveyed by Liu and Burke (32 alleles/16 accessions) [46] and the complete set of accessions pooled together (51 alleles). The diversity estimates (πT and θW) displayed the same pattern independently the loci surveyed.
  2. aNucleotide polymorphism and nucleotide diversity obtained with the complete set of 28 genes studied in Table 2.
  3. b Nucleotide polymorphism and nucleotide diversity obtained by Liu and Burke [46]
