Table 1. Measures of within-landrace genetic diversity in seven tetraploid wheat accessions.

No. Genotypes: number of different genotypes detected in the sample; Freq. Genotypes: number of individual plants with a particular genotype within the sample; Hz: Heterozygosity; GD: Gene Diversity; PIC: polymorphism information content; M/P markers: number of polymorphic/monomorphic markers; Rare Alleles: number of rare alleles (an allele other than the most frequent one for each loci analysed) detected in the landrace (the total number of alleles detected for each landrace accession is under brackets); Hg (%): heterogeneity within varieties calculated as the number of alleles, other than the most frequent one, detected for a particular marker/landrace combination, considering the totality of alleles genotyped. e.g. for Recio, given 20 individuals analysed at 15 SSR loci, there is 1 instances of a rare allele being detected, so heterogeneity is 0.34%.
