FIGURE 5.

Mean within-population pairwise relatedness based on Lynch and Ritland (1999) index for C. canephora genotypes belonging to two main populations plus an admixture group defined by STRUCTURE. Populations as identified by structure: The admixture group was made up of 62 samples; the first cluster comprised 58 accessions from CRIG, 28 from Togo, 18 from CNRA, and one with unknown source; the second cluster comprised all 33 accessions introduced from Vietnam, 27 accessions from CRIG, 10 from CNRA, six from Cameroon, 11 from Togo and 16 with unknown sources. The mean r value is indicated by the blue diamond shape on each bar. The number of pairs compared per group is indicated above the mean r values. The bars bound the 95% confidence interval about the null hypothesis of ‘no difference’ across the populations as determined by 9999 permutations.
