Table 3. Estimates of genetic diversity for Fusarium oxysporum f. sp. niveum population from the southeastern United States.
| Populationa | No. of isolates (N) | No. of MLG (g) | Genotypic diversity (Ĝ)b | Allelic richnessc | Allelic evennessd |
|---|---|---|---|---|---|
| GA1 | 40 | 5 | 0.188 | 2.90 | 0.391 |
| GA2 | 19 | 3 | 0.194 | 3.00 | 0.475 |
| GA3 | 20 | 5 | 0.420 | 4.85 | 0.500 |

a Four populations were sampled: Berrien county, Georgia (GA1), Cook county, Georgia (GA2), Tift county, Georgia (GA3), Florida (FL).
b Ĝ is the genotypic diversity that represents the probability of two randomly selected individuals having unique multilocus genotypes (MLG), and was calculated using R package adegenet v 1.4–1 (Jombart 2008; Jombart and Ahmed 2011).
c Allelic richness measures the number of observed MLGs.
d Allelic evenness measure of distribution of genotype abundances.
