Table 1.
Strain information of 23 strains and preassigned clusters by DAPC.
Fig 1.
DAPC for 23 cannabis genotypes.
(a) The x-axis is the number of clusters k and the y-axis is the corresponding value of BIC. (b) The plot of DAPC cross-validation. The x-axis is the number of PCA axes retained for DAPC, and the y-axis is the proportion of successful outcome prediction. Individual replicates appear as points, and the density of those points in different regions of the plot is displayed in blue. (c) DAPC plot for 23 cannabis genotypes along two linear discriminants (LD 1 and LD 2).
