The content of CBDA and CBD was determined in three hemp genotypes, sown in two different seasons. Six experimental variants resulted, V1 (Silvana, S1), V2 (Silvana, S2), V3 (Loja, S1), V4 (Loja, S2), V5 (Finola, S1), and V6 (Finola, S2). The CBDA content varied between CBDA = 0.43±0.04% (V4) and CBDA = 0.70±0.04% (V5). The CBD content varied between CBD = 0.52±0.06% (V1) and CBD = 0.88±0.06% (V2). The CBDA/CBD ratio varied between CBDA/CBD = 0.5774±0.0688 (V2) and CBDA/CBD = 1.0577±0.0688 (V2). The CBD/CBDA ratio varied between CBD/CBDA = 0.0455±0.1115 (V1) and CBD/CBDA = 1.7320±0.1115 (V2). Compared to the mean value of the experiment, in the case of the CBDA, variant V5 presented positive differences, and variant V4 negative differences (p<0.05). In the case of the CBD, compared to the mean of the experiment, variant V1 presented negative differences (p<0.05). Based on PCA, PC1 has explained 64.27% of variance, and PC2 has explained 35.134% of variance. Cluster grouping and a ranking of the experimental variants were generated, in relation to the considered indices.
