Fig. 3From: The characterization of key physiological traits of medicinal cannabis (Cannabis sativa L.) as a tool for precision breedingPrinciple component analysis (PCA) for 121 cannabis lines. A Demonstrates the relationship between 13 physiological traits. Colours indicate plants vernacular classification according to strain groups association (for example, “Purple Kush” or “LA Confidential” strains). Genotypes marked in red (or a variation of red colours) reflect strains with blended THC/CBD ratio while all other colour classify genotypes containing THC and no CBD (cannabinoids profile was estimated by DNA markers). B Shows the associations between growth parameters, DTM and BDW. C Presents the relationship between traits with high breeding values (DTM, HI, BDW, PH, SD)Back to article page
