Phenotypic and genetic characterization of sixteen grain and dual-type industrial hemp varieties (Cannabis sativa L.) for agronomic and yield component traits
Front Plant Sci. 2025 Oct 20.
“Conclusion
We observed significant variation across major traits such as plant height, stem diameter, biomass, grain yield, and seed composition.
Over three consecutive years, the variety Future 83 exhibited high biomass and grain yield, suggesting stable performance.
Furthermore we observed seed shattering as a one of a major factor negatively impacting grain yield.
Our study provided preliminary insight into the molecular basis of flowering and seed development.
By comparing homologs of the soybean Pod dehiscence 1 (GmPdh1) and Terminal flower 1b ( GmTFL1b or Dt1 ) genes in industrial hemp, we explored a novel aspect of hemp genetics. Further research should explore the molecular functions of these genes for validation.
Additionally, future efforts should focus on producing hemp varieties with uniform growth and maturation, higher grain yield, and improved seed composition. This could be achieved by investigating the gene-environment interactions (G×E) to assess their adaptive suitability across the diverse agroecological zones of the Midwest.
Overall, our findings will contribute to hemp breeding and crop improvement and support hemp farmers by enhancing cultivation practices.”
