Abstract Background Cannabis is an important industrial crop species whose fibre, seeds, flowers and leaves are widely used by humans. The study of cannabinoids extracted from plants has been popular research topic in recent years. China one the origins cannabis few countries with wild plants. However, genetic structure Chinese degree adaptive selection remain unclear. Results main morphological characteristics were assessed. Based on whole-genome resequencing SNPs, could be divided into five groups terms geographical source ecotype: accessions growing northwestern region; northeastern cultivated grown for fibre seed region, southwestern region. We further identified genes related to flowering time, germination, size, embryogenesis, growth, stress responses selected during process domestication. expression flowering-related under long-day (LD) short-day (SD) conditions showed that adapted different photoperiods through regulation Flowering locus T-like ( FT-like ) expression. Conclusion This clarifies offers valuable genomic resources breeding.
