Sample populations of 157 Cannabis accessions of diverse geographic origin were surveyed for allozyme variation at 17 gene loci. The frequencies of 52 alleles were subjected to principal components analysis. A scatter plot revealed two major groups of accessions. The sativa gene pool includes fiber/seed landraces from Europe, Asia Minor, and Central Asia, and ruderal populations from Eastern Europe. The indica gene pool includes fiber/seed landraces from eastern Asia, narrow-leafleted drug… 

Latitudinal Adaptation and Genetic Insights Into the Origins of Cannabis sativa L.

Molecular evidence reveals for the first time that the low latitude haplogroup (Haplogroup L) is the earliest divergent lineage, implying that Cannabis is probably originated in low latitude region.

Phylogenetic resolution of the Cannabis genus reveals extensive admixture

An initial impression of the complexity within the Cannabis genus is provided and the understanding of the genetics underlying evolutionary history and population stratification is added, which will be critical for future crop improvement for any potential human use.

A Multivariate Analysis of Allozyme Variation in 93 Cannabis Accessions from the VIR Germplasm Collection

The Vavilov Institute in Russia maintains the world's largest collection of Cannabis sativa hemp germplasm through periodic seed regeneration through periodic Seed regeneration, which shows little tendency for the accessions to cluster according to country of origin or their assignment to eco-geographical groups.

A Combined Analysis of Agronomic Traits and Allozyme Allele Frequencies for 69 Cannabis Accessions

Southern and eastern Asian hemp (fiber/seed) accessions group apart from hemp accessions from Europe, Asia Minor, and central Asia and had significantly higher levels of THC and lower levels of CBD, wider leaflets relative to their length, longer xylem fibers, and lower bast fiber content.

Assessment of Genetic Diversity and Population Structure in Iranian Cannabis Germplasm

This investigation has explored the use of Genotyping-By-Sequencing (GBS) in Iranian cannabis and found some strong signal to define some locations as population according to fineSTRUCTURE analyses, however, single nucleotide variant analysis uncovered a relatively moderate level of variation among Iranian cannabis.

Differentiation between fiber and drug types of hemp (Cannabis sativa L.) from a collection of wild and domesticated accessions

Accessions of wild and domesticated hemp (Cannabis sativa L.) originating from Colombia, Mexico, California, Bolivia, Thailand, Afghanistan, Serbia, Hungary, south Africa and different regions of

A classification of endangered high-THC cannabis (Cannabis sativa subsp. indica) domesticates and their wild relatives

The classification presented here circumscribes and names four taxa of Cannabis that represent critically endangered reservoirs of germplasm from which modern cannabinoid strains originated, and which are in urgent need of conservation.

Whole-genome resequencing of wild and cultivated cannabis reveals the genetic structure and adaptive selection of important traits

The expression of flowering-related genes under long-day and short-day conditions showed that Chinese cultivated cannabis is adapted to different photoperiods through the regulation of Flowering locus T-like ( FT-like ) expression.

Potentials and Challenges of Genomics for Breeding Cannabis Cultivars

The main advances in the genomic field of this species are resumed and a discriminant and polymorphic panel of SSR markers are provided as a valuable tool for future marker assisted breeding programs.

Comparative Genetic Structure of Cannabis sativa Including Federally Produced, Wild Collected, and Cultivated Samples

Although the sample size was small, “research grade marijuana” provided for research is genetically distinct from most retail drug-type Cannabis that patients and patrons are consuming.



Genetic diversity of Cannabis sativa germplasm based on RAPD markers

RAPD markers provide a powerful tool for the investigation of genetic variation in cultivars/accessions of hemp and Variability within the two cultivars ‘Carmagnola’ and ‘Fibranova1’ was shown, suggesting good possibilities for long–term selection work.

Patterns of diversity in Cannabis

SummaryA Cannabis germplasm collection was evaluated for traits relevant to the use of hemp as an arable source of paper pulp. The traits were related to stem yield and quality, psychoactive potency,

The genus Cannabis has had a long association with man and contains considerable variation in growth form, achene size, and chemical content. The variation has taxonomically been variously

Multivariate analysis of a sour cherry germplasm collection

Morphological traits of 16 sour cherry (Prunus cerasus L.) cultivars and of hybrid and open-pollinated seedlings of germplasm collected in eastern Europe were evaluated with principal component (PC)

Genetics of Plant Isozymes

The discovery in many populations of relatively high levels of polymorphism at isozyme loci has forced a major reconsideration of evolutionary theory.


There can be no progress in unravelling the taxonomic complexities in the genus until the biology of the wild populations is investigated, because of the extraordinary plasticity and variability of cultivated cannabis.

Cannabis sativa L. - Botanical Problems and Molecular Approaches in Forensic Investigation.

: An overview on legal regulation, taxonomy, and botanical and chemical methods of analysis of marijuana are provided. Emphases are placed on the applications of the recently developed molecular

Isozymes and the Analysis of Genetic Structure in Plant Populations

Genetic variation in plant populations is distributed nonrandomly, with marked genetic differences occurring over short distances, like the plants themselves, genes and genotypes tend to be clumped.
