Aussie scientists claim a world first with deep dive into cannabis

The scientists say their advanced DNA analysis has created the world's most complete genomic reference.

Not all cannabis varieties are the same.

Victoria is aiming to become Australia's home of cannabis production with mooted investments in Mildura, Melbourne and Shepparton.

Victoria became the first state to legalise the use of medicinal cannabis back in 2016.

In 2018-19, Agriculture Victoria scientists sequenced 50 trillion bases of DNA.

Advances in technology mean the same amount can today be done in just three weeks, which is equivalent to 60,000 cannabis genomes or 66,000 chickpea genomes.

Most other states and territories are also trying to hitch a ride to the cannabis boom with Western Australia's Little Green Pharma aboard and a rush to hemp production in the Northern Territory.

Agriculture Victoria has already developed cannabis strains for commercial production, notably for the Cann Group.

Medicinal cannabis companies are focused on oils, pills and nasal sprays which health experts say can be used to treat chronic pain, epilepsy, multiple sclerosis and cancer.

The products currently are highly regulated in Australia with patients able to access cannabis oil and other products if their doctors apply for prescriptions.

Victorian Agriculture Minister Mary-Anne Thomas said the DNA mapping of cannabis was expected to allow faster precision breeding of medical cannabis.

Laboratories in Victoria have been fitted with technology to precisely measure and quantify cannabinoids, and are being used by Victorian scientists to identify the varieties with the best medicinal properties.

It aims to improve outcomes from plant breeding programs.

During the past four years, researchers in Victoria have created new tools which made extracting genetic information from strains of medicinal cannabis from across the world possible.

This information was then able to be put into a database.

This means scientists can link millions of DNA markers with traits such as growth rate, bud size and disease resistance, and quickly and cost-effectively test plants to meet compliance and regulatory requirements.
