CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. 199(f) to Canadian Plant Breeders’ Rights Application Number 19-9707, which was filed for the instant plant variety on Jan. 18, 2019.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Cannabis (Cannabis sativa) cultivar designated as ‘MR2018001’.

‘MR2018001’ is a selection resulting from a controlled-cross between the female Cannabis sativa variety ‘Afghani Hawaiian’ (unpatented) and the male Cannabis sativa variety ‘Jamaican Landrace’ (unpatented). The plants were grown at an indoor Cannabis facility in Markham, Ontario, Canada. The plants were flowered under standard indoor environment conditions with High Pressure Sodium lamps.

Seeds from the cross were sown in Markham, Ontario, Canada and plants were screened for a number of traits including tetrahydrocannabinol (THC) and cannabidiol (CBD) levels, yield, flowering time, disease resistance and flower morphology. An individual plant having about 9% THC and about 9% CBD by dry weight and exhibiting resistance to microbial growth was chosen to be ‘MR2018001’.

In February 2016, ‘MR2018001’ was first asexually propagated by apical stem cuttings approximately 10 cm long and having multiple auxiliary meristems, in Markham, Ontario, Canada. ‘MR2018001’ is stable and reproduces true to type in successive generations of asexual reproduction. This cultivar has increased resistance to microbial growth and higher flower yield for enhanced cultivation and production of flower yield and extracts thereof.

BRIEF SUMMARY OF THE INVENTION

This invention relates to a new and distinctive Cannabis cultivar designated as ‘MR2018001’.

‘MR2018001’ exhibits about 9% THC and about 9% CBD by dry weight. ‘MR2018001’ also exhibits resistance to microbial growth.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs depict characteristics of ‘MR2018001’. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows multiple, whole plant clones of ‘MR2018001’.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar ‘MR2018001’.

‘MR2018001’ has not been tested under all possible environmental conditions. Phenotypic differences may be observed with variations in environment without any variance in genotype.

The traits of ‘MR2018001’ have been repeatedly observed and represent the distinguishing characteristics of ‘MR2018001’.

The data that follows was collected in Markham, Ontario Canada.

Plants were flowered under standard indoor environmental conditions with High Pressure Sodium lamps. Clones were cut from healthy mothers and allowed to root for 14 to 18 days prior to being introduced to the flower room. The room was maintained at 18 hour days/6 hour nights for a week to allow the cuttings to establish adequate vegetative tissue. The floral transition was initiated by switching to 12 hour days and 12 hour nights. Flowering lasted 8-9 weeks before harvest, at which point samples were taken for chemical analysis, and yield was quantified. Morphological measurements were taken from plants aged 9 weeks post-floral transition.

Standard in-house developed nutrients were used throughout growth, and the plants were defoliated and pruned as necessary throughout the cycle.

                      COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

                      ‘MR2018001’ may be compared with its parental lines with respect to THC and CBD content. Using Waters LC-MS/MS, running an Acetonitrile:Methanol:2-propanol gradient mobile phase through a Raptor ACR-18, 2.7 um, 2.1×150 mm column to quantify THC and CBD, ‘MR2018001’ exhibits about 9% THC by dry weight, the female parent exhibits 20% THC by dry weight and the male parent exhibits 2% THC by dry weight. In addition, ‘MR2018001’ exhibits about 9% CBD by dry weight, the female parent exhibits 0% CBD by dry weight and the male parent exhibits 4% CBD by dry weight.

                      A close variety of Cannabis known to the inventors is the commercial variety ‘Girl Scout Cookies’. Variety ‘MR2018001’ can be distinguished from the variety ‘Girl Scout Cookies’ by its increased resistance to microbial growth, as shown in Table 2.

                      Variety ‘MR2018001’ can also be distinguished from the variety ‘Girl Scout Cookies’ with respect to the morphological traits listed in Table 3. In particular, ‘MR2018001’ is a tall cultivar with short intranodes. As a result, the number of flowers produced on each plant is high, which translates to a high yield of dry flower per plant.

                      Markham, Ont. convenience store was selling cannabis edibles to underage teens, police allege

                      York Regional Police issued a warning after more than $10,000 worth of cannabis products were seized from a Markham convenience store.

                      The bust comes days after a three-year-old girl was rushed to hospital in Belleville and then later on to a Kingston hospital after eating marijuana edibles that looked like candy.

                      Marijuana edibles are now legal in Canada, but you have to be over the age of 19 to use them and they have to be sold through a licensed cannabis retailer.

                      York Regional Police have charged two people working at the convenience store after a concerned citizen alleged they were selling edibles that looked like candy to underage teens.

                      Police say the manager and an employee of Angus Glen Convenience on Kennedy Road were charged with possessing cannabis for the purpose of selling under the Cannabis Act.

                      They confiscated $10,000 worth of cannabis products, including cannabis vape pens, cannabis seeds and, most concerning, cannabis edibles that looked like popular candy products.

                      Investigators said the store was not registered to sell marijuana products and the products were not adequately labeled and dosage amounts were unclear.

                      “The packaging is so shocking similar to candy there could easily be someone who ingests this as a mistake," Const. Laura Nicollesaid.

                      The charges come just days after a three-year-old girl from Quite West in the Belleville area was hospitalized after ingesting cannabis edibles that were in her home.

                      OPP Media Relations Constable Devin Leeworthy said that someone called 911 after the child ate marijuana edibles from a package that looks like the popular candy Skittles.

                      Police say it’s from an illicit source not approved by Health Canada.

                      “The edibles that the child consumed were 20 milligrams each and there were 400 milligrams in that package. We were under the impression the child ate most of that package," Leeworth sai.

                      After three days the child was released from hospital. The girl’s 38-year-old father has been charged with criminal negligence causing bodily harm.

                      York investigators say if someone sees an illegal product being sold they should contact police.

                      “If you see something that is safety concern or unlawful we do ask you to come forward to report that,” said Nicolle. "It is shocking how similar the packaging is to look like legitimate candy products that are marketed and sold to children."

                      CTV News reached out to MARS, the makers of Skittles and it said it has nothing to do with cannabis, has not authorized it’s trademark to be used with illegal products and vowed to work with police.

                      Police also caution anyone with cannabis in their home to make sure it’s safely stored away from children.
