Abstract

The unique annual herbaceous Cannabis plant variety ‘Red KROSS02-BK’ is provided. The variety can be distinguished by its outstanding features as described.

Description

Latin name of the genus and species: Genus—Cannabis. Species—hybrid.
Variety denomination: The new Cannabis plant claimed is of the variety denominated ‘Red KROSS02-BK’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct annual variety of a Cannabis hybrid, which has been given the variety denomination of ‘Red KROSS02-BK’. ‘Red KROSS02-BK’ is intended for use in industrial applications, for example, as a source of fiber, pulp, biomass, seed, and seed oils that serve as raw material for textiles; paper products; construction materials; animal forage; dietary supplements; and/or cannabinoid extracts, distillates, and isolates.
SUMMARY OF THE INVENTION
The new variety was developed from plants initially produced from the open pollination of the hybrid variety ‘Ringo's Gift’ (not patented) by a hemp hybrid variety known as ‘Red Kross’ (not patented) that is the F1 offspring of the hemp hybrid varieties ‘Baox’ (not patented) and ‘Finola’ (not patented). After pollination, F1 seed was collected and subsequently planted on a 20-acre plot.
Successive, multiple family group selection was carried out in order to decrease harvest time to 80-100 days, increase stem productivity and fiber content, and decrease the content of tetrahydrocannabinol (THC) compounds while keeping cannabidiol (CBD) levels above 10%. Selection by anatomic structure of cross section of the stem and high terpene profiles in the flowering stage was also included.
100 self-pollinated F2 plants were selected based on vigor and desirable phenotypic characteristics. This initial selection was followed by a second selection of 5 plants from among the 100 plants initially selected. The 5 plants were allowed to self-pollinate, and F2 seed was collected and then grown on a 1-acre plot. Cannabinoid profiles of F2 plants were tested, and the new variety was selected as a single plant.
A phytochemical profile characterized by ultralow or undetectable levels of all cannabinoid compounds except for cannabidiolic acid (CBD-A), specifically undetectable levels of the cannabinoid compounds: cannabigerolic acid (CBG-A), cannabigerol (CBG), CBD, Δ9-tetrahydrocannabinolic acid (THC-A), Δ9-tetrahydrocannabinol (Δ9-THC), Δ8-tetrahydrocannabinoil (Δ8-THC), Δ10-tetrahydrocannabinol (Δ10-THC), cannabichromenic acid (CBC-A), cannabichromene (CBC), cannabigerovarinic (CBGV-A), cannabidivarinic acid (CBDV-A), cannabidivarin (CBDV), tetrahydrocanabivarinic acid (THCV-A), tetrahydrocannabivarin (THCV), cannabichromevarinic acid (CBCV-A), cannabinol (CBN), cannabicyclol (CBL), and cannabinodiolic acid (CBND-A); cannabidiolic acid (CBD-A) levels under 10% w/w; and total cannabinoid levels under 10% w/w.

Multiple clones of the selected plant were created. For the cloning reproduction, all clones were taken on the same day, Dec. 5, 2020. A single mother plant of the new variety produced 150 ‘Red KROSS02-BK’ clones, ensuring genetic homogeneity of experimental plants, which became second-stage mother (M2) plants. Subsequently, a total of 500 ‘Red KROSS02-BK’ clones were taken from 100 M2 plants, 5 clones from every M2 plant. Branches, 20 cm long, were initially cut from M2 plants with a pair of pruning shears and were placed in water and 5 ml of 5% hydrogen peroxide until the application of treatments described below. Cut clones were stripped of lower fan leaves using pruning shears, and then were re-cut at a 45° angle to a 15 cm length. The ends of each leaf were cut in order to promote new growth. The bottom of each clone stem was then dipped in a root stimulant and inserted in a substrate with the stem tip approximately 1.5 cm from the plug base and placed into a seedling tray. The trays were covered with 7″ humidity domes with closed vents, and were placed on their appropriate table on a Hydro farm seedling heat mat. The following characteristics of the new variety have been repeatedly observed in each of the clones and can be used to distinguish ‘Red KROSS02-BK’ as a new and distinct variety of Cannabis:
    • 1. A phytocannabinoid profile characterized by
      • a. Undetectable levels of the cannabinoid compounds cannabigerolic acid (CBG-A), cannabigerol (CBG), CBD, Δ9-tetrahydrocannabinolic acid (THC-A), Δ9-tetrahydrocannabinol (Δ9-THC), Δ8-tetrahydrocannabinoil (Δ8-THC), Δ10-tetrahydrocannabinol (Δ10-THC), cannabichromenic acid (CBC-A), cannabichromene (CBC), cannabigerovarinic (CBGV-A), cannabidivarinic acid (CBDV-A), cannabidivarin (CBDV), tetrahydrocanabivarinic acid (THCV-A), tetrahydrocannabivarin (THCV), cannabichromevarinic acid (CBCV-A), cannabinol (CBN), cannabicyclol (CBL), and cannabinodiolic acid (CBND-A);
      • b. cannabidiolic acid (CBD-A) levels under 10% w/w;
      • c. total cannabinoid levels under 10% w/w; and
    • 2. an autoflowering vs. photoperiod reproductive cycle.
Plants of the new variety differ from plants of the seed parent ‘Ringo's Gift’ and from the pollen parent ‘Red Kross’ in their phytochemical content. In particular, ‘Red KROSS02-BK’ differs from both parent strains in that it has ultralow or non-detectable levels of all cannabinoid compounds except for cannabidiolic acid (CBD-A), cannabidiolic acid (CBD-A) levels under 10% w/w, and total cannabinoid levels under 10% w/w. These differences make the new variety especially desirable for industrial uses because a phytocannabinoid profile that lacks psychoactive cannabinoids exempts the plant material and oil extracts from prohibitions imposed by the Controlled Substances Act and greatly reduces or eliminates the need to remediate extracts to remove psychoactive cannabinoids. Production costs and efficiency are thereby greatly improved, making the variety especially useful and desirable for industrial applications such as preparing CBD-A isolate.
