Hemp plant named ‘CW2A’
The present invention provides a new and distinct hemp cultivar designated as ‘CW2A’.
Latin name of genus and species: Cannabis sativa L.
Variety denomination: ‘CW2A’.
BACKGROUND OF THE INVENTIONCannabis is a genus of flowering plants that includes at least three species, Cannabis sativa, Cannabis indica, and Cannabis ruderalis as determined by plant phenotypes and secondary metabolite profiles. In practice however, Cannabis nomenclature is often used incorrectly or interchangeably.
Hemp, also known as industrial hemp, is a type of Cannabis plant grown specifically for the industrial uses of its derived products. Hemp by definition has no more than three-tenths of one percent (i.e., 0.3%) concentration of tetrahydrocannabinol (THC). THC causes psychoactive effects when consumed and is typically associated with marijuana (i.e., Cannabis with higher THC contents). Hemp extracts produced from industrial hemp, such as extracts produced from ‘CW2A’, have no such psychoactive effects due to their low THC content. Values of total CBD and total THC obtained from laboratory testing of dried mature female flowers may show variance that results from differing growing environments, sampling methodologies, and testing techniques.
The present invention relates to a new and distinct hemp (Cannabis sativa L.) cultivar designated as ‘CW2A’. Whole-plant hemp extracts from ‘CW2A’ contain an assortment of phytocannabinoids (e.g., CBD), terpenes, flavonoids and other minor but valuable hemp compounds that work synergistically to heighten effects of products produced from ‘CW2A’. This synergistic effect is sometimes referred to as the “entourage effect”. ‘CW2A’ extracts can be used to produce a variety of products, including liquid and capsule forms for oral administration, topical products, cosmetic products, infused beverages, sport products and hemp-infused pet treats.
Despite Cannabis being consumed since at least the third millennium BC, complete scientific corroboration for uses of CBD are still in their infancy. Industry reports suggest CBD is used for a variety of health and wellness purposes, including as a sleep aid, coping with daily stress, fighting anxiety, relieving pain, assisting with cognitive function and boosting immune health. Significant research is currently being conducted at a variety of laboratories on the use of CBD as it relates to epilepsy, Post-Traumatic Stress Disorder (PTSD), cancer, autism, neuroprotection, anti-inflammatory effects, anti-tumor effects and anti-psychotic effects.
‘CW2A’ is a selection resulting from controlled-crosses using hemp germplasm from different regions of the United States. The primary goal of the breeding program was to develop a new hemp variety with high cannabidiolic acid (CBDA) concentrations and low tetrahydrocannabinolic acid (THCA) concentrations in its mature female flowers. Of the females tracing back to the original cross, the healthiest and most vigorous individual that showed no monoecious tendencies without stress manipulation was chosen to be ‘CW2A’.
The new cultivar of ‘CW2A’ was asexually reproduced via stem cuttings from vegetative and/or flowering plants, and cloning by the inventor at the inventor's greenhouses, nurseries, fields and/or facilities in Colorado Springs, Colo. and Wray, Colo. Asexual clones from the original source have been tested in greenhouses, nurseries, and/or fields. The properties of each clone from this cultivar were found to be transmissible by such asexual reproduction. The cultivar is stable and reproduces true to type in successive generations of asexual reproduction (i.e., clones from ‘CW2A’ are uniform).
BRIEF SUMMARY OF THE INVENTIONThis invention relates to a new and distinctive hemp cultivar designated as ‘CW2A’.
As used herein, the term “cultivar” is used interchangeably with “variety”, “strain”, and/or “clone”.
The inventor reproduced progenies asexually by stem cutting from vegetative and/or flowering plants, and cloning. The plant has been and continues to be asexually reproduced by stem cutting from vegetative and/or flowering plants, and cloning at the inventor's greenhouses, nurseries, fields and/or facilities in Colorado Springs, Colo. and Wray, Colo.
The accompanying color photographs depict characteristics of the new ‘CW2A’ plants as nearly true as possible to make color reproductions. The overall appearance of the ‘CW2A’ plants in the photographs is shown in colors that may differ slightly from the color values described in the detailed botanical description.
‘CW2A’ has not been observed under all possible environmental conditions, and the phenotype may vary significantly with variations in environment. The following observations, measurements, and comparisons describe this plant as grown at Wray, Colo., when grown in the greenhouse, nursery or field, unless otherwise noted.
Plants for the botanical measurements in the present application are annual plants. In the following description, the color determination is in accordance with The Royal Horticultural Society Colour Chart, Sixth Edition (2015), except where general color terms of ordinary dictionary significance are used.
‘CW2A’ is a fertile hybrid derived from a controlled-cross between proprietary cultivar ‘1AC’ as the female parent (i.e., pollen accepter) and another hemp plant as the male parent (i.e., pollen donor) originating from a feral hemp (a.k.a. ditch weed) population in Colorado with an unknown cannabinoid content (“Feral Male Parent”).
Breeding History of the Female Parent. The lineage of proprietary female parent ‘1AC’ comprises four generational crossings. The first crossing was made between a parental female from a cutting of Cannabis sativa L. originating in Colorado of unknown parentage (“First Female F0”) with a parental male plant (“First Male F0”) which originated from a feral hemp population in Colorado with an unknown cannabinoid content. Of the resulting progeny, 40 seeds were germinated and developed into 24 female (“F1 Females”) and 16 male (“F1 Males”) plants.
For the second crossing, an egg donor from a female clone of Cannabis sativa L. with unknown genealogy (“Second Female”) was crossed to a healthy vigorous F1 Male from the first cross. Of the resulting offspring, twenty seeds were germinated of which 70% were female (“F2 Females”) and 30% were male (“F2 Males”).
For the third crossing, a single F2 Female was chosen and crossed with a sibling of First Male F0. Of the resulting progeny, fifty seeds were germinated. Twenty-five seedlings were female (“F3 Females”) and 25 were male (“F3 Males”).
The fourth generation was produced by crossing two F3 Females that displayed the most vigor and health. Both F3 Females chosen for the cross were short and squat in stature, had medium to broad leaf structure with tight internodes of about ½ inch, and displayed a 70-75 day flowering maturity after flowering initiated. The F3 Female was chosen as the egg donor (“F3-e”) for the fourth generation. The F3 female was also chosen as the pollen donor (“F3-p”) for the fourth generation. The F3-p female was induced to produce male flowers, thus generating pollen, using heat and erratic photoperiod stress techniques. F3-e was pollinated by F3-p and generated progeny (F4) that were all female with slightly different characteristics. All F4 plants exhibited indica-dominant traits such as medium to broad leaf structure, short squat overall growth habit, and tight internodes with full flower maturity taking roughly 65-70 days after flowering initiated. About 90% of all F4 plants exhibited resistance to pests and diseases and showed great health and vigor throughout the entire lifecycle. Few plants displayed white and/or yellow coloration similar to marbling on the leaves. Of these F4 females, the healthiest and most vigorous individual was chosen to be ‘1AC’.
Breeding History of the Male Parent. The Feral Male Parent of ‘CW2A’ was the most vigorous and healthy male with broad, palmately compound leaves and squat stature at maturity (“indica-dominant”) which germinated from a feral hemp population. Ten seeds of the resulting offspring were germinated. Of the ten seeds, six were male and four were female. Ninety percent of all individuals exhibited resistance to pests and diseases and showed great health and vigor throughout the entire lifecycle. Nearly all of the males grew taller than the females and exhibited medium to broad leaf structure similar to indicia/sativa hybrid characteristics. The Feral Male Parent is not a genetically modified organism.
Crossing of Parental Lines. ‘1AC’ was crossed to the Feral Male Parent and all of the resulting females displayed long and slender leaflets, leaves, and overall growth pattern (“sativa-dominant”). Of the females, 75% exhibited monecious characteristics without stress manipulation. All females showed premature flowering without a change in light duration; although change in light duration to 12 hours of light and 12 hours of dark within a 24-hour period induced all females into a distinct flowering cycle. Of these females, the healthiest and most vigorous individual, that showed no monecious tendencies without stress manipulation was chosen to be ‘CW2A’.
As used herein, the term “maturity”, “harvest maturity,” or “floral maturity” refers to the developmental stage at which the ‘CW2A’ plant is harvested. Persons having skill in the art will recognize maturity based on the plant's morphologies. It is also good practice to conduct periodic cannabinoid content (i.e., potency) tests throughout the development of the plant to ensure that harvest occurs at maturity. The ‘CW2A’ plant is considered to be at harvest maturity when fan leaves begin to yellow, and when inflorescences begin to take on a ‘frosted’ appearance, as trichomes develop on calyxes and lower portions of bracts. If bracts and inflorescent parts turn overly yellow and/or if the ‘frosted’ appearance is visible from afar, this could indicate the plant is beyond maturity. The color of trichomes can also be used to determine maturity. Trichomes from the ‘CW2A’ plant first look small and clear, but gradually enlarge, and progressively become ‘milkier’ and opaque with continued maturation, finally displaying a desiccated appearance and amber color. In the present disclosure, harvest maturity is defined as the time period between the enlarged clear trichome developmental stage and the opaque/milky trichome developmental stage. Amber trichomes in the ‘CW2A’ plant are an indication of overly mature trichomes. In some embodiments, the harvest maturity of the ‘CW2A’ variety is typically around 15 and ½ weeks after planting vegetative cuttings in the field. Growing conditions throughout the plant's life cycle, nutrient variations, and environmental factors can all influence the amount of time for ‘CW2A’ plants to reach harvest maturity. The present disclosure uses the terms “maturity,” “harvest maturity,” and “floral maturity” interchangeably.
In some instances, the botanical descriptions disclosed herein reflect the range of phenotypical variation observed under indoor and outdoor growth conditions. Total Potential THC/CBD contents presented in this document reflect the total potential (i.e., decarboxylated) THC and CBD content after decarboxylation of the THCA and CBDA contents of the sample. The formula used for this calculation is reproduced below for the Office's convenience. Total THC=THC+(THCA*(0.877)). Total CBD=CBD+(CBDA*(0.877)).
When ‘CW2A’ is compared to the feral male parent (a.k.a. ditch weed), ‘CW2A’ is taller in plant height, but narrower in plant width than the feral male parent. The indica-dominant feral male parent having a squat statute are shorter than ‘CW2A’ and branch wider with wider leaves than ‘CW2A’.
When ‘CW2A’ is compared to the proprietary female parent (‘1AC’), ‘CW2A’ is taller in plant height, but narrower in plant width than ‘1AC’. Generally, ‘CW2A’ is twice as tall as it is wide, while ‘1AC’ has a similar ratio of plant height to width. ‘CW2A’ with 19-29 teeth of middle leaflet has narrower leaflets than ‘1AC’ with 26-37 teeth of middle leaflet. Regarding petiole length at maturity, ‘CW2A’ is in general shorter than ‘1AC’. Regarding stem diameter at base, ‘CW2A’ is in general shorter than ‘1AC’. When comparing individual flower length and compound cyme diameter, ‘CW2A’ is smaller in size than ‘1AC’. On the other hand, ‘CW2A’ has generally a longer and thinner stigma than ‘1AC’. While ‘1AC’ does not show hermaphroditic tendency, hermaphroditic plants are observed from ‘CW2A’ depending on growth conditions. Since ‘CW2A’ branches are highly flexible, ‘CW2A’ plants lean over more than ‘1AC’ that has less flexible branches. With regard to time to harvest seeds, ‘CW2A’ shows a shorter harvest time than ‘1AC’. After stem cutting from vegetative and/or flowering plants, adventitious roots of ‘CW2A’ emerge and grow faster than ‘1AC’.
When ‘CW2A’ is compared to the known Cannabis plant named ‘ECUADORIAN SATIVA’ (U.S. Plant Pat. No. 27,475), there are several distinctive characteristics. For example, ‘CW2A’ plant is generally taller than the ‘ECUADORIAN SATIVA’ plant. While the aroma of ‘ECUADORIAN SATIVA’ is strongly mephitic with hints of limonene, ‘CW2A’ has an earthy aromatic herbal smell with a hint of citrus and/or pine scent and a general sweetness. ‘CW2A’ stem diameter at base is greater than ‘ECUADORIAN SATIVA’. Also, individual pistillate flowers and stigma of ‘CW2A’ are longer than those of ‘ECUADORIAN SATIVA’. Furthermore, there is a significant difference in total THC content between ‘CW2A’ and ‘ECUADORIAN SATIVA’. The total THC content of ‘CW2A’ is between 0.13-0.27%, rendering the claimed plant a hemp plant under U.S. law. ‘ECUADORIAN SATIVA’ on the other hand, accumulates 12.45% total THC, resulting in a different classification of the plant.

In addition, provided herein are further descriptions of the new cultivar of ‘CW2A’ CW2A has the following characteristics:
Growth Habit:
-
- CW2A plant has long and slender leaflets/leaves and is 1-4 meters in height at maturity depending on growth conditions (“sativa-dominant”). Monoecious characteristics without stress manipulation are not common, but occasionally observed. Dioecious plant has hermaphroditic tendencies.
- CW2A also shows premature flowering without change in light duration though it is still responsive to light/dark cycle (12/12 hours) for inducing flowering. Elongated nodes bear palmately compound leaf structures on elongated petioles. Nodes tend to stack in early growth stages and elongate in later parts of vegetative growth. In immature vegetative growth stages, the plant often shows flower primordia or fully formed flower structures as evidenced by pairs of white, hair-like stigmatic tendrils at nodal branch points. Inflorescences are long and spear like indeterminate inflorescences.
Flowering and Seed Formation:
Timing of flowering is largely dependent (if not entirely) on photoperiod.
Week 1-Week 2
-
- vigorous growth,
- pistillate flowers are already present, the maturity rate and pistillate flowers grow very rapidly and multiply,
- pistillate flowers are in prime condition for pollination and beginning seed formation in early flowering stages due to monecious characteristics.
Week 2-Week 4 - vigorous growth continues,
- more pistillate flowers grow and begin forming first bud like structure between two and three weeks,
- pistillate flowers are in prime condition for seed formation up to three and a half weeks.
Week 4-Week 6 - vigorous growth slows down,
- buds begin to swell,
- plant has nearly doubled in size from last day of vegetative stage,
- bud characteristics begin to mature,
- plant terpenes are at their peak potency at 6 weeks,
- male staminate flowers begin to form and open (yellow banana shaped sacs).
Week 6-Week 8 - buds begin to swell to full potential,
- seeds begin to form and mature at internodes and within flower buds,
- all characteristics are realized,
- yellowing of the leaves occur naturally,
- cannabidiol compounds are at their peak at week 8,
- leaves begin to naturally yellow.
Week 8-Week 10 - leaves dry,
- leaves and seeds drop,
- volatile terpene compounds extremely diminish,
- cannabidiol compounds slowly diminish.
Growth Conditions:
Vegetative Stage - 75-85 degrees F. is ideal, temps up to 90 degrees F. are not harmful,
- 40-60% relative humidity.
Flowering Stage - 75-85 degrees F. (nights getting cooler, as low as 40 degrees F.),
- 40-50% relative humidity.
In another embodiment, temperature and humidity ranges may be decreased or increased to account for all weather conditions.
Shape of Plant at Maturity:
-
- long and spear like flowers,
- bushy but elongated branches,
- height and shape depends on planting pattern,
- when planted with space (5 feet apart), plant bushes and is 5-6 feet tall,
- when planted close (2 feet or less apart), plant is longer and more string/spear flower characteristics and be up to 12 feet tall.
Branching Habits: - dependent upon planting pattern. With sufficient space, the plant forms branches 360 degrees with a concentration of branches forming toward the sun or light source. The branches are long, spear like, and have tendency to break in high winds due to its length (flower and leaf surface area). Node length on branches start very short in early vegetative stage and elongate as the plant matures. Full flower internode length can be up to 3″ inches long.
Rooting Ability: - Roots grow easily under the proper environment starting from propagation that comprises a temperature of about 70-75 degrees Fahrenheit, 50% relative humidity, 35-55% moisture content in the soil or media, and appropriate lighting.
- Feeder roots grow 360 degrees, are typically found 3″ inches below ground level, and stay in the top 18″ inches of soil. Brace roots typically stay within the center of the plant and can go as deep as 3 feet for maximum stability in windy conditions.
Timing of Duration of Flowering Session:
The timing of the flowering duration is dependent on the degrees latitude positioned on the globe. The dates are dependent on the northern or southern hemisphere. Northern Hemisphere is used below:
-
- 40-50 degrees latitude typically begins flowering stage July 5-July 15 to full maturity September 10-September 20; 30-40 degrees latitude typically begins flowering stage July 15- July 25 to full maturity September 20-September 30; 15-30 degrees latitude a later and longer flowering duration is assumed; 0-15 degrees latitude flowering will occur any time of the year because of consistent 12-13 hours of sunlight/day.
In another embodiment, temperature and time ranges may be decreased or increased to account for location change.
