Artemisia stelleriana is an Asian and North American species of plants in the sunflower family.It is native to China (Heixiazi Island in Heilongjiang Province), Japan, Korea, Russian Far East (Sakhalin, Kuril Islands, Yakutia, Kamchatka Peninsula), and the Aleutian Islands in the United States.
However a proper list of such strains is not yet available so most breeders treat all short-day plants as homozygous dominant. A true autoflower is homozygous recessive [21] for the day neutral genetics. Therefore, most crosses between classical photoperiod/short-day strains and autoflowers produce few or no autoflower progeny in the F1 generation.
This is a list of plant hybrids created intentionally or by chance and exploited commercially in agriculture or horticulture. The hybridization event mechanism is documented where known, along with the authorities who described it.
Assigned in the mid-eighteenth century, cannabis and hemp describe the entire cannabis plant for all its uses. Dried preparations of the plant are also called ganja, one of the oldest and most commonly used synonyms for marijuana.

Sinsemilla cannabis is a cultivation technique, so it should not be confused with skunk, which refers to strains with a high percentage of THC, of up to 34% THC content. [6] The expression sinsemilla is practically obsolete since feminized seeds emerged in the 1990s, seeds genetically modified to only sprout females.
The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [ 3 ] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
When plants of these two chemotypes cross-pollinate, the plants in the first filial (F 1) generation have an intermediate chemotype and produce intermediate amounts of CBD and THC. Female plants of this chemotype may produce enough THC to be utilized for drug production. [56] [57] Top of Cannabis plant in vegetative growth stage
Popular strains are often hybrids of C. sativa and C. indica. The medicinal effects of cannabis are widely studied, and are active topics of research both at universities and private research firms. Many jurisdictions have laws regulating or prohibiting the cultivation, sale and/or use of medical and recreational cannabis. [citation needed]
