Only female plants produce flowers (buds, buds). To create new genotypes, that is,. Strains, breeders need both male and female plants. Male plants are used to pollinate female plants, and the seeds of the resulting plant are grown to identify and isolate female flower producing plants.
Haze is probably the most cultivated and recognized 100% sativa hybrid in the world. Its origins date back to the early 1970s in the region of Santa Cruz, California (USA. UU.). During this time, two brothers known as Haze Brothers (R.
Haze) grew and crossed different cannabis lines using seeds of the best imported sativa strains, most often offered by their friend and neighbor Sam The Skunkman. It all started with a hybrid between a sativa native to Mexico and another native to Colombia. A year later, the best selected females of this hybrid were crossed with a native strain from southern India. Finally, the female offspring of this new hybrid were crossed again with a male native to Thailand.
All cannabis strains come from the Cannabaceae plant family. Some experts consider Cannabis indica and Cannabis sativa to be the two main subspecies, although some people think they are separate species. Cannabis strains are pure or hybrid varieties of the plant genus Cannabis, which encompasses species C. The two most frequently cultivated species of the genus Cannabis are Cannabis indica and Cannabis sativa.
A third species, Cannabis ruderalis, is very short and produces only traces of tetrahydrocannabinol (THC), so it is not commonly cultivated for industrial, recreational or medicinal use. However, because Cannabis ruderalis blooms regardless of photoperiod and age, it has been used to breed autoflowering strains. In addition to pure indica, sativa and ruderalis varieties, hybrid varieties with varying proportions of these three types are common, such as the White Widow hybrid, which has approximately 60% indica and 40% sativa ancestry. These hybrid varieties exhibit traits of both parent types.
There are also commercial cross-hybrids that contain a mixture of ruderalis, indica or sativa genes, and are usually autoflowering varieties. These strains are mainly bred for the medical cannabis market, as they are not highly appreciated by recreational cannabis users because ruderalis varieties are lower in THC and impart a slightly unpleasant taste. Lowryder was an early autoflowering hybrid that maintained the flowering behavior of ruderalis plants, while producing appreciable amounts of THC and CBD. Autoflowering cannabis strains have the advantage of being discreet due to their small stature.
They also require shorter growth periods, as well as having the added advantage that they don't rely on a change in photoperiod to determine when to bloom. But, as any consumer of recreational or medical marijuana can say, not all cannabis is created equal. Different cannabis strains produce different effects and can therefore be used for different reasons. Once a native variety moves away from its original growing environment, it must mature under new conditions.
Consequently, the plant acquires new traits and will not stabilize for generations. When that process finally takes place, you have a different strain than the original. It is now a phenotype rather than a true native race. Your favorite hybrid strain probably comes from a long line of careful artificial selection, but it all started with one or more native strains.
Strains aren't an exact science, but sativa strains are usually associated with a common set of effects. Strain names that clarify that story; whether it is the potential effects, country of origin, combined genetic background, or the producer's strong sense of humor, the name of a strain is meaningful, even if that meaning is obscured. There is also more information than ever available for free through resources such as the Weedmaps strain finder, Wikileaf and Leafly if you want to fall into an online cannabis rabbit hole. For there to be genetic stability within a marijuana strain, the breeder has to go through selection and breeding, identifying the dominant and recessive genes within the two strains that are crossed.
However, long before there were strong, fast-growing hybrid strains that are popular in today's legal recreational states, there were those known as native strains. Although strains can transmit powerful or sensitive messages, strain nomenclature can also be completely random. All of these strains are a cross of two or more varieties of marijuana, as are the vast majority of their parent strains. Today, native strains have been selectively bred and blended to create hybrid strains that have more THC, shorter growth times or a higher yield.
