Abstract: Sesame (Sesamum indicum L.) is an important oil crop in Ethiopia.
Despite its importance in the country, there are constraints that need to be addressed through scientific research.
Two PCR-based molecular markers have been developed.
Shattering is the number one cause of yield loss in sesame.
The major constraints are lack of improved varieties, low yield of landrace cultivars, indeterminate flowering nature and shattering of capsules at maturity, insects, diseases, heat and drought.
Conventional sesame breeding efforts started in the late 1960s, and since then a total of 26 varieties have been developed and released.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. Primary psychoactive effects include a state of relaxation, and to a lesser degree, euphoria from its main psychoactive compound, tetrahydrocannabinol.
There are 483 identifiable chemical constituents known to exist in the cannabis plant, Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. Secondary psychoactive effects, such as a facility for philosophical thinking, introspection and metacognition have been reported among cases of anxiety and paranoia.
The number of species within the genus is disputed.At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C.The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant. ruderalis is short, branchless, and grows wild in central Asia.Male flowers are normally borne on loose panicles, and female flowers are borne on racemes. The genus Cannabis was formerly placed in the Nettle (Urticaceae) or Mulberry (Moraceae) family, and later, along with the Humulus genus (hops), in a separate family, the Hemp family (Cannabaceae sensu stricto). In the United States alone, it is believed that over 100 million Americans have tried cannabis, with 25 million Americans having used it within the past year.Recent phylogenetic studies based on cp DNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former Celtidaceae family, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato. The psychoactive effects of cannabis are known to have a triphasic nature.
