EUROPEAN APPROVED HEMP CULTIVARS AND MEDICAL C. SATIVA

Unlike medical cannabis abundant in the psychoactive ingredient, D9-THC, modern hemp has been selectively bred to produce low levels of D9-THC and high levels of fiber, seed, and more recently cannabidiol (CBD). Most of the Europe Union and Canada have recognized the value of hemp and have defined a legal limit of 0.3% D9-THC in the dry plant material,(Small & Marcus, 2003) with the exception of Italy (0.2% D9-THC) (Cappellettoet al., 2001). Many hemp cultivars are rich in cellulose used for biofuel, primary fibers for pulping, fine fiber textiles, dense flowering varieties that offer abundant seed, or high CBD to D9-THC ratios. Hemp varieties resistant to drought, high soil salinity, cold, heat, humidity, and common pests and diseases have been selected to improve yields (Watson & Clarke, 2014). To date, 51 hemp cultivars have been approved for commercial use by the European Union (Directive, 2013). These registered varieties originate from high latitude European nations, which are not acclimated for equatorial regions of the world. Little is known about the viability of the European cultivars in the United States, and is currently being examined by agronomists.
