Introduction to Marijuana breeding. Part 2

Weed has great potential for many commercial uses. According to a survey of available research by Turner, Elsohly and Boeren ( 1980 ) of the analysis Institute of Pharmaceutical Sciences at the School of Mississippi, Weed contains 421 known compounds, and other ones are consistently being discovered and reported. Without further experience of the potentials of cannabis as a source of fiber, fuel, food, commercial chemicals and drugs it appears careless to support eradication campaigns. World politics also threaten Cannabis. Rustic Weed farming cultures of the Middle East, Southeast Pacific Rim, Cen tral America and Mrica face political disturbance and open aggression. cannabis seeds can’t be stored for evermore. If they’re not planted and reproduced every year a strain could be lost. Whales, enormous cats, and redwoods are all protected in preserves established by countrywide and global laws. Plans must also be implemented to guard Weed cultures and rare strains from certain extinction. Agribusiness is excited at the prospect of supplying America’s 20,000,000 cannabis users with domestically grown commercial marijuana. As a consequence, development of uniform patented half-breed strains by corporation rural firms is unavoidable. The ethicality of plant patent laws has been challenged for a while. For humans to recombine and then patent the genetic material of another living organism, particularly at the cost of the first organism, definitely offends the moral sense of many troubled voters. Does the slight recombination of a plant’s genetic material by a breeder give him the prerogative to own that organism and its offspring? In spite of public resistance pronounced by conservation groups, the Plant Variety Protection Act of 1970 was passed and now permits the patenting of 224 plant crops. New amendments could grant patent holders sole rights for eighteen years to distribute, import, export and use for breeding purposes their newly developed strains. Similar conventions worldwide could further threaten genetic resources.

Should patented sorts of cannabis become fact it may be illegal to grow any strain aside from a patent-protected variety, especially for food or medical uses. Restrictions is also imposed such that only low THC strains would be patentable. This will lead to limitations on little scale growing of cannabis ; commercial growers couldn’t take the possibility of stray pollinations from non-public plots hurting a valuable seed crop. Fans of plant patenting claim that patents will spur the development of new types. In reality patent laws inspire the dissemination of uniform strains lacking in the genetic variety which permits enhancements. Patent laws have also fostered severe competition between breeders and the suppression of analysis results which if published could speed crop improvement. A few big companies hold the majority of plant patents. These conditions will make it difficult for cultivators of local strains to take on agribusiness and may lead to the further extinction of local strains now surviving on small farms in Northern America and Europe. Plant improvement in itself presents no threat to genetic reserves. the support and spread of improved strains by giant companies could prove terrible. Like most major crops, cannabis originated outside Northern America in still primitive areas of the planet. Millenia gone humans started to gather seeds from wild Weed and grow them in fields next to the first cultivated food crops. Seeds from the best plants were saved for planting the following season. cannabis was spread by winding clans and by trade between cultures till it now appears in both cultivated and escaped forms in several countries. The pressures of human and natural selection have ended in many distinct strains evolved to unique niches in the ecosystem. Therefore , individual cannabis strains possess unique gene pools containing great potential variety.

In this variety lies the power of genetic inheritance. From various gene pools breeders take the fascinating marks joined into new kinds. Nature also calls on the gene pool to make certain that a strain will survive. As climate changes and stronger pests and illnesses appear, cannabis develops new adaptions and defenses. Modern farming is battling to switch this natural system. When Cannabis is legalized, the breeding and selling of improved types for commercial farming is totally sure. The majority of the areas appropriate for commercial cannabis cultivation already bay their own local strains. Improved strains with an adaptive edge will follow in the trail of commercial farming and replace rare local strains in foreign fields. Local strains will hybridize with introduced strains thru windborne pollen dispersal and some genes will be squeezed from the gene pool. Herein lies extraordinary danger! Since each strain of cannabis is genetically unique and contains at least one or two genes not found in other strains, if a strain disappears the unique genes are lost for all time. Should genetic defects arise from unrestrained inbreeding of commercial strains, new types would possibly not be immune to a formerly unrecognized environmental threat. An illness could spread rapidly and wipe out whole fields concurrently. Extensive crop failure would end in great monetary loss to the farmer and possible extinction of complete strains. In 1970, to the terror of American farmers and plant breeders, Southern corn leafblight ( Helm in thosporium maydis ) spread quickly and surprisingly all though corn crops and caught farmers off guard with no defense. H. Maydis is a fungus which causes minor rot and damage in corn and had formerly had no industrial impact. in 1969 an aggressive mutant strain of the fungus appeared in Illinois, and by the end of the following season its windborne spores had spread and blighted crops from the Great Lakes to the Gulf of Mexico. Roughly 15% of America’s corn crop was wiped out. In some states over half of the crop was lost. Fortunately the sole fields badly infected were those containing strains descended from folks of what corn breeders called the Texas strain. Plants descended from elders of formerly developed strains were only a little infected… The discovery and spread of the Texas strain had revolutionized the corn industry.
