In the last years, the issue of the protection of varieties as an intellectual property on the territory of the Republic of Moldova is of great importance. And since the Republic of Moldova has very few own fossil energy resources, the problem of using renewable energy sources has been and remains very current. For biomass production on an industrial scale, it is necessary to select, improve and implement energy crops that use to the maximum the active photosynthetic solar energy during the vegetation period, accumulate a considerable quantity of dry substances with optimal and reduced founding, maintenance, harvesting and processing costs. At present, about 100 species of plants are identified in the Botanical Garden and which can be used for the production of various types of biofuel. The species Miscanthus giganteus was highlighted among them, which is a perennial herbaceous plant and can be kept on the same field for more than 15 years. It is vegetatively propagated by pieces of rhizomes or plantlets produced by tissue culture (seedling). The plantation of Miscanthus is placed on deep-cultivated, waterlogged soils. In accordance with the variety examination procedure approved by the Law on the Protection of Plant Varieties, a National Test Guidelines for Giant Miscanthus, which meets the most important biological and physiological developmental features, has been developed for the Republic of Moldova.
