Selection and breeding of cereal crops for bioethanol production The goals of the project are assessment of suitability of varieties and breeds of cereals (barley, oats, witer and spring wheat, winter rye, triticale) for use in bioenergy production and selection of initial breeding material for establishment breeding programme for bioethanol production. The starch content of cereal grain was in average 2-3% lower that in 2007. Highest starch content had varieties of spring and winter wheat and winter triticale varieties. Starch content in grain of winter wheat varieties Ada, Björke ja Kosack ning triticale varieties Fidelio, Lamberto, Moreno ja Ulrika exceeded 70% in dry matter bases. Winter cereals have almost double biothanol yield compared with spring cereals. Bioethanol yield of analysed varieties ranged between 3283-4756 (Lamberto) l/ha in winter triticale, between 3059-4143 (Björke) l/ha in winter wheat and between 1840-3216 l/ha in winter rye varieties. Despite of lower bioethanol yield the winter rye varieties are of further interest because of lower demand on agrotehnology and suitability for less fertile soils. The further selection is concentrated in identification of best suited winter crop varieties. Further analyse of collection varieties and advanced breeding lines of winter wheat, triticale and rye is in progress to identify the highest yielding, disease resistant genotypes with high starch content. Initiation of breeding program in red canary grass for energy production The goal of the studies is use of red canary grass natural ecotypes for establishment of breeding program of high yielding stalk-typed varieties with low ash content for energy production. Cultivation of red canary grass for bioenergy production enables taking into the use of currently set to side and non-used lands. The limiting factor of existing fodder type varieties is high yield losses during the winter. The use of stalk-typed, lodging resistant varieties will substantially increase the productivity and efficiency of cultivation. Initial selection nursery from natural ecotypes collected in 2007 from 36 locations was created. The first analyses for suitability of ecotypes for energy production could be obtained in autumn 2009. Suitability of hemp varieties for bioenergy – yield and energy production. The biomass yield and energy production of hemp variety Santhica 27 was tested at different fertilizer inputs and in different soils. The harvestable energy production of hemp was in same level with the best cereal varieties and with red ganary grass. Hight production cost of hemp (high price of the seeds, demand for specific mashinery) makes the hemp less profitable for energy production than cereals or red canary grass.
