Genetic systems affecting the efficiency of starch to ethanol conversion were investigated, a laboratory method for determining the fermentability of grain raw materials and evaluating breeding material according to this characteristic was developed, the basic starting material with high grain fermentability was created, which laid the foundations for the creation of wheat and triticale varieties in Ukraine. distillate direction of technological use of grain. It has been established that grain fermentability is a clearly genetically determined trait, is controlled by a certain number of genes and genetic systems and can be controlled in the breeding process. It is shown that the strongest effect on grain fermentability is caused by the genetic system of waxy genes, which should be taken as a basis in the creation of varieties (hybrids) of grain crops of alcohol-distillate direction of technological use of grain. Hardness genes that control the hardness and physical size of starch granules are also found to increase the fermentability of the grain. It is experimentally proved that the main features that should be used in the selection of cereals for ethanol production are: the content of starch and protein in the grain, its chemical and granulometric composition, the degree of destruction of starch granules when grinding grain, as well as the yield of ethanol on the physical unit of grain and starch . It is established that in terms of ethanol output per unit mass of starch, modern high-yielding wheat varieties are significantly dominated by all other crops, since their grain starch consists mainly of amylopectin type A, which is rapidly and almost completely transformed into ethanol. The use of chromosomal substitution 5V (5D) has been found to be an effective way of inducing genetic variability in triticale and creating high-performance genotypes with high fermentability rates on this basis. A molecular genetic analysis system for the detection of hybrid samples of wheat with high amylose content in the grain was tested, which makes it possible to include them in cross-breeding schemes.
