Biochemical, immunological and physico-chemical properties of an ancient wheat grain – hulless spelt cultivar Gremme are investigated. Biochemical analysis of grain revealed a high content of protein, fiber, macro-and microelements, a rich composition of essential amino acids, which is characteristic of ancient wheat species. Evaluated milling and baking properties of spelt flour. Physical and chemical parameters of spelt grain met the requirements for soft wheat grain class 1: the mass fraction of gluten-38.7 %, the nature of the grain-795 g / l, the number of drops-416 C, the total vitreousness-70 %. However, gluten had an increased stickiness, which is obviously due to the increased content of fiber and gliadin fraction. Grinding of spelt grain was carried out on the aggregate mill installation "Miller 100 Lux" to obtain baking flour of various cultivars. The overall yield of flour of the first grinding was 59.7 %. The highest volume yield (359 cm3) and the best organoleptic properties (total baking score – 3.6 points) were observed in a sample of bread baked from spelt flour that meets the requirements for wheat baking flour of the first grade. Studies have confirmed the possibility of using flour produced from the spelt grain of the Gremme variety for the production of bakery products of increased biological, therapeutic and prophylactic, nutritional value and with a high organoleptic rating. Cereals and flour are very rich in trace elements-manganese, selenium, zinc, potassium, iron, phosphorus, vitamins from group B and B, essential amino acids (biochemical analysis was carried out by the Cherkizovo Center). The cultivar is resistant to drought, heat, excessive moisture. Proved immunological properties to several diseases in the field and laboratory conditions-resistant to enzyme-mycotic seed depletion (EMIS), various types of rust, powdery mildew.

The results of a long-term study of collection samples of spring wheat from the VIR gene pool are presented. Origin of samples from Russia, USA, France, Mexico, India, Sweden, Germany, Czechoslovakia, Kenya, Australia, Belgium, Ukraine, Netherlands, Switzerland, Poland, Finland, Brazil, UK. By means of personal contacts a large specimen of Faraon (USA) was obtained. In the process of studying the varietal population, a biotype was isolated, which was improved by the desired economically valuable traits. The biotype of the Pharaoh is distinguished by a large grain, the mass of 1000 grains is 50-70 g. The protein content is 15-18%. The vitrification is 99%. At the same time it is resistant to a complex of diseases - powdery mildew, brown rust, enzymatic mycosis seed depletion (EMIS). Technological evaluation of the biotype showed the possibility of using it for macaroni purposes. BR-34 (Brazil) has been isolated biotype, studied biochemical and technological properties. Evaluation of the collection from different countries revealed the following: samples from Germany, the Netherlands, England, France, Sweden, Poland, the USA are late-ripening, short-stemmed, with a low mass of 1000 grains and yield. Samples from the USA stand out against brown rust. Samples from Mexico are short-stemmed. Samples from India are donors of short stalk and productivity. Highlighted samples on early maturity, coarse grain, short stalk, weight of 1000 grains, yield, resistance to diseases are recommended for use in breeding programs at the Moscow Research Institute of Nemchinovka and other research institutes.
