Grain quality of winter triticale varieties selected by the Samara Research Institute of Agri-cultural Sciences

Abstract

The article presents the results of studies to identify the influence of abiotic factors on the grain quality of varieties and lines of winter triticale of the Samara Research Institute of Agricultural Sciences for 2017-2020, in comparison with varieties of winter rye and wheat. The studied crops were cultivated in the fields of the institute, located in the black earth steppe of the Middle Volga region. Technological properties were determined in the laboratory of the technical and analytical service of the Samara NIISH and at the Faculty of Technology of the Samara State Agrarian University according to standard generally accepted methods. The data obtained indicate a higher productivity of modern triticale varieties, compared to rye and wheat. In terms of grain quality, these varieties and lines are superior to winter rye varieties and are not inferior to wheat. On average, over 4 years, the content of HAC in triticale varieties was (1.09-1.51 mp · S), with a variation by year, depending on climatic conditions from 0.90-1.53 mp · S in 2017 to 1.01-1.59 mp · S in 2018. It was revealed that the varieties Krokha and Arcturus were distinguished by the fat content of 1.81-1.85 %, the variety Spika and liniya 9385-4/14 1,72-1,75% – by ash content. In terms of the content of almost all amino acids, the grain of the 830-4/13 line was superior to the rest of the studied samples. The amount of protein in the grain varied from 11.7 to 15.6% over the years, and fat from 0.61 to 2.55%. A high yield relationship was observed with the content of pentosans r=-0.82±0.08, arginine r=-0.72±0.12, with the mass of 1000 grains r=0.67±0.14, histizine r=0.61±0.16, leucine r=-0.69±0.13, sodium content r=0.86±0.06, and depended on the amount of precipitation in April r=0.81±0.08. The necessity of analyzing the amino acid composition of triticale grain to determine its biological value is justified
