The results of using in the breeding process of collection samples of winter triticale in terms of grain quality

The aim of the work was to evaluate the collection samples of winter triticale by protein content and to establish the relationship between its quantity and other valuable economic features. Materials and methods. Collection samples of winter triticale, infrared spectrometry method, mathematical and statistical processing. Results. According to the protein content, the samples was divided into four groups. The average protein content in the collection nursery was 11.2% with the variability of individual values from 9.3% to 12.2%. The average reliable inverse correlation of yield with protein content in grain (r = −0.37) and weak line with starch content (r = 0.17) were established, Conclusions. An inverse relationship of medium strength between starch and protein content has been found. which proves the possibility of selection to increase grain yield without reducing the starch content. An inverse correlation between protein content and grain yield has been shown.
