Abstract
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.
Highlights
It is calculated that when the value of protein content in the grain is 9.0%, the starch content is 70.1%, and when the protein content increases to 12.5%, the starch content decreases to 66.5%
With increasing yields per 1 ton, the protein content may decrease by 0.8%
It was found that the protein content on average in the collection nursery was 11.2% with the variability of individual values from 9.3% (Petrol variety) to 12.2%
Summary
Experimental studies were conducted at the NSC “Institute of Agriculture NAAS” during 2017–2019. The value of protein content in the collection samples of winter triticale averaged 11.2% in 2017–2019 and varied in the collection nursery from 9.3% (Petrol variety) to 12.2% (numbers 229 and 205). Over the years of research, significant changes in the content of protein in the grain of the collection samples of winter triticale were observed. It should be noted that the increase in protein in 2019 was observed mainly in grain of the collection samples, which were generally characterized by high protein content, value of which averaged from 11.0 to 12.2% over three years. It was found that such samples with a high starch content as [101, 123], Solodiuk, Petrol, Lubomyr and Arystokrat (on average for three years – 69.0– 70.3%) had a low protein content (9.3–10.9 %). Two varieties Molfar and Volemyr were characterized by average parameters on both grounds: starch – 68.2%, protein – 11.0%, and the variety Maetok Poliskyi had low rates of both starch and protein content (66.8% and 10, 3%, respectively)
