Ecological pea adaptibility in grain protein content in agrolandscapes of the Khakas Republic

In the study the results of ecological variety trial of 17 pea varieties undertaken in the three points located in the forest-steppe (point “Tashtyp”), steppe (“Shira”) and dry-steppe (point “Zelenoe”) zones of the Khakas Republic in 2016-2017 are presented. The three-way analysis of variance has allowed establishing the share of the influence of variability factors (year, point, variety) on protein deposition in grain of 17 pea varieties. In total from the experiment the protein content in pea grain was 25.2 % in 2016 and 26.04 % in 2017. “Point” factor pro-moted protein deposition in grain by 22 %. During two years of research the average protein content was regis-tered within 24.93 % in the point of “Shira”, 26.12 % in the point “Zelenoe” and 25.85 % in the point “Tashtyp”. Va-rietal differences determined the symptom forming only by 9 %. From experiment varieties Radomir, Yakhont, Omsky 18, Agrointel 2, Buslay and Krepysh had the average protein content in grain about 26 % in total...
