Adaptation of Serbian winter pea (Pisum sativum) varieties in the foothills zone of southeast regions of Kazakhstan

In recent years, a large number of varieties and hybrids of agricultural crops of domestic selection with a good yield potential have been allowed for use in production. However, their widespread introduction into production did not lead to a steady increase in yield. This study presents the adaptation of Serbian winter pea varieties “NS Moroz”, “Partner” and “Kosmaj” was conducted during the 2020–21 in the conditions of the foothill zone of the southeast of Kazakhstan. The Kazakhstan variety of spring peas Shal (Kazakh Research Institute of Agriculture and Crop Production) recommended for use in the Almaty region was selected as the standard (control). Good winter hardiness (86%), lodging (4.6 points), structural indicators of the yield and the maximum grain yield (37.2 c/ha) were recorded in the winter pea variety of the Serbian selection of the grain direction “NS Moroz”. In the winter pea variety of the fodder direction “Kosmaj”, winter hardiness was 89% and lodging - 3.0 points, and a high yield of green and dry matter was obtained, respectively 267.7 and 86.9 c/ha. According to the results of the study, the varieties “NS Moroz” of the grain direction and “Kosmaj” of the fodder direction were selected, which are recommended for further introduction into production in the south-east of Kazakhstan. Furthermore, an assessment of varieties of winter peas should be carried out to identify the most productive and valuable for a number of economically valuable traits, followed by a recommendation for their introduction into production.
