Analysis of the formation of productivity of artificially created mixtures in different biotypes of barley
Year: 2021
Type: conference-paper
Abstract: The research used four varieties of barley, two varieties from the selection of the Krasnoyarsk Research Institute of Agriculture - Vulkan, Bahus and two varieties - of SibNIIRS - Acha, Biom. A four-component mixture of biotypes originally in equal proportions was composed of them. The aim of the research was to study the significance of biotypes in the formation of the productivity of artificially created mixtures and to isolate the most valuable source material for breeding work. Field assessment of biotypes was carried out in 2016-2020. in the forest-steppe zone of the Krasnoyarsk Territory. Spectra of hordeins were identified and recorded as genetic formulas (HRD A.B.F.). Changes in the biotypic composition of the studied mixture were noted already in the first year of reseeding. An increase in the proportions of two biotypes of the Novosibirsk selection 12.1.3 (1.62) and 24.8.2 (1.11) was revealed, while the proportion of biotypes of the Krasnoyarsk selection 2.25.1 and 18.67.1 decreased in equal values, amounting to (0.62), this tendency was traced throughout the entire period of the ongoing research. The differences between biotypes according to the formulas of hordeins reflects not an accidental, but a natural character, which indicates the ecological significance of the used protein markers and the importance of taking into account the variants of the spectra of hordeins when selecting parental forms and carrying out breeding work to create new varieties adapted to growing conditions. As a result of the research, two biotypes 12.1.3 (Acha), 24.8.2 (Biom) were highlighted which are of the greatest value for barley breeding as a starting material.
