СЕМЕНОВОДСТВО МНОГОЛЕТНИХ ЗЛАКОВЫХ ТРАВ В ТАЕЖНОЙ ЗОНЕ ТОМСКОЙ ОБЛАСТИ

Abstract

The main goal of breeding and seed-growing work with perennial grasses is the creation and reproduction of intensive varieties that are distinguished by high productivity, adaptability, and resistance to adverse factors. The tasks of varietal seed production of perennial grasses in the taiga zone include the preservation of biological and economically useful properties inherent in the variety during its reproduction; ensuring timely implementation of variety change and variety renewal; accelerated multiplication of seeds of new varieties. It is important to cultivate each crop according to modern scientifically based varietal technologies that are developed for the conditions of the region. To create highly productive seed herbage and successful harvesting, it is necessary to take into account the biological characteristics of species and varieties. The choice of seed farming methods is determined by the ability of populations to retain their valuable properties in the process of seed reproduction. When developing promising methods of seed production of new generation varieties, it is necessary to study the reaction of plants to stressful phenomena and develop agrotechnical methods that allow plants to adapt to them with a minimum decrease in seed productivity. The development of seed production of perennial cereal grasses in the extreme soil and climatic conditions of the taiga zone contributes to the growth and stabilization of the gross harvest of seeds with high sowing qualities. The article presents the main results for 2015-2019. on perennial cereal grasses in the Narym Department of Breeding and Seed Production of the Siberian Research Institute of Agriculture and Technology - a branch of the SFNCA RAS. Seed growing is carried out according to the traditional scheme. Due to adaptive varieties, the agroecological zoning of seed production is being improved. The aim of this work is to summarize the results of seed production on perennial grasses in the taiga zone of the Tomsk region.
