Abstract
Introduction. The problem of increasing grain production of both food and feed value is the most important task in ensuring the country's food security. Barley is the main grain crop. In solving this problem, along with improving the agrotechnics of its cultivation, the breeding of new varieties that are maximally adapted to local conditions plays an important role.
Object. Spring barley.
Materials and methods. Breeding of spring barley in the Orenburg region is carried out on a site located in the central zone of the region. The soil is ordinary chernozem, medium–sized, clay and heavy loamy. The humus content is 4.2-6.0%. 385 mm of precipitation falls per year, 152 mm in May-August. The sum of temperatures above 10°C is 2560°C. Breeding nurseries are placed according to the predecessor – black steam. Agricultural cultivation techniques recommended for this zone. The main method of work was the classical method of stepwise hybridization followed by directed individual selection. The crosses involve mainly their local material, as well as samples from the world collection of the N.I. Vavilov Institute of Plant Genetic Resources. After the reproduction of the resulting hybrids, the breeding process proceeds according to the classical scheme.
Results and conclusions. Recently, a new variety of spring barley Lekar 3 has been transferred to the state variety testing, which in the competitive test of the 2nd year exceeds the standard variety Natalie in yield and grain type. The new variety, in comparison with the standard, reduces the cost of 1 ton of grain by 410 rubles, increases the profit from 1 ha by 2025 rubles, and increases the level of profitability by 16%.
