AGROBIOLOGICAL FEATURES OF A NEW VARIETY OF SPRING BARLEY

Abstract

The selection work has been carried out on the base of the Primorskiy branch of the Federal Center for Integrated Arctic Research of the Russian Academy of Sciences (FCIARctic) in 2005-2016, in a selection seven-field crop rotation. Various weather conditions contributed to a complete and comprehensive assessment of the selected sample. Data on agrometeorological research were provided by the Federal State Budgetary Institution “Northern UGMS” of the Hydrometсenter at the post of Kurtsevo. Assessment of breeding material was carried out by the main breeding valuable traits, taking into account the length of the growing season, resistance to lodging and grain yield according to the methodology of the State Commission for the Testing of Crops (1985).  Statistical processing of the experiment results were carried out using the genetic and selection software package AGROS version 2.07. A new variety of spring fodder barley “Kotlas” with increased adaptability for variable growing conditions was developed, it intended for cultivation in extreme climatic conditions of the Far North as an early ripening, productive, adaptive to unfavorable environmental factors to obtain concentrated feed for livestock and poultry. The variety is immune to net blotch of the Arkhangelsk population. The stability index (L) of the variety is 53. The new variety usage will increase the yield of spring barley, increase the economic efficiency of using the variety to 15%, the economic effect of introducing the variety per unit volume of production is 7.85 thousand rubles.
