STUDY OF NEW FIBER FLAX VARIETIES

Abstract

Results are given from investigations carried out in 2012-2014 at the Ivanovo State Agricultural Academy (Ivanovo, Ivanovo Region) in accordance with the methods for conducting field fiber flax experiments. The purpose of the research was to study varietal distinctions in the formation of yield in new fiber flax varieties bred in Netherlands (Suzanna) and Belarus (E-58), and to determine their adaptation to conditions of the RF regions by way of example of Ivanovo Region. The tasks were to find out differences in the plant height, accumulation of air-dry weight, formation of the yield structure elements, seed, straw and fiber productivity, quality of fiber products, resistance to lodging and diseases. The varieties studied showed high adaptation to conditions of Ivanovo Region. The variety Suzanna was characterized by high straw and fiber productivity as well as by product quality. The variety E-58 had high seed productivity potential. Both varieties are resistant to lodging and plant diseases, their cultivation being economically justified. The varieties are responsible to organic fertilizer aftereffect. The placement of the crop in a year after manure application contributed to stable high fiber productivity. On the basis of the findings, the variety Suzanna can be recommended as a promising one for Ivanovo Region, and included in the variety trial. The variety E-58 should be studied further taking into account the peculiarities of its cultivation.
