Selection ideatype of a new variety of oil flax adapted to forest-steppe conditions

Abstract

Goal. To create a new ideatype of oilseed flax, which will increase seed production in the Forest-Steppe with high yields, seed quality, and disease resistance. Methods. Field method — to determine the interaction of the subject of research with natural and agronomic factors; measuring and weighing — to determine the height of plants, yields of straw, fiber, seeds; settlement-comparative — for the economic evaluation of cultivation of different varieties of flax; statistical, dispersion — to identify the reliability of the results of experiments. Results. Based on field researches of the registered modern varieties of oil flax the key economically valuable signs which were used for the creation of a selection ideatype of a variety of oil flax adapted to the Forest-Steppe zone are allocated. Valuable selection lines of oil flax, which have a set of valuable features and significantly exceed the variety standard for productivity, are selected according to the main parameters of the ideatype in the selection process. Conclusions. Based on field researches and data of laboratory analysis the selection ideatype of a variety of oil flax adapted to conditions of the Forest-Steppe zone is developed. The proposed model can be used at the preparatory stage of selection — in the selection of parental forms for crossing, and directly in the selection process — in the selection of plants among different generations of hybrids in selection nurseries, and in the assessment of the resistance of varieties to biotic and abiotic factors, which was used in selection work of the NSC “Institute of Agriculture of NAAS”.
