Abstract

Results of research of soft winter wheat new lines of hexaploid level by morphological features, biological properties and biochemical parameters were given. During 2018–2020 in the Northern part of the Central Forest-Steppe of Ukraine the assessment of the general adaptive capacity by the yielding capacity and biological-agronomic traits are given and promising ones are highlighted (Donzorna, Flonormyra, Polezoriana). The new wheat lines have proved themselves well given the consistently high winter, drought resistance, and productivity, coefficient of variation is low, variance of stability, homeostaticity, and selection value – high. According to the biochemical composition of the grain, the studied lines are characterized by medium and high ‘raw’ protein content and gluten content. New selection wheat lines own by the technological indicators (the volumetric bread outut of 100 g of drough, the total baking rating), flour ‘quite satisfactory’, ‘good’, and ‘excellent’ score (Sviatdonivka, Flonormyra). The new wheat line Donzorna is characterized by the presence of 1BL/1RS wheat-rye translocation, which distinguishes it as a donor of resistance to biotic and abiotic factors and requires further more detailed study.

Highlights

In the world wheat along with rice are the main food crops, and in many countries of the planet are the leading means of subsistence
Ukrainian wheat in general is inferior in grain quality to the best world varieties and often does not fully satisfy the national market the level of quality of wheat flour (Rybalka, 2011; Szakács et al, 2020) in the selection of soft winter wheat homogeneous genetic material, besides progress in increasing productivity varieties, caused a narrowing of their genetic basis and an increasing the affinity of the gene pool (Ivanova et al, 2019)
The purpose and objectives of our research became a comprehensive study of the new gene plasma of soft wheat (Triticum aestivum L.) winter type of growth for the conditions of the Forest-Steppe of Ukraine by productive, ecological adaptive potential and quality indicators

Summary

Introduction

In the world wheat along with rice are the main food crops, and in many countries of the planet are the leading means of subsistence. Ukrainian wheat in general is inferior in grain quality to the best world varieties and often does not fully satisfy the national market the level of quality of wheat flour (Rybalka, 2011; Szakács et al, 2020) in the selection of soft winter wheat homogeneous genetic material, besides progress in increasing productivity varieties, caused a narrowing of their genetic basis and an increasing the affinity of the gene pool (Ivanova et al, 2019) This led to that the vast majority of domestic varieties have a narrow technological direction of using (Rybalka, 2011; Kozub et al, 2018; Motsny, et al, 2017). The purpose and objectives of our research became a comprehensive study of the new gene plasma of soft wheat (Triticum aestivum L.) winter type of growth for the conditions of the Forest-Steppe of Ukraine by productive, ecological adaptive potential and quality indicators
