Formation of grain quality of new varieties of spring soft wheat in the middle volga region

Abstract

Relevance. The article presents the results of studying the formation of grain quality indicators in varieties of competitive testing of spring soft wheat. The purpose of the research is to study local new varieties of spring soft wheat according to the most important quality indicators for the middle Volga region and to identify varieties that consistently form high grain quality for further breeding and seed production.

Materials and methods of researches. The object of research was 36 varieties of spring soft wheat of competitive testing, created in the Volga Scientific Research Institute of Selection and Seed-Growing named after P.N. Konstantinov. The study of varieties was carried out according to the Methodology of the state variety testing of agricultural crops (1985). Grain quality indicators were determined according to current standards.

Results. The greatest variability over the years was observed in the indicators of grain vitreous (C_V = 5.40–10.0%), protein content (C_V = 3.75–10.48%) and gluten content (C_V = 7.62–10.20%), that is, in indicators that depend on growing conditions. As a result of a comprehensive assessment of varieties, valuable sources are identified that annually form high-quality grain. These are the Kinelskaya 59, Kinelskaya niva, Kinelskaya 2010, Kinelskaya yubileynaya varieties included in the register, the Kinelskaya Zarya variety undergoing State testing, and the new promising lines Erythrospermum 3898, Erythrospermum 4112, Erythrospermum 4171, Erythrospermum 5289, Lutescens 6029. The varieties that were selected during the study are recommended for use in breeding programs for creating high — quality forms for contrasting weather conditions, zoned varieties — for wide use in commodity production, new lines-for preparation and transfer to State testing
