ПШЕНИЦА МЯГКАЯ ОЗИМАЯ: ЭКОЛОГИЧЕСКАЯ ПЛАСТИЧНОСТЬ БИОЛОГИЧЕСКИХ И ТЕХНОЛОГИЧЕСКИХ МАРКЕРОВ

Abstract

<p>The priority in studying new lines and varieties of common winter wheat was their ecological plasticity by biological and technological markers. It was revealed that for stability and plasticity on the basis of seed production the varieties and lines are divided into stable, narrow and wide-adaptive ones, the latter of which are characterized by a wide range of ecological valence (with high and medium variability and homeostasis, with variance of stability which is close to zero, and with environmental factor plasticity which is greater than one). We studied new cultivars and lines of hexaploid сommon winter wheat from Bila Tserkva National Agrarian University and Nosovka Breeding and Research Station of V.M. Remeslo Mironovka Institute of Wheat by seed production, technological indicators of grain, flour and bread quality. The new perspective highly productive and ecologically plastic varieties and lines of сommon wheat are: Yuvivata 60, Zoriana Nosivska, Nosshpa100, L3-95, KS 14, KS 22-04. According to representative criteria, the most promising genotypes, which are the main products in Forest-Steppe of Ukraine and high-quality raw materials for bakeries and bioethanol were identified. It was found that technological characteristics of grain, flour and bread of new cultivars and lines of common wheat meet the modern requirements for production of dietetic food and bioenergy products, that is important and relevant in the context of food security in Ukraine.</p>
