Variation of biological and economic yield in wheat cultivars

Abstract

Biological yield (biomass) in terms of dry-matter (straw+grain) yield and grain yield measured in weight per unit area (g m-2, kg ha-2), variate in dependence of genotype, environments and interaction of genotype/environment (Fischer et al., 2012). Breeders are focused on increasing above ground biomass and grain yield. Genetic constitution of cultivars, soil fertility, nutrient, efficiency of absorption of mineral elements and water are in relationships to synthesis of organic matter, translocation and reutilization for production of dry matter i.e. biological and economics yield are important factors (Katsura et al., 2010; Knežević et al., 2015). The aim of this study was to evaluate the variability of mass of plant (biological yield) and grain mass plant-1 (economics yield) in genetically divergent wheat cultivars grown in different environmental conditions
