Analysis of Intraspective Polymorphism in Barley for Resistance to Cadmium
Phytotoxicity of heavy metals is one of the factors limiting the yield and nutritional value of agricultural crops. The phytotoxicity of cadmium was evaluated for 50 selectively remote varieties of spring barley of different geographical origin from the collection of the All-Russian Research Institute of Crop Production. The presence of pronounced intraspecific polymorphism of spring barley in this indicator is shown. On the basis of the analysis of the morphological parameters of the seedlings, the varieties with contrasting resistance to the action of cadmium were identified.
