Crossing of cereals depending on hydrothermally conditions

Abstract

The results of the hybridization of wheat with rye soft spring ardent depending on weather conditions. Differences weather assessed by hydrothermal coefficient G.T. Selyaninova (SCC). Summarized results indicate that the zone of steppes of Ukraine the main factor that determines the level of potential genotype is the weather. Remote hybridization – a fundamentally new method for plants that combine genetic basis in its most valuable features and characteristics of wild and cultivated plants - the product of a long evolution of natural and artificial selection. Many varieties of wheat grown in Ukraine no longer meet the needs of modern agricultural production, especially resistance to diseases and adverse weather conditions - drought, low and high temperatures. In this regard, distant hybridization is one of the most promising ways to create varieties of intensive type of broad ecological plasticity, high yield and quality. Therefore experimental distant hybridization has become necessary and urgent in wheat breeding.
