Breeding value and homeostaticity of Ukrainian and Western European winter bread wheat varieties by spike performance

Purpose and Objectives. The purpose was to evaluate the breeding value homeostaticity of grain weight number per spike in modern Ukrainian Western European winter bread wheat varieties identify adapted Eastern Forest-Steppe Ukraine sources strong expression these traits.
 Materials Methods. Twenty-eight short-stemmed (Triticum aestivum L.) accessions from three countries - fourteen accessions, seven Germany, France were investigated. studied by appropriate methods using general-scientific, special genetic-statistical research.
 Results Discussion. It determined that portion with genotypic ability show high combination a large grains among domestic 42.9%; such included Prydniprovska, Blahodarka Odeska, Rodzynka Odeska (UKR) others. A lot this trait recorded for Nota Manera (UKR); accounted 35.7%. Accessions ecotype weights lots did not combine theses features traits, therefore less valuable.
 Conclusions. revealed varieties, showed spike, which makes them valuable starting material breed highly productive promising Ukraine.
