Kyrylchuk A. Genepool of spring rape according to biologocal features and productivity elements for breeding

The research object is a process of forming productivity of different variety samples at the collection nursery of spring rape. The aim is to improve the methods of evaluation of spring rape gene pool on biological signs and elements of the productivity for new varieties creation. The research methods are the field, measuring-weighing, laboratory, mathematically statistical, calculation-comparative. The methods of evaluation of rape spring feedstock are improved on biological signs on the basis of which 3 patents for utility model was obtained. The sources of precocity, determination, high productivity of green mass, seed and fat are distinguished, as well as economic-valuable variety samples contented erucic acid, glucosinolats, an olein and linolenic acids. The author's scientific developments are inculcated in plant-breeding work of NRC "Agriculture Institute of NAAS", 7 standards of feed direction spring rape are transferred at the National center of genetic resources of Ukraine. The field of using is the breeding scientific establishments.
