Klymchuk M. Improvment of evaluation methods and the development of breeding material of winter rape in the western Forest-Steppe.

Subject - details of the manifestation of characters and features of varietal samples of the winter rape collection in the conditions of the western Forest-Steppe, the determination of sensitivity of valuable varietal samples to the method of isolated microspore culture. The purpose - the development of parental material of winter rape with the higher productivity and improved biochemical seed composition. The methods are field and laboratory with the use of biotechnological and statistical ones. The value and novelty of investigations is an improved method of isolated microspore culture for the development of dihaploid breeding material of winter rape. The introduction - the developed parental material and valuable varietal samples of winter rape are turned over to the National Centre of Genetic Resources of Ukraine and other breeding institutions. Field of application - breeding scientific institutions.
