Abstract Rape (Brassica napus L.) is one of the leading crops. In recent decades, due to stable demand on the world market, it has got a leading value in Ukraine. The introduction of biotechnology in genetics and selection process that helps to find new ways to create promising starting materials is becoming more important. The most effective method of obtaining stable lines is an experimental method of haploidy. In selection haploidy is used to produce homozygous lines in the production of hybrid seeds, as well as transfer of selection process from polyploid to diploid level. Promising method for obtaining haploid — is a cultivation of pollen and anthers in vitro. From anather culture formed embryos, which develop in thе sprouts. It is evident we can receive a combination of the desired types of cytoplasm and genomes with the help of androgenesis only in one or two generations. Нaploidy is closely linked with the selection on polyploid level, effective use of mutagenic factors, the problem of quickly creating of heterotic hybrids and their transfer to a sterile base, the ability to accelerate the selection of perennial plants and selection at the cellular level. This suggests that haploidy is becoming one of the most important areas of genetics and selection of rape seed.
Key words haploidy, apomixis, androgenesis, haploidy lines, source material, rape.
