Uses of Haploids - As a result of haploid induction followed by chromosome doubling, homozygosity can be achieved in the quickest possible way making genetic and breeding research much easier. The genetic segregation is simplified in homozygotes, recessive genes not being masked by dominant ones.

Homozygosity is still more important for those plants which have a very long juvenile phase, such as fruit trees, bulbous plants, and forest trees. Even though, homozygosity can be achieved through self pollination, it is a long process in such plants. As a result of homozygosity, lines which produce pure F1 hybrids are made possible.

When working with plants that are normally polyploid, it is very useful by haploid induction to work at a low ploidy level. Monoploids have an advantage for the mutation breeder in that recessive mutations are immediately discernible.
