The technique of doubled haploids has certain advantages and disadvantages, including the following:

 AdvantagesComplete homozygosity is attainable in a shorter period.Duration of the breeding program can be reduced by several (two to three) generations.It is easier and more efficient to select among homogeneous progeny (versus heterogeneous progeny in conventional breeding).The cultivar released is homogeneous.

 DisadvantagesThe procedure requires special skills and equipment in some cases.Additional technology for doubling may increase the cost of a breeding program.Frequency of haploids generated is not predictable.There is a lack of opportunity to observe line performance in early generations prior to homozygosity.
