 The full range of genetic segregation of interest to the plant breeder is observed because only a small fraction of androgenic grains develops into full sporophytes.

 High rates of albinos occur in cereal haploids (no agronomic value).

 Chromosomal aberrations often occur, resulting in plants with higher ploidy levels, requiring several cycles of screening to identify the haploids.

 Use of haploids for genetic studies is hampered by the high incidence of nuclear instability of haploid cells in culture.
