Many factors influence androgenesis including plant genotype physiological state of the parent plant microspore development stage temperature pretreatment of flower buds and the culture medium (Bajaj 1990).
La ginogenesis y la androgenesis favorece la obtencion de individuos homocigoticos en la primera generacion y lineas clonales puras en la segunda, por tanto, se disminuye el numero de generaciones necesarias para obtener una linea pura y favorece la obtencion de lineas homocigoticas diferenciandose con la hibridacion tradicional.

Although the hybrids between Lolium and Festuca species are usually male sterile with low female fertility (Jauhar, 1993), the androgenesis technique, which produces diploid offspring that carry nuclear chromosomes from only the male parent, was used to select and stabilize useful Lolium-Festuca gene combinations (Lesniewska et al.

Androgenesis could produce paternal ancestor individuals with heterospecific mitochondrial DNA, whereas genome incorporation could disrupt the strictly clonal "meiotic" mechanism of the diploid parthenogen; androgenetic and triploid progeny would thereby provide opportunities for the genetic diversification and evolution of the unisexual hybrid Bacillus.
These homozygous doubled haploids have been induced via either androgenesis (pollen or anther culture) or gynogenesis (ovule or ovary culture) processes, or induced by pollination with irradiated pollen (Islam, 2010; Chen et al.
