In maize breeding use of doubled haploids (DH) is very important as these are shortening the time for development of inbred lines.
Kucera (2004).Production and utilization of doubled haploids in Brassica oleracea vegetables.
The subsequent exposure of the activated eggs to the sublethal temperature or high hydrostatic pressure enables the recovery of the diploid state in the zygotes by inhibition of the second polar body release or suppression of the first mitotic cleavage and production of heterozygous gynogenotes and homozygous gynogenetic doubled haploids (DHs), respectively [2].
One of the most popular methods for production of haploids is through anther and microspore culture on the artificial culture medium.
Haploids are interesting for fundamental research, but their main utility is to produce DH lines, which are extremely useful tools for basic and applied research, including breeding programs (Chupeau et al., 1998; Dunwell, 2010; Forster et al., 2007; Touraev et al., 2001).

ABSTRACT The conditions for induction of gynogentic haploids and restoration of gynogenetic diploids, were studied in the small abalone, Haliotis diversicolor supertexta.
