clones produce male fertile hybrids when the haploids
are the male
Sacristan & Hoffman  studied direct infection of embryogenic tissue cultures of haploid
Brassica napus with resting spores of Plasmodiophora brassicae.
All 276 clinical strains tested as haploid
MAT[alpha] by CE-FLA.
Among many ants, bees, wasps, mites, and thrips, for example, unfertilized eggs develop into haploid
males, which have just one set of chromosomes.
The use of potato haploids
to put 2x wild species germplasm into a usable form.
One of the haploid
plant production methods is anther culture in vitro used as a complementary suitable method in traditional breeding programs[9,17] that with production of diploid and haploid
callus and/or direct regeneration is possible.
, including ants, wasps, and bees, inherit only their mother's chromosomes.
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.
ABSTRACT The conditions for induction of gynogentic haploids
and restoration of gynogenetic diploids, were studied in the small abalone, Haliotis diversicolor supertexta.
Meiotic chromosome behavior in species, species hybrids, haploids
, and induced polyploids of Gossypium.
The identified linkage groups corresponded to the expected haploid
number of 16(n) chromosomes (Fig.
Mapping of two genes for resistance to clubroot (Plasmodiophora brassicas) in a population of doubled haploid
lines of brassica oleracea by means of RFLP and AFLP markers.
