Opis:
Using in vitro androgenesis serves as a unique opportunity to produce doubled haploid (DH) plants in many species. More benefits of this biological phenomenon have kept these methods in the focus of fundamental research and crop breeding for decades. In common wheat (Triticum aestivum L.), in vitro anther culture is one of the most frequently applied DH plant production methods. The efficiency of in vitro wheat anther culture is influenced by many factors, such as the genotype, growing conditions, collection time, pre-treatments, and compositions of media and culture conditions. According to some critical review, the genotype dependency, low efficiency and albinism are mentioned as limitations of application of the anther culture method. However, some research groups have made significant efforts to diminish the effects of these bottlenecks. Due to the improvements, a well-established in vitro anther culture method can be an efficient tool in modern wheat breeding programs.

Opis:
This paper briefly cites the various procedures for the production of doubled haploids in barley and wheat. Various associated terms are defined and the factor involved in haploid production are outlined. Isolated microspore cultures offer some advantages over anther culture. Our current procedures for isolated microspore culture of barley and wheat are presented and compared.

Opis:
With the numerous improvements in cereal tissue and wheat anther culture, it is necessary to determine which of the improvements should be combined for optimal response. This study was conducted using one highly responsive cultivar of wheat (Triticum aestivum L. cv. Pavon 76) to test the effectiveness of pre-culture cold treatment (0 or 3-7 days at 5°C) of anthers, five initiation basal media, and various changes in Murashige-Skoog regeneration media. A cold pre-culture treatment was inhibitory for all initiation media for embryoid initiation. Of the initiation media, P1, 85D12, and N6 were similar for embryoid initiation (0.80 to 0.90 embryoids/anther) without a cold pre-culture treatment. Plant regeneration was improved by the addition of amino acids or glucose, increased sucrose concentration, filter sterilizing the medium, and altering plant growth regulator concentrations. P1 medium which is normally used for embryoid initiation was also beneficial for improving plant regeneration. Ethylene inhibitors were generally not beneficial.

Opis:
The influences of genetic and environmental factors on the anther culture responses of wheat were investigated. Significant differences for callus induction, plant regeneration, and green plant percentages were observed when the nucleus of Triticum acstivum L. cv. Selkirk was transferred to ten alien cytoplasms by substitution backcrosses. In most cases, the alien cytoplasms decreased anther culture responses, but sometimes they were as good as or better than the T. aestivum cytoplasm. Significant within-genotype variation for anther culture responses were observed for wheat varieties Chris, Yecora Rojo, WA7176 and Edwall, indicating genetic heterogeneity in the present commercial cultivars, and potential for improving anther culture responses by in vitro prescreening. When five genotypes (Chris, Pavon 76, Butte 86, WA6916, and Edwall) were cultured across three (potato-4 liquid, 100 g L⁻¹ ficoll-supplemented, and 6 g L⁻¹ agar-solidified) induction media, the liquid and ficoll-containing media were 10 to 15 times more productive than the agar-solidified medium. Whereas, the ficoll medium was not significantly different from the liquid medium. Several low concentration starch media appeared promising to replace current induction media. The starch media sustained the highcallus-induction properties of the liquid medium, while improving callus aeration similar to that observed on solid media, resulting in markedly higher plant regeneration and green plant percentages.

Opis:
The use of 2,4-D as a post pollination treatment to fertilize florets instead of GA₃ provided a two-fold improvement in seed set, culturable embryos and hence green plant production from wheat and maize pollination. The efficiency of the wheat by maize pollination method for haploid production was equal to the anther culture method in F₁ hybrid combinations that were responsive to anther culture. However, in recalcitrant combinations obtained from non-responsive genotypes the maize pollination method was far superior.
