摘要

We investigated the anther culture (AC) efficiency of thirteen F 4 combinations of winter wheat ( Triticum aestivum L.). The genotype dependency was assessed during the induction of the androgenic entities, i.e. embryo-like structures?(ELS), regenerated-, green-, albino-, and transplanted plantlets. The number of green plantlets per 100?anthers (GP/100A) varied from 0.36 to 24.74 GP/100A with a mean of 8.31 GP/100A. Albino plantlets (AP) occurred in each combination, ranging from 0.20 to 22.80 AP/100A with an average value of 5.59 AP/100A. Between 25–87.76?doubled haploid (DH) plants per 100 acclimatised plantlets (DH/100ADP), depending on the combination, with a mean of 59.74% were recovered. We have found the highest DH production in the combinations Béres/Midas, Kalász/Tacitus, Béres/Pamier, and Premio/5009. This improves remarkably the choice of basic genetic material in subsequent crossing programmes. These observations emphasise the usability and efficiency of in vitro AC in producing a large number of DH lines for breeding and the applied researches of winter wheat. Although albinism was found in each combination, it was mitigated by the in vitro AC application.
