The aim of this study was to determine the effect of genotype and induction medium in anther culture of wheat (Triticum aestivum L.). Ten F1 winter wheat genotypes were tested in anther culture (AC) to compare the two most frequently applied induction media (W14mf and P4mf). Androgenesis was induced during the treatment of each tested genotypes and green plants were produced from them using both media. Based on statistical analysis, the genotypes significantly influenced (at the 0.001 probability level) the efficiency of AC (embryo-like structures (ELS), albinos, green plantlets and transplanted plantlets) and the media also had a significant effect on the number of ELS and albino plantlets. Both media can be used for AC in wheat doubled haploid (DH) plant production. The production of ELS and green plantlets was higher in P4mf medium (48.84 ELS/100 anthers, 4.82 green plantlets/100 anthers) than in W14mf medium (28.14 ELS/100 anthers, 4.59 green plantlets/100 anthers). However, the green plant regeneration efficiency of the microspore-derived structures was 16.9% when using W14mf medium, while this value was 9.6% in the case of ELS induced with P4mf medium. The application of W14mf medium thus proved to be time- and labour-saving medium in the large-scale production of DH wheat plants. In our experiments, 267 DH plants were produced for our winter wheat breeding program. The spontaneous rediploidization rate was 32.72%.
