Does anyone work with doubled haploid barley production? I’m looking for optimum media or shock pretreatment of ears/anthers. I have used cold pre-treatment for 14 days at 4°C before, 0.3M liquid mannitol and 0.7M solid mannitol. Any suggestions?
I have used 0.7 M mannitol followed by FHG medium + Ficoll 400 in the laboratory of Luis Cistue, and it worked very well (except for some genotypes generating a high percentage of albino plants).
The detailed method is published in the book 'Doubled Haploid Production in Crop Plants' (2003), pp 29-34.
