Camelina sativa
(L.) Crantz], a member of the Brassicaceae family, has a unique oil profile that has potential both for biofuels and as a food crop. It is essential to have a doubled haploidy protocol in order to enhance breeding of this crop for prairie conditions as well as improve the yield and quality characteristics. Microspore-derived embryos have been produced from
Camelina sativa
. Buds 1–3 mm in length were selected for culture. The microspores were isolated and purified in full-strength B5 extraction medium and cultured in NLN medium with 12.5% sucrose and 12.5% polyethylene glycol 4000 (PEG) without glutamine, at a density of 10,000 microspores per mL. Glutamine was added to the cultures 72 h after extraction to give a final concentration of 0.8 g/L. The microspore cultures were maintained at 24°C in the dark. After 28 days embryos were observed and these were regenerated to plants and selfed seed was produced. The highest embryogenic frequency achieved was 38 microspore-derived embryos from 100,000 microspores. |
