摘要

The influence of different factors on microspore embryogenesis in Chinese cabbage (B. rapa ssp. chinensis) was studied. A genotype dependence for embryo formation was observed. The majority of embryos and plants were obtained from microspores isolated from flower buds (2-2.9 mm in length) and cultured in the NLN liquid medium with 13% sucrose (w/v) supplemented with 24-epibrassinolide and 1% activated charcoal. Embryos cultured on the 1/2 Murashige-Skoog culture medium with 2% sucrose (w/v), 0.1 mg/L benzylaminopurine, and 3 g/L Phytagel stimulated the formation of secondary embryos that resulted in development of large number of doubled haploid plants.
