Abstract
This experiment was carried out comparison with haploid plants productivity by microspore culture among domestic cultivars of Brassica napus L. Isolated microspore from flower buds were cultured on NLN medium supplemented with 13% sucrose, $0.05mg/{\ell}$ BA and $0.5mg/{\ell}$ NAA. Genotype was important factor in haploid embryo productivity 'Tamlayuchae' showed the highest haploid embryo production frequency (176 embryos formed from 1 flower bud). But, 'Hallayuchae' and 'Youngsanyuchae' were not generated embryo even cell division. When suspension culture on NLN liquid medium at 100 rpm, embryos were developed multilobe abnormal embryo cluster. Multilobe abnormal embryos on MS medium basal solid medium were regenerated multiple shoots. Regenerated haploid plant with well developed shoots and roots on MS basal medium were successfully transferred to pots.
