Using the unfertilised ovule culture of 4 genotypes of Brassica oleracea var. capitata (three consanguine lines and one hybrid) haploid plants diploid and mixoploid plants with gynogenetic origin were successfully obtained. A larger number of embryos/callus/ovules and normal plants were obtained. The gynogenesis in vitro through unfertilised ovule culture can be an effective method of production of haploids and dihaploids at white cabbage.
