Use of cell engineering for development of the constant initial breeding material of white head cabbage cv. Nadzeja and CMS-samples

The anther derived androgenic plants of white head cabbage cv. Nadzeja and CMS samples were obtained. The cytological analysis of ploidy level of regenerated plants and doubled haploids obtained by treatment of meristems with colchicine was performed. On the basis of androgenic doubled hap-loids of white head cabbage genotypes the seed plants were developed.
