Abstract

Resistance to herbicide Basta® was introduced into pure inbred lines of Savoy cabbage (Brassica oleracea L. var. sabauda) by cocultivation of cotyledon and hypocotyl explants with Agrobacterium tumefaciens strains AGL1/pDM805 and LBA4404/pGKB5 (LB5-1). Shoot regeneration occurred on Murashige and Skoog medium supplemented with 1 mg dm -3 6-benzyladenine and 0.5 mg dm -3 indole-3-butyric acid at 42.3 % and 71.4 % of hypocotyl explants treated with AGL1/pDM805 and LB5-1, respectively. Putative transformants that survived selection on 10 mg dm -3 phosphinothricin (L-PPT) supplemented medium were confirmed by GUS assay and PCR analysis. The transformation rate was 58 % with AGL1/ pDM805 and 25 % with LB5-1. Rooted plantlets were acclimated and then again screened for Basta®-resistance by spraying with 15 - 60 mg dm -3 L-PPT. Surviving plants were selfed and Basta®-resistance was demonstrated in T 1 progeny.
