| Abstract: | The genetic manipulation of lettuce (Lactuca sativa) necessitatesa reliable and efficient, genotype-independent method of transformation.Thirteen lettuce cultivars have been assessed for their amenabilityto Agrobacterrum-mediated gene transfer linked to their tissueculture responsiveness, including callus induction and shootregeneration. A reliable protocol has been developed for theroutine production of transgenic plants for all 13 cultivarsinvestigated. Key words: Agrobacterium-mediated transformation, Lactuca sativa genotypes, lettuce |
