Resistance to Tecia solanivora (Lepidoptera: Gelechiidae) in three transgenic Andean varieties of potato expressing Bacillus thuringiensis CrylAc protein.

Transgenic potato, Solanum tuberosum L., plants containing a synthetic cry1Ac gene coding for the Bacillus thuringiensis (Bt) crystalline insecticidal protein were produced and evaluated for resistance to Tecia solanivora Povolny (Lepidoptera: Gelechiidae), the larvae of which attack potato tubers. In total, 43 transgenic lines of commercial Andean potato varieties Diacol Capiro, Pardo Pastusa, and Pandeazúcar were obtained.
