Abstract:

Four different ecotypic garlic cultivars ‘modified garlic’, ‘Jintang early garlic’, ‘Cangshan’ and ‘Europe 01’ were chosen to select for the resistant paraquat callus, in the medium including paraquat concentrations 0.2%, 0.4%, 0.6%, 0.8%, 1.0% and 1.5%, respectively. The results showed that the four cultivars had some resistance under the low concentration stress (﹤0.4%), and the resistance of the callus were enhanced by step-to-step culturing method. The survival rates of the callus were from 7.8% to 20.6% in the medium including containing 0.6% paraquat. Some callus was also survived in the medium containing 0.8% and 1.0% Paraquat. Stability Test showed the ability of resistant paraquat could keep for a long time.
