Abstract
Kanamycin resistant plants of Medicago varia A2 were obtained by an optimized procedure for high frequency transformation using Agrobacterium tumefaciens infection of leaf and petiole tissue. Parameters which affected the frequency were explant type, the Agrobacterium strain used and the time allowed for cocultivation. Under optimum conditions, i.e., using the Agrobacterium strain A281 and a 4 day cocultivation period, the frequency of transformed leaflets obtained was greater than 70%.
