Fig. 1 RAPD fingerprinting of white spruce embryogenic clones.
Primers used for RAPD amplification are shown below the
fingerprints for each set of six clones. DNA was extracted from
freshly thawed embryogenic tissue after 4 years in cryopreserva-
tion. Lanes 1–6 represent clones 62, 66, 147, 220, 379, and 525,
respectively. Lane L is a 123-bp ladder
