ABSTRACT
DNA fingerprints generated by the Jeffreys' probes, 33.6 and 33.15, indicated the presence of minisatellite-like sequences in the red clover genome. The fingerprints generated by probe 33.6 gave less background and fewer but better defined bands than those obtained with probe 33.15. Assay of a regenerative somaclonal variant (F49R) by DNA fingerprinting with probe 33.6 detected mutation that was unlinked to the regenerative trait. The fingerprints obtained under the applied conditions also demonstrated genetic stability of consecutive generations of the regenerants in tissue culture. DNA fingerprints of F1 plants revealed that each polymorphic band was inherited from either one or the other parent. Both probes distinguished individual-specific genotypes in seven cultivars of red clover. Greater variability in DNA fingerprints was detected between (V=0.899) than within (0.417≤V≤0.548) cultivars.
