| Sumario: | Approx. 2 000 olive (Olea europea L.)
varieties are known in the world. Due to the
commerce, promotion of old varieties and the
development of new phenotypic variants, a
situation of uncertainty exists regarding the
correct identification and denomination of
some cultivars. In the last years the Argentine
olive-cultivated area has been triple folded.
Most of the plant materials came from local
nurseries and some from importation. In order
to test the genotypic homogeneity of the
materials commercialized by the local
nurseries, plant samples from 5 of them were
tested using 7 reproducible RAPD markers.
These markers were previously developed
for characterizing cultivars from the
germplasm bank of INTA Junín. Only
samples from cultivars Arbequina and
Arauco showed complete homogeneity
regarding the markers assayed. Samples
from cultivars Empeltre, Farga and Aloreña
were not genotypically homogeneous,
showing from 2 to 3 different RAPD patterns
per lot of samples. All the varieties tested
from the nurseries, showed differences with
their respective varieties from INTA Junín,
for at least 1 of the samples. Arbequina and
Arauco also shared 100 % of the markers
between them. Therefore it was not possible
to distinguish one from the other by the use
of these markers.
