Slide7Example 1
Possibilities
for DUS-examination in seaweedAim: development of method for DUS-examination in some seaweed species.Conclusion: a protocol for DUS-examination and
variety
description of seaweed has been developed.Fine-tuning of characteristics needed.Not yet clear
if
varieties
are
available
which
fully
fulfill
UPOV-
critera
for
distinctness
,

protocols
are
harmonized
between
the
European Examination Offices,

for
Fusarium
in
pea
.
Isolates
are

Naktuinbouw
has
updated
the
