Can the requirement for stability testing be relaxed in some cases?
Yes, but it depends on the mode of propagation. Experience shows that uniform, asexually propagated varieties are stable. The same rule of thumb cannot be applied to heterozygous sexually produced plants. Accordingly the PBRO only considers applications to waive stability testing for sexually propagated varieties on a case-by-case basis. Where testing for stability is waived, more weight is placed on the assessment of uniformity.
