CHARACTERISATION OF A WEIGELA THUMB. COLLECTION

A collection of 73 cultivars and species has been established for DUS (Distinctiveness, Uniformity, Stability) testing. Analysis has been made on the intra-varietal fluctuation and interactions with environment for morphological characters used following UPOV rules.

Mutations have been observed and characterised. Introduced clones have been properly identified.

Consequences are given on studies developed as part of Plant Variety Rights.
