through many generations. Breeder: Mr. A.A Pouw, De

Choice of Comparator ‘Kordaba’ A syn Lambada A was
initially considered as a comparator, however it was not
finally included in the trial as it significantly differs from
the candidate in the following characteristics: anthocyanin
colouration being weak to medium with a reddish purple
hue compared to very strong and purple in the candidate.
‘Tennessee’ A was finally chosen as the sole comparator as
it is in the opinion of the qualified person the most similar
cut flower variety of common knowledge on the basis of
flower colour.
Comparative Trial Comparator: ‘Tennessee’ A . Location:
Cranbourne, VIC, Jul – Dec 1999. Conditions: plants grown
in the soil within environmentally controlled glasshouse.
Measurements: 20 random samples of each variety
collected over a five month period.
