Choice of Comparators The grouping characteristic used
in identifying the most similar varieties of common
knowledge was – Flower: main colour of inner side of inner
tepal red-purple. Based of this ‘Barbaresco’ A and
‘Stargazer’ were selected as comparator varieties.
‘Barbaresco’ A differed in that tepal colour has a different
shade of dark red-purple (RHS 64A); distal half of leaf
recurved; leaf cross-section angled; colour at the base of the
main vein red-purple; pollen colour orange; stigma colour
green. ‘Stargazer’ differed in that main colour of inner side
of inner tepal ca. RHS 60B-C; tepal margin colour white;
style colour yellow. Seed and pollen parents are noncommercial
breeding lines, therefore, were excluded. No
other varieties of common knowledge have been identified
by the qualified person to have floral characteristics
identical to ‘Corso’.
Comparative Trial The description is based on UPOV
Report of Technical Examination, CPRO-DLO,
Wageningen, The Netherlands, Reference number LEL
1580, and confirmed from local examination. Location:
local DUS trial conducted at Silvan, VIC in an
environmentally controlled glasshouse during summer
period 2001-2. Conditions: cool stored bulbs planted into
trays 40 by 60 cm in a pinebark based potting mix 15-18 cm
deep. 15 bulbs per tray and each tray replicated. Plants
spaced to express their true growth characteristics. Growth
was vigorous, free of stress and plants maintained under
sound cultural procedures. Measurements: observations
made at random from within the plant population.

RHS 68B (RHS 70C), main colour of outer side of
inner tepal red-purple between RHS 68B and RHS 68C
(RHS 70C), main colour of inner side of outer tepal redpurple
RHS 68B (RHS 70C), type of colouration of inner
side of inner tepal single coloured, (colour distribution
uniform), colour of nectar furrow green, position of stigma
in relation to anthers above. Tepal: spots on inner side
present, number of spots on inner side medium, size of
spotted area on inner side medium to large, spots on
papillae present, colour at the base of main vein yellow,
texture of inner side papillose, undulation of margin

flowering: early to medium. (Note: values within
parenthesis are from local observations. All RHS colour
chart numbers used in local observation refer to 1986
edition.)
Origin and Breeding Controlled pollination: seed parent
“unnamed seedling” x pollen parent “unnamed seedling” in
a planned breeding program in Rijnsburg, The Netherlands.
Both parents are non-commercial proprietary breeding lines
within breeder’s private collection. Selection criteria: large
vertical and horizontal flowers suitable for cut flower
production, productive under low light and low temperature
conditions. Propagation: ‘Genova’ proved stable through
numerous generations of scale/bulb and tissue-culture
propagation. Breeder: Cees A. van der Voort, Rijnsburg. The
Netherlands.
Choice of Comparators The grouping characteristic used
in identifying the most similar varieties of common
knowledge was – Flower: main colour of inner side of inner
tepal red-purple. Based of this grouping characteristic
‘Lombardia’ A , ‘Acapulco’ A and ‘Stargazer’ were selected
as comparator varieties. ‘Lombardia’ A differed in that tepal
colour has a different shade of dark red-purple (RHS 65A-
C); nectar furrow colour green over yellow; and colour of
base of main vein inner side orange pink. ‘Acapulco’ A
differed in that tepal colour has another shade of red-purple
(RHS 63B-C); stigma colour dark purple. ‘Stargazer’
differed in that main colour of inner side of inner tepal ca.
RHS 60B-C, tepal margin colour white; style colour yellow.
Seed and pollen parents are non-commercial breeding lines,
therefore, were excluded. No other varieties of common
knowledge have been identified by the qualified person to
have floral characteristics identical to ‘Genova’.
