Applicant: Vletter & Den Haan Beheer B.V., Rijnsburg, The Netherlands. Agent: Watermark – Patent & Trademark Attorneys, Hawthorn, VIC. Characteristics (Figure 10) Plant: height medium. Stem: (mean length 83cm sd 6.9), anthocyanin colouration in middle third of stem present, distribution of anthocyanin colouration speckled and striped, number of leaves on middle third of stem few to medium. Leaf: arrangement alternate, level of leaf tip compared to point of attachment on stem above, distal part straight, length medium to long (mean 149mm sd 16.7), width medium to broad (mean 26.2mm sd.3.0), glossiness of upper surface weak to medium, cross section flat. Inflorescence: type racemose, number of flowers few, pubescence very weak to weak. Flower: type single, attitude of longitudinal axis erect to horizontal, length longest outer tepal medium (mean 141mm sd 5.0), width of widest outer tepal medium to broad (mean 48.6mm sd 3.6), main colour of inner side of inner tepal red-purple RHS 57C (ca. RHS 70C), main colour of outer side of inner tepal red-purple RHS 67D (ca. RHS 70C), main colour of inner side of outer tepal redpurple RHS 57C (ca. RHS 70C), type of colouration of inner side of inner tepal bi-coloured, colour distribution lighter towards base, secondary colour yellow RHS 12B, secondary flower colour along margins absent, secondary colour on basal half present, 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 the main vein yellow, texture of inner side papillose, undulation of margin medium to strong, type of undulation of margin fine and coarse, recurved area distal part only, degree of recurving weak to medium. Stamen: length medium, main colour of filament yellow, anther colour reddish-brown. Pollen: colour orange-brown. Style: main colour green. Stigma: colour greyish-purple. Time of 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: ‘Corso’ proved stable through numerous generations of scale/bulb and tissue-culture propagation. Breeder: Cees A. van der Voort, Rijnsburg. The Netherlands. 38
DESCRIPTIONS PLANT VARIETIES JOURNAL 2002 VOL 15 NO. 2 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.

Applicant: Vletter & Den Haan Beheer B.V., Rijnsburg, The Netherlands. Agent: Watermark – Patent & Trademark Attorneys, Hawthorn, VIC. Characteristics (Figure 11) Plant: height medium. Stem: (length mean 65.4cm sd 0.7), anthocyanin colouration in middle third of stem absent (present as speckles and stripes), number of leaves on middle third of stem few to medium. Leaf: arrangement alternate, level of leaf tip compared to point of attachment on stem above, distal part straight, length medium (mean 134.6mm sd 8.2), width medium to broad (mean 27.2mm sd 1.3), glossiness of upper surface weak, cross section flat. Inflorescence: type racemose, number of flowers few, pubescence absent to weak.

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 medium, type of undulation of margin fine and coarse, recurved area distal part only, degree of recurving medium to strong. Stamen: length medium, main colour of filament green, anther colour orange. Pollen: colour reddish-brown. Style: main colour green. Stigma: colour grey. Time of flowering: early to medium.

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’.
