Gerbera with multi-petalled and globular shaped inflorescences

摘要

New, distinct and stable Gerbera jamesonii cultivars with multi-petalled and globular-shaped inflorescences are disclosed. The new Gerbera jamesonii cultivars produce one or more inflorescences with i) at least 320, to about 550, full or partial outer petals (ray florets) per inflorescence, ii) at least 150, to about 300, full or partial inner petals (disc florets) per inflorescence, and iii) at least 520, to about 800, full or partial total petals (total florets) per inflorescence.. Multi-petalled-flowering and globular-shaped Gerbera jamesonii cultivars are disclosed in which substantially all the inflorescences produce i) at least 320, to about 550, full or partial outer petals (ray florets) per inflorescence, ii) at least 150, to about 300, full or partial inner petals (disc florets) per inflorescence, and iii) at least 520, to about 800, full or partial total petals (total florets) per inflorescence. The multi-petalled-type and globular-shaped inflorescence characteristic has been successfully bred into single-type (at least 50, to about 75, full or partial outer petals (ray florets) per inflorescence) and semi-double-type (at least 130, to about 170, full or partial outer petals (ray florets) per inflorescence) and double-type (at least 250, to about 270, full or partial outer petals (ray florets) per inflorescence) and double-multi-type (at least 270, to about 320, full or partial outer petals (ray florets) per inflorescence) Gerbera cultivars. The multi-petalled-type and globular-shaped inflorescence characteristic has been combined with many desirable Gerbera jamesonii traits, such as inflorescence color, inflorescence quality, stem quality, inflorescence productivity and vase life. Methods for the breeding of the multi-petalled-type and globular shaped inflorescence characteristic into diverse single-type or semi-double-type or double-type or double-multi-type Gerbera jamesonii genetic backgrounds, as well as, methods for increasing the degree of multi-petalledness per inflorescence or plant are disclosed.
