Sport (biology)

As a sport to be rung referred to in plants due to somatic mutations (ie mutations in plants growing body and not in the sex cells ) are different from the parent plant. You can clearly differ morphologically from the original plant. By cultivating them as cuttings , new varieties can sometimes be obtained.

Examples

Hostas

Especially with hostas ( Hosta ) such mutations are observed.

Hosta are genetically unstable. It can happen that a hosta forms a shoot that shows a different variegation (leaf pattern) than the mother plant. Such drives are called sports. When such shoots have developed their own roots, they can be separated from the mother plant and cultivated as independent "new hosta". Approx. 40% of all new Hosta varieties are sports known and registered name varieties.

Examples:

H . 'June' is a sport of H . 'Halcyon',
H . 'Striptease' is a sport of H . 'Gold Standard',
H . 'Stained Glass' is a sport of H . 'Guacamole',
H . 'Dreamweaver' sport of H . 'Great Expectations'

Roses

Roses also tend to form sports, some of which are marketed as new varieties or climbing variants. Probably the first sport of a rose was discovered before 1699 when the first moss rose Rosa x centifolia 'Muscosa' emerged from Rosa x centifolia L. The origin "Holland, before 1596", which is often mentioned in the literature, has not been proven and is probably incorrect.

David Austin launched two mutations of his English rose 'Mary Rose', introduced in 1983 - 'Redouté' and 'Winchester Cathedral' in 1992 . The sports of 'Gloria Dei' (Meilland 1939) include a climbing variant discovered in 1949, as well as the varieties 'Kronenbourg' (McGredy 1965), 'Chicago Peace' (Johnston 1962) and 'Lucky Peace' (Gordon 1958).
