ORIGIN OF THE VARIETY
The rose variety ‘KORtiglo’ / ‘Caramel Antike’ originated from a controlled crossing in a breeding program of two distinct parents during the summer of 1997. The crossing was between following parent roses:

  Seed parent - ‘Gold Glow’, a Hybrid Tea rose by Anthony Perry, 1959.

  Pollen parent - an un-named seedling.

BACKGROUND OF THE VARIETY
The resulting seeds were planted during the following winter. The resulting seedlings were evaluated and exhibited distinctive physical and biological characteristics. The new rose plant was selected as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety was ‘KORtiglo’ / ‘Caramel Antike’.

SUMMARY OF THE VARIETY
The objective of the hybridization for this rose was to create a new and distinct rose plant with unique qualities, such as:

• Uniform growth and flowering;

• Abundant attractive, recurrent flowers;

• Attractive and abundant foliage; and

• Resistance to diseases encountered in landscapes and gardens.

These objectives have been substantially achieved and in that distinguish ‘KORtiglo’ / ‘Caramel Antike’ from all other varieties.

As part of a rose development program, Tim-Hermann Kordes germinated seeds from the aforementioned hybridization and conducted evaluations and observations on the resulting seedlings in a controlled environment in Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibited distinctive physical and biological characteristics. The rose plant ‘KORtiglo’ / ‘Caramel Antike’ was selected in May, 1998 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORtiglo’ / ‘Caramel Antike’ was done by budding to seedling understocks in July, 1998 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.

This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORtiglo’ / ‘Caramel Antike’ reproduces true to type in successive generations of asexual reproduction.

COMPARISON WITH PARENTS
The ‘KORtiglo’ / ‘Caramel Antike’ rose plant may be distinguished from its seed parent, ‘Gold Glow’, by the following combination of characteristics:

•The flower size of ‘KORtiglo’ / ‘Caramel Antike’ is large, while the flower size of ‘Gold Glow’ is medium; and

•the petal count of ‘KORtiglo’ / ‘Caramel Antike’ is very double, while the petal count of ‘Gold Glow’ is semi-double.

‘KORtiglo’ / ‘Caramel Antike’ may be distinguished from its pollen parent, an un-named seedling, by the following combination of characteristics:

•The growth habit of ‘KORtiglo’ / ‘Caramel Antike’ is upright, while the growth habit of the un-named seedling is bushy; and

• ‘KORtiglo’ / ‘Caramel Antike’ exhibits better disease resistance than the un-named seedling.
