Location Pruistelle Rethmar, Germany. Local observation at Portland,
VIC
Descriptor TG/11/7.
Period 2003.
Conditions The comparative study was conducted at Portland (Latitude
38.15S, Longitude 141.37E), VIC. The roses were maintained
in the open and grown in a well structured loamy clay soil.
Sound farm management practices ensured the plants grew to
their full potential with minimum stress and under high health
conditions. ‘Kormamtiza’ was budded in early summer onto
well established 10 month-old Rosa multiflora rootstock.
Examination was conducted in mid autumn 2008 on one and
two year old budded plants growing in double rows along
with other varieties of Kordes roses.
Trial Design Observations and measurements were taken from a minimum
of ten plants, selected at random in mid autumn.
Measurements Measurements made on terminal leaflet on the first fiveleaflet
leaf down the flower stem; flower diameter made when
flower first fully open, and sepal length excludes the terminal
leafy extension if present.

Origin and Breeding
Controlled pollination: seed parent unnamed seedling (Roseromatica x Heckenfeuer),
crossed with pollen parent ‘Taneitber’ in May 1993. Hips produced remained on bush
until Oct (autumn) when harvested and shelled. Seeds planted under controlled
greenhouse conditions: germination commenced in Feb 1994, and the seedlings first
bloomed in May (Northern Hemisphere). From this seedling population, the best
seedlings were selected for further trials. Budding eyes were taken in Jul 1994 and
budded to understock of R. canina and planted in the open. From these the seedling,
now known as ‘Kormamtiza’, was selected for further testing until 2002, and first
sales were made in 2003. This new variety was multiplied in number by vegetative
propagation, and has flowered for over five generations and appears to be genetically
stable. Selection criteria: improved garden rose variety. Breeding directed by William
Kordes, of W. Kordes’ Sohne Rosenschulen GMBH & Co KG,
Sparrieshoop,Germany.
