ABSTRACT:
LATIN NAME OF GENUS AND SPECIES
Rosa hybrida.
VARIETY DENOMINATION
‘JACergma’.
SUMMARY OF THE INVENTION
The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing the variety ‘POULman’, U.S. Plant Pat. No. 6,264, with the variety ‘JACbor’. U.S. Plant Pat. No. 6,668.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a new rose variety having the bright red flower, fairly compact growth and dark green leathery foliage of the female parent combined with the well formed flowers, continuous bloom and vigorous upright growth of the male parent.
BRIEF SUMMARY OF THE INVENTION
The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:
1. Bright red flowers;
2. Dark green, leathery foliage;
3. Vigorous, upright growth;
4. Long lasting cut flowers; and
5. High centered blooms.
Asexual reproduction of this new variety by budding on ‘Dr. Huey’ (unpatented) understock, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
COMPARISON WITH PARENTS
The female parent, ‘POULman’, has larger flowers with more petals than JACergma. The male parent, ‘JACbor’, has larger flowers of orange color but shorter vase life.
COMPARISON WITH SIMILAR VARIETY
‘JACergma’ differs from ‘JAColber’ in that ‘JACergma’ has a more compact plant habit, brighter red flowers on shorter stems and has greater disease resistance.
