Miniature rose plant--Meifinaro variety

- The Conard-Pyle Company

A new and distinct variety of rose plant of the Miniature Class is provided having attractive well formed very double blossoms which are neyron pink in coloration. The new variety resulted from the crossing of Meirotego variety with pollen from an unnamed seedling which was formed by crossing the Meilucca and Perla de Montserrat varieties. The new variety has a compact and vigorous growth habit and is well adapted for landscape uses.SUMMARY OF THE INVENTIONThe new and distinct variety of rose plant of the Miniature Class was originated by me by crossing the Meirotego variety (non-patented) with pollen from an unnamed and non-patented variety formed by crossing the Meilucca variety (non-patented) and the Perla de Montserrat variety (non-patented). The parentage of the new variety can be summarized as follows:Meirotego.times.[Meilucca.times.Perla de Montserrat].From this controlled pollination I produced a new and distinct variety of rose plant of the Miniature Class which is distinguished from its parents, as well as from all other varieties of which I am aware. This variety was obtained through the selective study of a large number of distinct plants which resulted from the above cross. A single plant resulting from this cross possessed the characteristics of the presently claimed variety.It was found that the new variety as illustrated herein possesses (a) a compact and vigorous growth habit, (b) bronzed green adult wood, and (c) the abundant and continuous formation of attractive well formed very double blossoms which are neyron pink in coloration.The new variety additionally matures quickly, and forces well. Its propensity to continuously produce well formed beautiful neyron pink blossoms (as described) in profusion is impressive. The blossoms have a long life and the petals tend to drop off cleanly. The new variety is not particularly susceptible to cryptogamic diseases.Extensive testing has confirmed the behavior and characteristics of the new variety. The new variety is particularly suited for growing in parks and gardens.The characteristics and properties of the new variety are strictly transmissible by asexual propagation, e.g. by budding.The rose plant of the new variety has been designated the Meifinaro variety .

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in a color illustration of this character, typical specimens of plant parts of the new variety observed during August and cultivated in a greenhouse at Le Cannet des Maures, Var, France. The rose plants of the new variety were two years of age and were grafted on Rosa indica.

DETAILED DESCRIPTION

The plants described were grown in pots in greenhouses at Le Cannet des Maures, Var, France.

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology preceding the numbered references has been added to designate in common terms, the corresponding colors.
