Appl. No.:

08/555755

International Classification:

A01H 500

US Classification:

800311, 800283, 800286, 800294

Abstract:

A process for commercially propagating plants by tissue culture in such a way as both to conserve desired plant morphology and to transform the plant with respect to one or more desired genes. The method includes the steps of (a) creating an Agrobacterium vector containing the gene sequence desired to be transferred to the propagated plant, preferably together with a marker gene; (b) taking one or more petiole explants from a mother plant and inoculating them with the Agrobacterium vector; (c) conducting callus formation in the petiole sections in culture, in the dark; and (d) culturing the resulting callus in growth medium containing a benzylamino growth regulator such as benzylaminopurine or, most preferably, benzylaminopurineriboside. Additional optional growth regulators including auxins and cytokinins (indole butyric acid, benzylamine, benzyladenine, benzylaminopurine, alpha naphthylacetic acid and others known in the art) may also be present. Preferably, the petiole tissue is taken from and the Agrobacterium vector contains an antisense gene for ACC synthase or ACC oxidase to prevent ACC synthase or ACC oxidase expression and, in turn, the ethylene formation for which these enzymes are precursors.

Appl. No.:

8/347583

Inventors:

Eleanor Stoots - Connellsville PA

Assignee:

Oglevee, Ltd. - Connellsville PA

International Classification:

A01H 500

US Classification:

Plt 8712

Abstract:

The new cultivar is early flowering and maintains a controlled growth habit. It is also free flowering. It is very heat tolerant, recovers quickly after wet weather conditions and still exhibits a neat mound habit. The bloom color is a bright red on a dark green foliage.

International Classification:

US Classification:

43524045

Abstract:

A process for propagating Pelargonium x domesticum varieties by tissue culture propagation of petiole sections taken from a mother plant. In addition to tissue culture propagation steps and growth media constituents which are known in the art, an essential step of the preferred embodiment of the invention includes the conducting of callus formation by initial culturing of the petiole section in the dark. In all embodiments of the invention, however, it is believed that the effectiveness of the present process is attributable at least in part to the presence in the culture medium of a growth regulator selected from the group consisting of amino or benzyl-glucosides and amino- or benzyl-glycosides or any other composition chemically equivalent to the exemplary regulator benzylamino riboside.

Inventors:

Eleanor Stoots - Connellsville PA

Assignee:

Oglevee, Ltd. - Connellsville PA

International Classification:

A01H 500

US Classification:

Plt 8712

Abstract:

The new cultivar is characterized by the rich rose pink colored bloom which is very slow to shatter and has strong tolerance to heat. The short internodes and low basal branching results in a variety that is both a good cutting producer and an excellent outdoor garden cultivar.
