The present invention relates to plants of the genus Catharanthus containing a broad spectrum genetic resistance to Phytophthora. In particular, the present invention relates to a Catharanthus roseus plant containing a broad spectrum genetic resistance to P. nicotianae.

A method for regulating plant architecture includes applying a composition containing γ-Aminobutyric acid (GABA), glutamic acid and choline chloride to a plant. The composition for regulating plant architecture is also provided.

The invention provides seeds and plants of Catharanthus hybrid ‘PAS1192826’ and the parent lines thereof. The invention thus relates to the plants, seeds, plant parts, and tissue cultures of Catharanthus hybrid ‘PAS1192826’ and the parent lines thereof, and to methods for producing a Catharanthus plant produced by crossing such plants with themselves or with another Catharanthus plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates plants, seeds, plant parts and tissue cultures of Catharanthus hybrid ‘PAS1192826’ and the parent lines thereof comprising introduced beneficial or desirable traits.

Disclosed herein is a new and distinct variety of Catharanthus plant having vigorous, upright plant characteristics, abundant branching, especially basally branching, developed from the base of the plant throughout the growing season, great profusion of single, pale pink flowers, the whole bush remaining in bloom for a considerable period of time and deeply bitten petals, shaped of hastate, incurvated.

A new and distinct cultivar of Catharanthus plant named ‘Suncatfe 43’, characterized by its compact, upright to outwardly spreading and uniformly mounding plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; long flowering period; relatively small star-shaped white-colored flowers; and good garden performance.

A new and distinct cultivar of Catharanthus plant named ‘Suncatfe 185’, characterized by its compact, upright to outwardly spreading and uniformly mounding plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; long flowering period; relatively small star-shaped pink-colored flowers with a distinct red purple-colored eye zone; and good garden performance.

A new and distinct cultivar of Catharanthus plant named ‘Suncatso 23’, characterized by its upright to outwardly spreading and mounding plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; long flowering period; double-type flowers that are purple violet in color; and good garden performance.

The present invention relates to plants of the genus Catharanthus containing a genetic resistance to Phytophthora. In particular, the present invention relates to a Catharanthus roseus plant containing a genetic resistance to the F and S isolates of P. nicotianae.

The invention provides seeds and plants of Catharanthus hybrid ‘PAS1305707’ and the parent lines thereof. The invention thus relates to the plants, seeds, plant parts, and tissue cultures of Catharanthus hybrid ‘PAS1305707’ and the parent lines thereof, and to methods for producing a Catharanthus plant produced by crossing such plants with themselves or with another Catharanthus plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates plants, seeds, plant parts and tissue cultures of Catharanthus hybrid ‘PAS1305707’ and the parent lines thereof comprising introduced beneficial or desirable traits.
