Portulaca cultivar 'DPORMPZGL'

Abstract

The invention relates to the field of Portulaca oleracea, specifically, the variety designated ‘DPORMPZGL’. The variety ‘DPORMPZGL’ is characterized by its controlled, semi-trailing plant habit, with free branching and vivid yellow flowers. The present invention relates to plant parts, including cells and any propagative material of the new variety ‘DPORMPZGL’, and use of any of the plant parts for reproducing the new variety ‘DPORMPZGL’. The present invention relates to methods using any plant parts of ‘DPORMPZGL’ for the purpose of deriving additional new Portulaca varieties. The present invention relates to seed, plants and plant parts produced by crossing ‘DPORMPZGL’ with any other Portulaca variety or other plant. The present invention also relates to methods to produce new varieties of Portulaca oleracea using the variety ‘DPORMPZGL’ and applying plant breeding techniques.

BRIEF DESCRIPTION OF THE FIGURES

[0034] The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawings will be provided by the Office upon request and payment of the necessary fees.

[0035] The accompanying photographs in FIGS. 1 and 2 illustrate the overall appearance of the new Portulaca oleracea referred to as ‘DPORMPZGL’. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describes the color of ‘DPORMPZGL’.

[0036] FIG. 1 illustrates in full color a typical plant of ‘DPORMPZGL’ at about 8 weeks of age, grown in a 13 cm pot.

[0037] FIG. 2 illustrates in full color a close-up view of a typical flower of the new variety.

[0038] The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
