Gypsophila named ‘Dangypurna’

Abstract

A new and distinct Gypsophila plant named ‘Dangypurna’ characterized by having white semi-double flowers (in winter) to double flowers (in summer), depending on growing conditions, globular shape, 8-10 mm corolla diameter; conic inflorescence form; 90-100 cm plant height, 50-60 cm plant width, erect, branching from plant base; suitable as a commercial product for cut flowers; and vigorous growth habit.

Description

Latin name of the genus and species of the plant claimed: Gypsophila paniculata.

Variety denomination: Dangypurna.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gypsophila plant, botanically known as Gypsophila paniculata, hereinafter referred to by the cultivar name ‘Dangypurna’.

The new cultivar was derived from an open pollination with a proprietary female cultivar and unknown male parent made in a controlled breeding program in Mishmar Hashiva, Israel. The female parent is a proprietary unpatented cultivar from a hybrid line identified as ‘1102’. The male parent is open pollination. ‘Dangypurna’ was discovered and selected by the inventor, Gabriel Danziger, as a flowering plant within the progeny of the open pollination in a controlled environment in Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar by removing a cutting from the initial plant was first performed in December, 1999 in Mishmar Hashiva, Israel and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Dangypurna’ which in combination distinguish this Gypsophila as a new and distinct cultivar:

1. White semi-double flowers (in winter) to double flowers (in summer), depending on growing conditions; globular shape, 8-10 mm corolla diameter;

2. Conic inflorescence form;

3. 90-100 cm plant height, 50-60 cm plant width, erect, branching from plant base;

4. Suitable as a commercial product for cut flowers; and

5. Vigorous growth habit.

‘Dangypurna’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Mishmar Hashiva, Israel under conditions which closely approximate those generally used in commercial practice.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Dangypurna’ is the Gysophila cultivar ‘Dangypflash’ (U.S. Plant Pat. No. 12,422). In comparison to ‘Dangypflash’, ‘Dangypurna’ has a higher stem yield, more upright growth habit and more symmetrical flowers.

The following is a comparison chart between ‘Dangypurna’ and the female parental cultivar.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the new cultivar at 12 weeks, as grown in Mishmar Hashiva, Israel under conditions which closely approximate those generally used in commercial practice. Regular cultural practices common for gypsophila in commercial fields were applied. Avoid excess GA or lighting. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately noon in Mishmar Hashiva, Israel.
