USPP33894P2 - Calla lily plant named ‘Dozanwhiho’ - Google Patents

Abstract

‘Dozanwhiho’ is a new variety of calla lily plant having white colored spathes with a purple/pink throat spot that produces 6-10 inflorescences per 16-18 cm tuber. The flower stems are about 30-40 cm in height. The leaves are brownish green to dark green with maculations present and a smooth texture.

Description

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Dozanwhiho’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of calla lily, botanically known as Zantedeschia sprengeri and hereinafter referred to by the varietal name ‘Dozanwhiho’. ‘Dozanwhiho’ is a product of a planned breeding program, which had the objective of creating Zantedeschia hybrids for pot flower production in a wide range of colors with a classic flower shape. The new cultivar is a seedling selected from the crossing of Zantedeschia sprengeri variety ‘Fangio’ (female parent, U.S. Plant Pat. No. 28,196) with Zantedeschia sprengeri seedling Z050867-9107 (male parent, unpatented). ‘Dozanwhiho’ was selected in 2014 by the inventor in 't Zand, The Netherlands as one flowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Dozanwhiho’ by tissue culture was performed by the inventor in November of 2014 in 't Zand, The Netherlands. Subsequent asexual reproductions by tissue culture at the same location have demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained and reproduced true to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plants at approximately 11 weeks from planting in 14 cm pots in 't Zand, The Netherlands under greenhouse conditions, which approximate those generally used in horticultural practice. Color references are made to The 2001 R.H.S. Colour Chart of The Royal Horticultural Society of London, 4^th Edition, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to be basic characteristics of ‘Dozanwhiho’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

• • 1. Medium white colored spathes with a purple/pink colored throat spot;
  • 2. Dark to brownish green colored leaves; and
  • 3. Medium leaf maculations present.

The new variety is similar to its female parent in the following traits: throat spot presence, strong flower curve, lanceolate leaf shape, and the presence of leaf maculations. However, ‘Dozanwhiho’ exhibits a broader spathe width and longer spathe and spadix length than its female parent. Further, ‘Fangio’ has pink colored spathes, yellow/red spadix color, and red/green stem color. The new variety is similar to its male parent in the following traits: strong flower curve, long spadix length, green stem color, and the presence of leaf maculations. However, ‘Dozanwhiho’ exhibits a lighter spathe color, narrower spathe width, and shorter spathe length than its male parent. Further, its male parent does not exhibit a spathe throat spot and has a purple spadix color.

When compared to calla lily plant named ‘Diva Siberia’ (U.S. Plant Pat. No. 32,492), both varieties exhibit white colored spathes, but ‘Diva Siberia’ is a variety of Zantedeschia aethiopica and does not exhibit a spathe throat spot or leaf maculations.
