Abstract

‘Dozantoky’ is a new variety of calla lily plant having reddish purple colored spathes that produces 5-10 inflorescences per 16-18 cm tuber. The flower stems are about 22-25 cm in height. The leaves are deep green with maculations present and a smooth texture.

Description

Botanical classification: Zantedeschia sprengeri.
Varietal denomination: ‘Dozantoky’.
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 ‘Dozantoky’. ‘Dozantoky’ 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 seedling Z061138-9104 (female parent, unpatented) with Zantedeschia sprengeri variety ‘Zazu’ (male parent, U.S. Plant Pat. No. 28,164). ‘Dozantoky’ 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 ‘Dozantoky’ 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, 4th 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 ‘Dozantoky’ which, in combination, distinguish this calla lily as a new and distinct cultivar:
    • 1. Medium reddish purple colored spathes with a violet colored throat spot;
    • 2. Deep green colored leaves; and
    • 3. Few to an average number leaf maculations present.
The new variety is similar to its female parent in the following traits: spathe and stem color, spathe width, weak flower curve, and the presence of leaf maculations. However, ‘Dozantoky’ exhibits a shorter spathe length and a longer spadix length than its female parent. Further, its female parent does not have a spathe throat spot and has oval shaped leaves. The new variety is similar to its male parent in the following traits: violet colored spathe throat spot, spathe width, spadix length, lanceolate leaf shape, and the presence of leaf maculations. However, ‘Dozantoky’ exhibits a shorter spathe length and a later flowering time than its male parent. Further, its male parent h.as pink colored spathes and green stems.
When compared to calla lily plant named ‘Samur’ (unpatented—abandoned U.S. Plant patent application Ser. No. 13/374,316), ‘Samur’ has an upper surface spathe color from Red-Purple Group RHS 68B to 68D, whereas the upper surface spathe color of ‘Dozantoky’ is from Red-Purple Group RHS 59B to 59C.
