USPP32715P3 - Calla lily plant named ‘A405’ - Google Patents

Abstract

‘A405’ is a new variety of calla lily plant having white colored spathes that produces 6-10 inflorescences per 16-18 cm tuber. The flower stems are about 30-40 cm in height. The leaves are green with numerous whitish spots and have a leathery texture.

Description

Botanical classification: Zantedeschia aethiopica.

Varietal denomination: ‘A405’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia aethiopica and hereinafter referred to by the cultivar name ‘A405’.

‘A405’ 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 large, classic flower shape. The breeding program began in 2007, and the new cultivar is a seedling selected from the crossing of Zantedeschia aethiopica seedling A080017-211 (female parent, unpatented) with Zantedeschia aethiopica seedling A090001-3 (male parent, unpatented). ‘A405’ 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 ‘A405’ by tissue culture was performed by the inventor in September 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 grown from 12 to 14 weeks 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 ‘A405’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

• • 1. Compact plant habit;
  • 2. Numerous leaf maculations; and
  • 3. High inflorescence production.

Table 1 provides a comparison of ‘A405’ to its parents, as well as Zantedeschia aethiopica variety ‘Colombe de la Paix’ (unpatented).
