USPP32490P3 - Calla lily plant named ‘Diva Himalaya’ - Google Patents

Abstract

‘Diva Himalaya’ is a new variety of calla lily plant having white colored spathes and thin, strong peduncles. The leaves are green with no maculations present.

Description

Botanical classification: Zantedeschia aethiopica.

Varietal denomination: ‘Diva Himalaya’.

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 ‘Diva Himalaya’.

‘Diva Himalaya’ is a product of a planned breeding program and the new cultivar was selected in Santa Cruz, Calif. from the F2 population of the crossing of unpatented Zantedeschia seedling 7043-BK (female parent) with unpatented Zantedeschia seedling 94109-56 (male parent). When compared to its female parent, the blooms of ‘Diva Himalaya’ are more white in color, smaller, and exhibit earlier maturity. Further, the slim, strong flower stems of ‘Diva Himalaya’ are easier to pull at harvest. The leaves of ‘Diva Himalaya’ are smaller and more dense than its female parent. When compared to its male parent, the blooms of ‘Diva Himalaya’ are larger, with a better wrapped and formed spathe. Further, the overall plant size and leaves of ‘Diva Himalaya’ are larger than its male parent.

The new variety was initially asexually reproduced through tissue culture propagation in Santa Cruz, Calif. Asexual reproductions of ‘Diva Himalaya’ have demonstrated that the combination of characteristics as herein disclosed for the new variety are retained and reproduced true to type through successive generations of asexual reproduction.

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 ‘Diva Himalaya’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

• • 1. White colored spathes;
  • 2. No leaf maculations;
  • 3. Early production time;
  • 4. Thin, strong peduncles; and
  • 5. Easy to transport.

Table 1 provides a comparison of ‘Diva Himalaya’ to similar Zantedeschia aethiopica varieties ‘Avalanche’ (unpatented) and ‘Innocence’ (unpatented).
