USPP36150P2 - Begonia plant named ‘KERBESPIPPLE’ - Google Patents

Abstract

A new and distinct cultivar of Begonia tuberhybrida plant named ‘KERBESPIPPLE’ is disclosed, characterized by large, fragrant, double white flowers with a pink flush. Plants are mounding to semi-trailing, free-flowering, with excellent garden performance. The new variety is a Begonia, normally used as an ornamental garden or container plant.

Description

Latin name of the genus and species: Begonia tuberhybrida.

Variety denomination: ‘KERBESPIPPLE’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of a planned breeding program. The new variety originated as the result of a crossing performed during September of 2015 of Begonia ‘Fragrant Blush’(unpatented) with the pollen parent, Begonia tuberhybrida ‘15-501-7’(unpatented). The selection of the new variety was made in June 2016, by the inventor at a research greenhouse located in Cambridge, UK.

Asexual reproduction of the new cultivar ‘KERBESPIPPLE’ was first performed at a research greenhouse located in Cambridge, UK by terminal vegetative cuttings during October 2016. ‘KERBESPIPPLE’ has since produced several generations by vegetative cuttings and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘KERBESPIPPLE’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KERBESPIPPLE.’ These characteristics in combination distinguish ‘KERBESPIPPLE’ as a new and distinct Begonia tuberhybrida cultivar:

• • 1. Large double flowers.
  • 2. Fragrant flowers.
  • 3. Free-flowering.
  • 4. Excellent garden performance.
  • 5. White flowers with a flush of pink.

PARENT COMPARISONS

Plants of the new cultivar ‘KERBESPIPPLE’ are similar to plants of the seed parent variety in most horticultural characteristics. However, plants of the new cultivar ‘KERBESPIPPLE’ differ in the following:

• • 1. Flowers of the new variety are fragrant, while flowers of the seed parent have no fragrance.
  • 2. Flowers of the new variety are double, while flowers of the seed parent are semi-double.
  • 3. Growth habit of the new variety is mounding to semi-trailing, while the growth habit of the seed parent is upright.

Plants of the new cultivar ‘KERBESPIPPLE’ are similar to plants of the pollen parent variety in most horticultural characteristics. However, plants of the new cultivar ‘KERBESPIPPLE’ differ in the following:

• • 1. Plants of the new variety are not as free-flowering as plants of the pollen parent.
  • 2. Plants of the new variety produce fewer branches than plants of the pollen parent.
  • 3. Plants of the new variety are less vigorous than plants of the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KERBESPIPPLE’ are similar to plants of the commercial variety, Begonia ‘Kerbespicit’, U.S. Plant Pat. No. 29,308, in most horticultural characteristics. However, plants of the new cultivar ‘KERBESPIPPLE’ differ in the following:

• • 1. Flowers of the new variety are larger than flowers of this comparator.
  • 2. Flower color of the new variety is white with a pink flush, while the flower color of this comparator is yellow.
  • 3. Plants of the new variety branch more abundantly than plants of this comparator.
  • 4. Plants of the new variety are less compact than plants of this comparator.
  • 5. Flower habit of the new variety is more pendulous than the flower habit of this comparator.
  • 6. The new variety produces more flowers than this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
