USPP29308P2 - Begonia plant named ‘KERBESPICIT’ - Google Patents

Abstract

A new and distinct Begonia tuberhybrida cultivar named ‘KERBESPICIT’ is disclosed, characterized by cream yellow colored, strongly fragrant flowers. Plants are mounded to semi-upright, free-branching with excellent weather tolerance. The new variety is a Begonia, and is normally used as an ornamental garden or container plant.

Description

Latin name of the genus and species: Begonia tuberhybrida.

Variety denomination: ‘KERBESPICIT’.

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 2009 of Begonia ‘Fragrant Blush’(unpatented) with the pollen parent, Begonia tuberhybrida ‘Helene Harms’(unpatented). The selection of the new variety was made in July 2010, by the inventor at a research greenhouse located in Cambridge, UK.

Asexual reproduction of the new cultivar ‘KERBESPICIT’ was first performed at a research greenhouse located in Cambridge, UK by terminal vegetative cuttings during February 2011. ‘KERBESPICIT’ 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 ‘KERBESPICIT’ 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 ‘KERBESPICIT.’ These characteristics in combination distinguish ‘KERBESPICIT’ as a new and distinct Begonia tuberhybrida cultivar:

• 1. Mounding to semi-trailing plant habit.
• 2. Strongly fragrant flowers.
• 3. Cream Yellow flower color, without pink blush.
• 4. Free branching.
• 5. Medium flower size.
• 6. Excellent weather tolerance
• 7. Suitability for pot sizes 12 cm and larger.
• 8. Flowers upwardly or outwardly facing.

PARENT COMPARISON

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

• 1. Flowers of the new variety are cream yellow, flowers of the seed parent are cream with pink blush.
• 2. Plants of the new variety have a mounding to semi-trailing habit, plants of the seed parent are more upright.
• 3. Stems of the new variety are smaller in diameter than the seed parent.
• 4. Plants of the new variety branch more abundantly than the seed parent.

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

• 1. Flowers of the new variety are larger than flowers of the pollen parent.
• 2. Flowers of the new variety are strongly fragrant, flowers of the pollen parent are unscented.
• 3. Flower color of the new variety is a much lighter yellow.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KERBESPICIT’ are similar to plants of the commercial variety, Begonia ‘Fragrant Falls Lemon Fizz’, in most horticultural characteristics. However, plants of the new cultivar ‘KERBESPICIT’ differ in the following:

• 1. Flowers of the new variety are a lighter yellow color.
• 2. Flowers of the new variety are smaller than those of this comparator.
• 3. Plants of the new variety are more free branching than this comparator.
• 4. Plants of the new variety are mounding to semi-upright, plants of this comparator are upright, then lodging over with age.

Plants of the new cultivar ‘KERBESPICIT’ are similar to plants of the commercial variety, Begonia ‘77KL Sunrise’, U.S. Plant Pat. No. 12,808, in most horticultural characteristics. However, plants of the new cultivar ‘KERBESPICIT’ differ in the following:

• 1. Flowers of the new variety are a lighter yellow color.
• 2. Flowers of the new variety are smaller than those of this comparator.
• 3. Plants of the new variety are more free branching than this comparator.
• 4. Plants of the new variety are mounding to semi-upright, plants of this comparator are upright, then lodging over with age.
• 5. Flowers of the new variety are upwardly or outwardly facing, flowers of the comparator are pendulous and downward facing.
