USPP22643P3 - Begonia plant named ‘HV01B1’ - Google Patents

Abstract

A new and distinct Begonia cultivar named ‘HV01B1’ is disclosed, characterized by its bright green foliage with a notched margin and bright yellow/orange and red flowers. The new cultivar is a Begonia, typically suited for ornamental container use.

Description

Latin name of the genus and species: Begonia elatior.

Variety denomination: ‘HV01B1’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a chance discovery in an existing population of Begonia elatior plants. The new variety originated as a naturally occurring, whole plant mutation of the parent variety, the unpatented commercial variety, Begonia elatior ‘Carnaval.’ The new variety was discovered by the inventor, Jos ten Have, a citizen of the Netherlands, in the Summer of 2004 at a commercial greenhouse in Maasland, the Netherlands.

After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘HV01B1’was first performed in the same commercial greenhouse by vegetative cuttings in the winter of 2004. ‘HV01B1’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘HV01B1’ 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 ‘HV01B1’. These characteristics in combination distinguish ‘HV01B1’ as a new and distinct Begonia cultivar:

• • 1. Bright green foliage.
  • 2. Distinctively notched foliage margins.
  • 3. Distinctive orange-yellow flowers with red margin.
  • 4. Folded, ligulate floret.

PARENTAL COMPARISON

Plants of the new cultivar ‘HV01B1’ are similar to the parent ‘Carnaval’ in most horticultural characteristics. However, ‘HV01B1’ differs in producing foliage with a notched margin not found on ‘Carnaval.’ Additionally, ‘HV01B1’ produces a larger flowers, of a different shape and brighter color than ‘Carnaval.’

COMMERCIAL COMPARISON

Plants of the new cultivar ‘HV01B1’ are best compared to the parent variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘HV01B1’ grown in a greenhouse in Maasland, the Netherlands. This plant is approximately 10 weeks old, shown in a 10 cm pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
