plant named ‘Yamina’

Abstract

A new cultivar of Begonia boliviensis named ‘YAMINA’, characterized by its large single bright red flowers, its compact, freely branched and pendulant plant habit, and its good tolerance to wind and rain when grown as a bedding plant in open ground. ‘YAMINA’ has been observed to be mildew free under the conditions grown to date.

Description

Botanical classification: Begonia boliviensis.

Cultivar designation: ‘YAMINA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia boliviensis ‘YAMINA’ and will be referred to hereafter by its cultivar name, ‘YAMINA’.

The new cultivar was derived from a controlled breeding program conducted by the inventor at his nursery in Congleton, Cheshire, United Kingdom. The overall purpose of the breeding program is to make selections of Begonia plants with compact plant habits suitable for container use combined with superior flower performance and productive stock plants for propagation. ‘YAMINA’ was selected in the Inventor's greenhouse in 2006 as a single unique plant from amongst the seedlings derived from a cross made between a proprietary plant used in the Inventor's breeding program (not patented) as the female parent and ‘YABOS’ (U.S. Plant Pat. No. 20,093) as the male parent.

Asexual reproduction of the new cultivar was first accomplished by terminal stem cuttings in Congleton, Cheshire, United Kingdom in 2007 by the Inventor. It has been determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar, which in combination distinguish ‘YAMINA’ as a new and distinct cultivar of Begonia.

• • 1. ‘YAMINA’ exhibits a compact, pendulous plant habit.
  • 2. ‘YAMINA’ readily produces side shoots.
  • 3. ‘YAMINA’ exhibits large, single bright red flowers.
  • 4. ‘YAMINA’ has been observed to be mildew free under the conditions grown to date.
  • 5. ‘YAMINA’ has shown to be well suited for use as a bedding plant as it is able to withstand rain and wind when planted in open ground.

In comparison to its parents plants; ‘YAMINA’ differs in having a more compact plant habit, and by exhibiting a greater resistance to powdery mildew to either parent. In addition, ‘YABOS’ has smaller leaves, smaller flowers and flowers that are paler red in color. ‘YAMINA’ can be most closely compared to the cultivar ‘YASPED’ (U.S. Plant patent application Ser. No. 12/657641). ‘YASPED’ differs from ‘YAMINA’ in having flowers that are slightly larger and paler in color with tepals that are longer and narrower. ‘YAMINA’ can also be compared to cultivars from the same breeding program. ‘Yagance’ (U.S. Plant Pat. No. 19,817) differs most significantly from ‘YAMINA’ in having bicolor pink and white flowers and ‘Yamance’ (U.S. Plant Pat. No. 19,777) differs most significantly from ‘YAMINA’ in having flowers that are pink in color.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Begonia. The photographs were taken of plants approximately 6 months in age as grown in 4.5-inch containers under greenhouse conditions under ambient light in the United Kingdom.

The photograph in FIG. 1 was taken in Congelton, United Kingdom and provides a side view of ‘YAMINA’ in bloom (a basket with two 4.5-inch containers).

The photograph in FIG. 2 was taken in Warwickshire, United Kingdom and depicts a bed of ‘YAMINA’ after a severe thunderstorm with high winds.

The photographs in FIG. 3 and FIG. 4 were taken in Liss, United Kingdom.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘YAMINA’. The photograph in FIG. 3 provides a close-up view of a leaf of ‘YAMINA’. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Begonia.
