USPP19450P3 - Nolana hybrida cultivar ‘Lorma Blanca’ - Google Patents

Abstract

A new and distinct cultivar of Nolana plant named ‘Loma Blanca’, characterized by numerous single flowers that are white in color with a dark purple veined center; dark purple anthers and pollen grains, freely branching growth habit, no fruit set from self pollination, and good performance in the garden and as a hanging basket.

Description

Botanical designation: Nolana hybrida.

Variety denomination: ‘Loma Blanca’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Nolana plant, botanically known as a Nolana artificial hybrid, and hereinafter referred to by the cultivar name ‘Loma Blanca’.

The new Nolana is a product of a planned breeding program conducted by the Inventor in Durham, N.H. The objective of the breeding program is to create new compact Nolana plants with attractive flowers, profuse flowering and reduced fruit set.

The new ‘Loma Blanca’ originated from seed collected from open pollination of a proprietary selection of Nolana identified with code number UNH N2-46-2 (NOL5), not patented. Seed was collected from a greenhouse-grown plant on Jan. 17, 2003 and sown on Nov. 24, 2003. From the progeny, a single plant N5-OP-24 was selected in Durham, N.H., USA, on the basis of its profuse flowering, compact growth habit and attractive flowers.

Asexual reproduction of the new cultivar by terminal vegetative cuttings since April, 2004, taken in Durham, N.H. has shown that the unique features of this new Nolana are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

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

• • 1. Numerous single flowers that are white in color with a dark purple veined center.
  • 2. Dark purple anthers and pollen grains.
  • 3. Freely branching growth habit.
  • 4. No fruit set from self pollination.
  • 5. Good performance in the garden and as a hanging basket.

In side-by-side comparisons conducted in Durham, N.H., plants of the new Nolana differed from plants of the parent selection, in the following characteristics:

• • 1. Flowers of plants of the new Nolana were white with dark purple center while flowers on the parent selection were light blue with white center.
  • 2. Flowers of plants of the new Nolana had dark purple anthers and pollen grains while flowers on the parent selection were white.
  • 3. Plants on the new Nolana were less pubescent than plants of the parent selection.

Plants of the new Nolana can be compared to plants of Nolana cultivar ‘Nolgold’ (a.k.a. ‘Blue Eyes’) U.S. Plant Pat. No. 14,141. In side-by-side comparisons conducted in Durham, N.H., plants of the new Nolana differed from plants of ‘Nolgold’ in the following characteristics:

• • 1. Plants of the new Nolana had white flowers with purple center while flowers on the cultivar ‘Nolgold’ were blue violet and white bicolored.
  • 2. Flowers of plants of the new Nolana had dark purple anthers and pollen grains while flowers on the cultivar ‘Nolgold’ were white.
  • 3. Plants of the new Nolana had smaller flowers than plants of the cultivar ‘Nolgold’.
  • 4. Plants of the new Nolana had shorter internodes than plants of the cultivar ‘Nolgold’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 Nolana.

One photograph comprises a side perspective view of one typical 22-cm container of ‘Loma Blanca’ with three plants.

The other photograph is a close-up view of typical flowers and leaves of ‘Loma Blanca’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Durham, N.H., in a heated greenhouse with 21° C. day/18° C. night set points. After planting rooted cuttings, plants were grown for about four months in 20-cm containers with three plants per container. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Color was evaluated under indirect, natural light.
