USPP23512P3 - Cordyline plant named ‘CORBZR01’ - Google Patents

Abstract

A new and distinct Cordyline hybrid named ‘CORBZR01’ is disclosed, characterized by pink striped foliage color, and distinctive clumping growth habit. Plants are compact and bushy, forming weeping foliage. The new cultivar is a Cordyline typically suited for ornamental container and landscape use.

Description

Latin name of the genus and species: Cordyline hybrid.

Variety denomination: ‘CORBZR01’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a chance discovery in a commercial laboratory in Israel. The inventor, Issachar Benzur, a citizen of Israel, discovered the new variety as a single whole plant, chemically induced mutation of the parent variety, Cordyline hybrid ‘JURred’ U.S. Plant Pat. No. 14,224. The known chemical mutagen used was 10 ppm of 6 Benziylaminopurine. The discovery was made in March of 2007.

After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘CORBZR01’ was first performed in the same commercial laboratory by tissue culture in July 2007. In January 2008 the final, stable clone referred to as ‘CORBZR01’ was selected. ‘CORBZR01’ has since produced at least 10 generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘CORBZR01’ 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 ‘CORBZR01.’ These characteristics in combination distinguish ‘CORBZR01’ as a new and distinct Cordyline cultivar:

• • 1. Pink striped foliage color
  • 2. Compact, bushy growth habit.
  • 3. Cascading, weeping foliage.
  • 4. Clumping from the base.

PARENTAL COMPARISON

Plants of the new cultivar ‘CORBZR01’ are similar to the parent, ‘JurRed’ in most horticultural characteristics. However, ‘CORBZR01’ differs in having pink striped foliage. Additionally, the new variety produces plants that are shorter and narrower than the parent variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘CORBZR01’ are best compared to the parent variety, due to the unique plant form.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘CORBZR01’ grown in a greenhouse in Watsonville, Calif. This plant is approximately 12 to 18 months old, grown in a 1 gallon 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.

DETAILED BOTANICAL DESCRIPTION
