USPP19549P3 - Aglaonema plant named ‘TWYAG0060’ - Google Patents

Abstract

A new Aglaonema plant particularly distinguished by having a very dense leafy, compact and upright highly branched growth habit, being intermediate in stature and very vigorous and producing axillary branches and numerous leaves is disclosed.

Description

Genus and species: Aglaonema hybrid.

Variety denomination: ‘TWYAG0060’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Aglaonema, botanically known as Aglaonema hybrid, and hereinafter referred to by the cultivar name ‘TWYAG0060’. The new cultivar originated from a hybridization made in W. Java, Indonesia. The cross was made in 2002 between the female parent, an unnamed individual plant of A. rotundum (unpatented) and the male parent, an unnamed individual plant of A. commutatum (unpatented).

The new cultivar was created in W. Java, Indonesia and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Apopka, Fla. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Apopka, Fla.

• • 1. Intermediate in stature;
  • 2. Very dense leafy, compact and upright, highly branched growth habit;
  • 3. Very vigorous; and
  • 4. Produces axillary branches and numerous leaves.

DESCRIPTION OF PHOTOGRAPH

This new Aglaonema plant is illustrated by the accompanying photograph which shows the upper and lower surface of a mature leaf of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘TWYAG0060’. The data which define these characteristics were collected from asexual reproductions carried out in Apopka, Fla. The plant history was taken on 16-month old plants started from a single 4-leaf rooted cutting, still in a vegetative state and grown in Apopka, Fla. Rooted cuttings were planted in 20-cm pots and grown in a greenhouse in May 2006. The plants were pinched twice. Color readings were taken under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘TWYAG0060’ differs from the female parent, an unnamed individual plant of A. rotundum (unpatented), by having a more compact growth habit and more branching than the female parent. Additionally, ‘TWYAG0060’ has elliptic to ovate leaves with pink and yellow-green blotches while the female parent has broadly ovate leaves lacking either pink or yellow-green blotches.

‘TWYAG0060’ differs from the male parent, an unnamed individual plant of A. commutatum (unpatented) by having a more compact growth habit and more branching than the male parent. Additionally, ‘TWYAG0060’ has very colorful leaves while the male parent has pale green leaves with lateral gray-green markings.

‘TWYAG0060’ differs from the commercial cultivar ‘Red Gold’ (unpatented), in that ‘TWYAG0060’ has a shorter and more compact growth habit than ‘Red Gold’. In addition, ‘TWYAG0060’ has darker green leaves with maroon undersides, while ‘Red Gold’ has lighter green leaves with pale green undersides.
