Anthurium plant named ‘Favorita’

Abstract

A new and distinct cultivar of Anthurium is provided. It is a medium size plant, suitable for production in 15-cm to 20-cm containers, with vigorous growth; full and symmetrical growth habit; early and abundant branching; early, abundant and year-round flowering; and resistance to Xanthomonas campestris pv. dieffenbachiae. Exceptionally dark green, relatively large, glossy leaves create a sharp contrast with bright orange-red and glossy spathes held immediately above foliage on straight, strong, relatively thick peduncles.

Description

BOTANICAL CLASSIFICATION

Anthurium hybrid.

VARIETY DENOMINATION

‘Favorita’.

BACKGROUND OF THE INVENTION

This inventions relates to a new and distinct cultivar of anthurium plant, botanically known as Anthurium hybrid, and hereinafter referred to by the cultivar name Favorita.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Altha, Fla. The objective of the program was to develop a vigorous, well branching pot Anthurium cultivar resistant to Xanthomonas campestris pv. dieffenbachiae, with attractive foliage and orange spathes. The new Anthurium was discovered and selected by the Inventor in 1998 as a seedling within the progeny of a cross made in 1995 in a controlled environment in Altha, Fla. The female parent was a proprietary Anthurium seedling selection identified by the code number 91-11-48, obtained by the Inventor in the same breeding program, not patented. The male parent was a selected clone of Anthurium hybrid cultivar Lady Jane identified by the code number 941, not patented.

Asexual propagation of ‘Favorita’, since 1998, by means of tissue culture in Altha, Fla. has established that the unique characteristics of this new cultivar are in fact stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Anthurium cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and/or horticultural practices such as temperature, light intensity, day length, fertilization, irrigation, propagation procedures etc., without any variance in genotype.

The following traits have been repeatedly observed and in combination distinguish ‘Favorita’ as a new and distinct cultivar of pot Anthurium:

1. Medium size plant, appropriate for 15-cm to 20-cm containers;

2. Symmetrical, rounded and full growth habit;

3. Vigorous growth;

4. Early and abundant branching;

5. Early, abundant and year-round flowering;

6. Relatively large, glossy and exceptionally dark green leaf blades;

7. Spathes very glossy, orange-red, especially when young, and maintaining color relatively well;

8. Spathes held directly above foliage, on straight, strong and relatively thick peduncles;

9. Resistance to Xanthomonas campestris pv. dieffenbachiae.

Plants of ‘Favorita’ are distinguished from plants of the female parent, a proprietary Anthurium seedling selection identified by the code number 91-11-48, by its smaller size; earlier and more abundant branching; earlier flowering; smaller, darker green and glossier leaf blades; spathes smaller, flatter and more horizontal, held closer to foliage, glossier and orange-red as opposed to dark pink-red spathes of seedling 91-11-48; and straight pink-purple spadices as opposed to curved, dark purple spadices of 91-11-48.

Plants of ‘Favorita’ are distinguished from plants of the male parent, a selected clone of Anthurium hybrid cultivar Lady Jane identified by the code number 941, by its more vigorous growth, earlier flowering; longer leaf blades; spathes more ovate, wider, with lower length:width ratio, orange-red in color and held above foliage as opposed to dark pink spathes of Lady Jane # 941, often held among foliage; and by pink-purple spadices as opposed to pinkish-cream spadices of Lady Jane #941.

The new cultivar can be compared to its siblings, cultivars: ‘Salsa’ U.S. Plant patent application Ser. No. 09/960,456 and ‘Valentine’ U.S. Plant patent application Ser. No. 09/960,455. The comparisons were made on plants of the same age, grown side-by-side under the same greenhouse conditions in Altha, Fla.

Plants of the new Anthurium cultivar differ from plants of the cultivar Salsa in the following characteristics:

1. Plants of ‘Favorita’ start branching earlier and flower more abundantly than plants of ‘Salsa’.

2. Foliage of ‘Favorita’ is taller than foliage of ‘Salsa’.

3. Leaf blades of ‘Favorita’ are darker green than leaf blades of ‘Salsa’.

4. Spathes of ‘Favorita’ are smaller, held closer to foliage and are orange-red, whereas spathes of ‘Salsa’ are dark pink-red.

5. Spadices of ‘Favorita’ are pink-purple, whereas spadices of ‘Salsa’ are cream-colored.

Plants of the new Anthurium cultivar differ from plants of the cultivar Valentine in the following characteristics:

1. Plants of ‘Favorita’ are larger, branch less abundantly and have slightly more open growth habit than plants of ‘Valentine’.

2. Plants of ‘Favorita’ start flowering earlier, but flower less abundantly than plants of ‘Valentine’.

3. Leaf blades of ‘Favorita’ are larger, darker green and glossier than leaf blades of ‘Valentine’.

4. Peduncles of ‘Favorita’ are thicker, stronger and longer than peduncles of ‘Valentine’.

5. Spathes of ‘Favorita’ are held closer to foliage, are larger and have shorter longevity on the plant than spathes of ‘Valentine’.

6. Spathes of ‘Favorita’ are orange-red, whereas spathes of ‘Valentine’ are deep red.

7. Spadices of ‘Favorita’ are pink-purple, whereas spadices of ‘Valentine’ are cream-colored.

The new cultivar can be compared to the known Anthurium cultivars: ‘Orange Hot’, not patented and ‘75-10’, disclosed in U.S. Plant Pat. No. 9,355, a/k/a/ Red Hot™. The comparisons were made on plants of the same age, grown side-by-side under the same greenhouse conditions in Altha, Fla.

Plants of the new Anthurium cultivar differ from plants of the cultivar Orange Hot in the following characteristics:

1. Leaf blades of ‘Favorita’ are larger and darker green than leaf blades of ‘Orange Hot’.

2. Inflorescences of ‘Favorita’ are of good quality from the onset of flowering, whereas several first spathes produced by plants of ‘Orange Hot’ are very small and deformed.

3. Spathes of ‘Favorita’ are held closer to foliage on thicker, stronger and more vertical peduncles than spathes of ‘Orange Hot’.

4. Spathes of ‘Favorita’ are almost horizontal, flat and non-puckered, whereas spathes of ‘Orange Hot’ are oblique and slightly puckered.

5. Young spathes of ‘Favorita’ are glossier, have a brighter, more distinct orange-red color than young spathes of ‘Orange Hot’ and maintain color and gloss longer.

6. Spadices of ‘Favorita’ are straight, whereas spadices of ‘Orange Hot’ are usually curved.

Plants of the new Anthurium cultivar differ from plants of the cultivar 75-10 in the following characteristics:

1. Leaf blades of ‘Favorita’ are larger and darker green than leaf blades of ‘75-10’.

2. Inflorescenes of ‘Favorita’ are of a good quality from the onset of flowering, whereas several first spathes produced by plants of ‘75-10’ are very small and deformed.

3. Spathes of ‘Favorita’ are held closer to foliage on thicker, stronger and more vertical peduncles than spathes of ‘75-10’.

4. Peduncles of ‘Favorita’ are brownish green, whereas peduncles of ‘75-10’ are dark purple.

5. Spathes of ‘Favorita’ are orange-red, almost horizontal, flat and non-puckered, whereas spathes of ‘75-10’ are red, oblique and slightly puckered.

6. Spathes of ‘Favorita’ maintain color and gloss longer than spathes of ‘75-10’.

7. Spadices of ‘Favorita’ are straight and pink-purple, whereas spadices of ‘75-10’ are usually curved and dark purple.

BOTANICAL DESCRIPTION OF THE NEW CULTIVAR

The following observations and measurements were recorded in February and March 2001, on plants grown in a polycarbonate-covered greenhouse in Altha, Fla. under conditions which closely approximate those used in commercial horticultural practice. During growth of these plants day temperature in the greenhouse ranged between 23 and 28° C., night temperature ranged between 20 and 23° C., and light level ranged between 800 and 1500 foot-candles. Plants used for these observations were grown as single plants in 15-cm containers and were about 15 months from planting tissue culture-produced microcuttings.

Mature, fully developed plants were used for the following observations and measurements unless otherwise indicated. Numerical measurements represent means from typical plants of ‘Favorita’. Color references are made to The R.H.S. Colour Chart, except where general color terms of ordinary significance are used. Color values were determined under natural light of approximately 860 to 2000 foot-candles.
