ABSTRACT:

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium hybrid, and hereinafter referred to by the cultivar name Atwentyone.
The new cultivar is a product of a planned and controlled breeding program conducted by the Inventor in Altha, Fla. The objective of the breeding program is to create dwarf and early-flowering potted anthurium cultivars with attractive spathe color, good spathe longevity, and short production time. The new cultivar originated from a deliberate cross by the Inventor in 1993 between a proprietary Anthurium seedling selection identified as code No. 91-100-2, as the female or seed parent and a proprietary Anthurium seedling selection identified as code No. 91-9-32, as the male or pollen parent. The cultivar Atwentyone was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Altha, Fla., in 1994.
Asexual propagation of the new cultivar by tissue culture in Altha, Fla., has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.
SUMMARY OF THE INVENTION
The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, fertilizer rate, irrigation amount and frequency, and/or propagation procedures without, however, and variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Atwentyone’. These characteristics in combination distinguish ‘Atwentyone’ as a new and distinct cultivar:
1. Plants of the new Anthurium have a dwarf growth habit and are suitable for 7.5 to 15-cm containers.
2. Plants of the new Anthurium are vigorous.
3. Plants of the new Anthurium are freely and early flowering.
4. Plants of the new Anthurium have large spathes in proportion to the overall plant size.
5. Spathes of plants of the new Anthurium are held close to the foliage on relatively strong peduncles.
6. Young spathes of plants of the new Anthurium are bright red in color and exceptionally glossy.
7. Bright red spathe color is maintained under conditions of high temperatures and/or high light.
8. Spathes of plants of the new Anthurium are long-lasting. Ornamental value is maintained for several months after maturity.
Plants of the new Anthurium differ from plants of the female parent, the proprietary seedling selection identified as code No. 91-100-2, in the following characteristics:
1. Plants of the new Anthurium have broader leaves than plants of the selection 91-100-2.
2. Plants of the new Anthurium have red-colored spathes whereas plants of the selection 92-100-2 have pink-colored spathes.
Plants of the new Anthurium differ from plants of the male parent, the proprietary seedling selection identified as code No. 91-9-32, in the following characteristics:
1. Plants of the new Anthurium are smaller than plants of the selection 91-9-32.
2. Plants of the new Anthurium have smaller leaves than plants of the selection 91-9-32.
3. Plants of the new Anthurium have smaller spathes than plants of the selection 91-9-32.
Plants of the new Anthurium can be compared to the Anthurium cultivar Atwelve, disclosed in U.S. Plant Patent application Ser. No. 09/292,198. However, in side-by-side comparisons conducted in Altha, Fla., plants of the new Anthurium differ from plants of the cultivar Atwelve in the following characteristics:
1. Plants of the new Anthurium are slightly shorter than plants of the cultivars Atwelve.
2. Plants of the new Anthurium have a slightly longer crop time than plants of the cultivar Atwelve.
3. Leaves of plants of the new Anthurium have shorter apices and are hence shorter than leaves of plants of the cultivar Atwelve.
4. Leaves of plants of the new Anthurium have more cordate bases than leaves of plant of the cultivar Atwelve.
5. Plants of the new Anthurium have thinner peduncles than plants of the cultivar Atwelve.
6. Spathes of plants of the new Anthurium are situated slightly closer to the foliage than spathes of plants of the cultivar Atwelve.
7. Spathes of plants of the new Anthurium are less deltoid, slightly longer and narrower, less puckered, with more truncate bases and more aristate apices than spathes of plants of the cultivar Atwelve.
8. Spathes of plants of the new Anthurium are almost flat whereas spathes of the plants of the cultivar Atwelve are often reflexed.
9. Front surfaces of spathes of plants of the new Anthurium are glossier and maintain glossiness longer than front surfaces of spathes of plants of the cultivar Atwelve.
10. Spathes of plants of the new Anthurium maintain color longer under high temperatures and/or high light conditions than spathes of plants of the cultivar Atwelve.
11. Rear surfaces of spathes of plants of the new Anthurium are lighter red in color and with very limited to no green coloration on the veins whereas rear surfaces of spathes of plants of the cultivar Atwelve have dark green veins.
12. Spathes of plants of the new Anthurium age more attractively as spathe color changes from red to brownish red with increasing green with age whereas spathes of plants of the cultivar Atwelve gradually fade in color with age.
13. Spadices of plants of the new Anthurium mature and age slower than spadices of plants of the cultivar Atwelve.
14. Spadix rachis of the new Anthurium is yellow-cream in color whereas spadix rachis of plants of the cultivar Atwelve is green in color.
Plants of the new Anthurium can be compared to the Anthurium cultivar A2, disclosed in U.S. Plant Patent No. 10,210. However, in side-by-side comparisons conducted in Altha, Fla., plants of the new Anthurium differ from plants of the cultivar A2 primarily in spathe color and also in the following characteristics:
1. Plants of the new Anthurium are shorter than plants of the cultivar A2.
2. Plants of the new Anthurium flower slightly earlier than plants of the cultivar A2.
3. Leaves of plants of the new Anthurium are slightly darker green and have more cordate bases than leaves of plants of the cultivar A2.
4. Plants of the new Anthurium have shorter and thinner peduncles than plants of the cultivar A2.
5. Spathes of plants of the new Anthurium are held more horizontal (less upright) and are situated slightly closer to the foliage than spathes of plants of the cultivar A2.
6. Spathes of plants of the new Anthurium are slightly broader and glossier than spathes of plants of the cultivar A2.
7. Rear surfaces of spathes of plants of the new Anthurium have very limited to no green coloration whereas rear surfaces of spathes of plants of the cultivar A2 have light green-colored veins.
8. Spathes of plants of the new Anthurium maintain color longer especially under high temperatures and/or high light conditions than plants of the cultivar A2.
9. Spathes of plants of the new Anthurium age more attractively as spathe color changes from red to brownish red with increasing green with age whereas spathes of plants of the cultivar A2 gradually fade in color with age.
10. Spadices of plants of the new Anthurium mature and age slower than spadices of plants of the cultivar A2.
