Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Aglaonema rotundum.

Variety denomination: The inventive variety of Aglaonema disclosed herein has been given the variety denomination ‘Sumalee’.

BACKGROUND OF THE INVENTION

Parentage: The claimed plant originated as an induced, whole-plant mutation. In 2017, the inventor initiated meristematic tissue culture propagation of an unnamed Aglaonema rotundum plant (not patented) at his commercial plant tissue culture laboratory in Nong Sam Wang, a subdistrict in the Nong Suea district of Pathum Thani province, Thailand. A plurality of parent plant cultures were treated with a combination of 1 mg/L of benzyl adenine (BA) and 0.1 mg/L of 2,4-dichlorophenoxyacetic acid (2,4-D) to induce mutation. Once the cultures were callused, they were treated with 1 mg/L benzyl adenine (BA) to induce foliar shoot development and growth. In October of 2018, once foliage developed, the inventor observed one culture that exhibited unique multicolored foliage characteristics relative to the parent. Said culture was deflasked and grown to a mature size to confirm the distinctness and stability of the characteristics first observed. In October of 2019, after further evaluation, it was determined that the new plant exhibited unique foliage coloration that would prove favorable for commercial marketability. The new variety was given the denomination ‘Sumalee’.

Asexual Reproduction: Asexual reproduction of ‘Sumalee’, by way of leaf cuttings, was first performed in April at the inventor's greenhouse in Nong Sam Wang, a subdistrict in the Nong Suea district of Pathum Thani province, Thailand. ‘Sumalee’ was subsequently reproduced by way of meristematic tissue culture propagation as well. Five successive generations so produced have shown that the unique features of the instant cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Sumalee’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Aglaonema cultivar ‘Sumalee’. These traits, in combination, distinguish ‘Sumalee’ as a new and distinct cultivar.

    • 1. Aglaonema ‘Sumalee’ exhibits petioles that are colored light red on the abaxial surface, generally appearing as a pink coloration; and
    • 2. Aglaonema ‘Sumalee’ exhibits prominent red veins on both the adaxial and abaxial foliar surfaces, generally appearing as a vibrant pink coloration; and
    • 3. Aglaonema ‘Sumalee’ exhibits a dark yellow-green adaxial foliar surface which is centrally and irregularly blotched with an array of colors ranging from very light orange-white and flecked with yellow-green to light yellow-green and suffused or flecked with very light orange-white to orange-white blotches that are heavily suffused with red and generally appearing as a vibrant pink coloration; and
    • 4. Aglaonema ‘Sumalee’ exhibits a very dark yellow-green abaxial laminar surface which is centrally and irregularly blotched with red, generally appearing as a vibrant pink coloration.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in August of 2022 describe an 18-month-old ‘Sumalee’ plant grown in a 20 cm nursery container at commercial greenhouse in Nong Sam Wang, a subdistrict in the Nong Suea district of Pathum Thani province, Thailand. Plants were produced using conventional greenhouse production protocols for Aglaonema which consisted of growing under 70-percent shade cloth, regular overhead irrigation every two days, and slow-release granular fertilizer applications at 4-month intervals, approximately. Preventative applications of Imadacloprid and Metalyx pesticides were utilized to prevent insect infestations and fungal infections. No photoperiodic treatments or artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘Sumalee’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic, and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 1986 (third edition).
