ABSTRACT:
Latin name of the genus and species of the plant claimed: Spathiphyllum hybrid.
Variety denomination: ‘Sweet Benito’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Spathiphyllum plant, hereinafter referred to by the cultivar name ‘Sweet Benito’.
The new cultivar originated from a cross made in a controlled breeding program in Monster, The Netherlands. The female parent is ‘94225-1’ (unpatented). The male parent is ‘93165-16’ (unpatented). ‘Sweet Benito’ was discovered and selected by the inventor, Petrus C. M. Olsthoorn, as a flowering plant within the progeny of the stated cross in a controlled environment in Monster, The Netherlands.
Asexual reproduction of the new cultivar was first performed by tissue culture in week 16 of 1997 in Honselersdijk, the Netherlands and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction and reproduces true-to-type.
BRIEF DESCRIPTION OF THE INVENTION
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Sweet Benito’ which in combination distinguish this Spathiphyllum as a new and distinct cultivar:
1. Early shoot production;
2. Dark and glossy leaves;
3. Long-lasting inflorescence color and duration;
4. High inflorescence production;
5. Compact plant size; and
6. Good light sensitivity/resistance of leaves.
‘Sweet Benito’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Honselersdijk, The Netherlands under conditions which closely approximate those generally used in commercial practice.
Of the many commercial cultivars known to the present inventor, the most similiar in comparison to ‘Sweet Benito’ is the cultivar ‘Cupido’ (unpatented). ‘Sweet Benito’ produces shoots early, within fifteen weeks after tissue culture the first one appears. ‘Sweet Benito’ has darker and glossier leaves than ‘Cupido’. The white inflorescence color of ‘Sweet Benito’ lasts longer than the inflorescence color of ‘Cupido’. The inflorescence of ‘Sweet Benito’ is a little smaller and rounder than that of ‘Cupido’. ‘Sweet Benito’ produces 8-15 inflorescences (depending on pot size) whereas ‘Cupido’ produces between 8 and 10. ‘Sweet Benito’ produces up to 8 inflorescences at once whereas ‘Cupido’ produces only 2 to 3 inflorescences at once. Plant height of ‘Sweet Benito’ is approximately 60 percent that of ‘Cupido's’. The leaves of ‘Sweet Benito’ are narrower than the leaves of ‘Cupido’. The main leaf vein of ‘Sweet Benito’ is lighter in color than the leaves themselves whereas the main leaf vein color of ‘Cupido’ is the same color as the leaves. ‘Cupido’ is more sensitive to light than ‘Sweet Benito’ causing the color of the leaves of ‘Cupido’ to lighten faster. Finally, in order to get the shoots of a Spathiphyllum to flower, gibberellic acid is added. ‘Cupido’ needs more than twice the concentration of this hormone than ‘Sweet Benito’ to get the same result.
