Alstroemeria variety named Stapiros

Abstract

A new and distinct Alstroemeria variety which is a natural mutation of the variety `Starosello` and which differs in petal coloration.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Alstroemeria discovered as a sport of the variety seedling named `Starosello` among my collection of cultivated Alstroemeria maintained under controlled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer, The Netherlands. The varietal denomination of the new variety is `Stapiros`.

The first act of asexual reproduction of `Stapiros` was in Aalsmeer, The Netherlands by propagation by dividing rootstocks. Asexual reproduction through successive generations has demonstrated that the combination of characteristics as herein disclosed for `Stapiros` are firmly fixed and retained through successive generations of asexual reproduction.

`Stapiros` has not been observed under all possible environmental conditions. Phenotypic expression may vary with variations in environment such as temperature, light intensity, day length and growing and cultural conditions.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstroemeria, `Stapiros` are of a different color than the parent while maintaining the parents good growth and flowering characteristics, as herein described. The variety is a spontaneous mutant of `Starosello` and differs from the parent mainly in the color of the petals and is similar in other respects. The inner side color of `Starosello` petals is near 50B and the other side is near 52B, for plants grown under glass in the Netherlands.

The plant produces numerous flowering stems, which is a desirable characteristic in a cut flower variety. `Stapiros` grows productively under greenhouse conditions and is also reproducible both by division of rhizomes and by tissue culture.

DESCRIPTION OF ILLUSTRATIONS

The new variety of Alstroemeria hybrid is illustrated in the accompanying illustration, which shows typical flower and vegetation characteristics, with colors being as nearly true as is possible for illustrations of this type.
