‘MINSYPIN3’

Abstract

A new and distinct Hibiscus cultivar named ‘MINSYPIN3’ is disclosed, characterized by large, single, pink flowers with a darker eye, up to 12 cm in diameter. Plants are well-branched, upright and vigorous. The new variety is a Hibiscus, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Hibiscus syriacus.

Variety denomination: ‘MINSYPIN3’.

BACKGROUND OF THE INVENTION

The new Hibiscus cultivar is a product of a planned breeding program conducted by the inventor, Patrick Pineau. The objective of the breeding program was to look for a new Hibiscus syriacus cultivars with large flowers and healthy, vigorous foliage. The cross resulting in this new variety was made during 2004.

The seed parent is the unpatented, proprietary Hibiscus syriacus ‘R3-08’. The pollen parent is the unpatented variety Hibiscus syriacus ‘Red Heart’. The new variety was identified and selected as a potentially interesting selection in October 2007. Selection was made at a nursery in La Menitre, France.

Asexual reproduction of the new cultivar ‘MINSYPIN3’ was first performed in January 2008 in La Menitre, France, by grafting. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in 6 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘MINSYPIN3’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘MINSYPIN3’ These characteristics in combination distinguish ‘MINSYPIN3’ as a new and distinct Hibiscus cultivar:

• • 1. Large pink single flower with a red eye.
  • 2. Erect plant form.
  • 3. Well branched.
  • 4. Vigorous.

PARENT COMPARISON

Plants of the new cultivar ‘MINSYPIN3’ are similar to plants of the seed parent variety in most horticultural characteristics, however, plants of the new cultivar ‘MINSYPIN3’ differ in the following;

• • 1. The new variety has more branches than the seed parent.
  • 2. The new variety has a dark eye, the seed parent does not.

Plants of the new cultivar ‘MINSYPIN3’ are similar to plants of the pollen parent variety Hibiscus syriacus, ‘Red Heart’ in most horticultural characteristics, however, plants of the new cultivar ‘MINSYPIN3’ differ in the following;

• • 1. ‘Minsypin3’ is more vigorous with more branches than the pollen parent.
  • 2. ‘Minsypin3’ has a pink flower with a dark eye, the pollen parent has a white flower.
  • 3. ‘Minsypin3’ has a larger flower (12 cm) than the pollen parent (8-10 cm).
  • 4. ‘Minsypin3’ has small pink petaloid stamens, the pollen parent has none.
  • 5. ‘Minsypin3’ has got longer red feathering (0.5 to 1 cm) which is absent in the pollen parent.
  • 6. ‘Minsypin3’ has shorter pubescence on its seed than the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘MINSYPIN3’ can be compared to the variety Hibiscus syriacus unpatented. These varieties are similar in most horticultural characteristics however, ‘MINSYPIN3’ differs in the following:

• • 1. ‘Minsypin3’ is more erect than ‘Flogi’.
  • 2. ‘Minsypin3’ has a larger flower (12 cm) than ‘Flogi’ (10 cm).
  • 3. ‘Minsypin3’ has lighter pink petals color than ‘Flogi’.
  • 4. ‘Minsypin3’ has small pink petaloid stamens ‘Flogi’, has none.
  • 5. ‘Minsypin3’ has got longer red feathering (0.5 to 1 cm) than ‘Flogi’ (0.5 cm).
  • 6. ‘Minsypin3’ produces more seed than ‘Flogi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘MINSYPIN3’ grown in the ground at approximately 10 years old in La Menitre, France.
