USPP32540P2 - Magnolia plant named ‘MGMIG2007’ - Google Patents

Abstract

A new cultivar of Magnolia plant named ‘MGMIG2007’ that is characterized by a rounded bush shape, small leaves, upright cup shaped flowers having red-purple tepals, slender dark green branches with short internodes and moderate quantities of flowers during the Summer.

Description

Botanical classification: Magnolia hybrid.

Variety denomination: ‘MGMIG2007’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Magnolia plant botanically known as Magnolia hybrid and hereinafter referred to by the cultivar name ‘MGMIG2007’.

The new cultivar is the product of a breeding program conducted by the inventor in a cultivated area of Waitara, New Zealand. The objective of the breeding program is to develop new Magnolia cultivars that are smaller in size and have attractive flower colors.

‘MGMIG2007’ originated from crossing the female or seed parent an unnamed Magnolia cultivar and the male or pollen parent Magnolia soulangeana x lilliflora ‘Genie’ (U.S. Plant Pat. No. 20,748). The crossing was conducted in 2003 in a controlled environment. The cultivar ‘MGMIG2007’ was selected by the inventor in 2008 as a single plant within the progeny of the stated cross in a cultivated area of Waitara, New Zealand.

Asexual reproduction of the new cultivar ‘MGMIG2007’ by field budding was first performed in 2008 in Waitara, New Zealand. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Magnolia cultivar ‘MGMIG2007’. These traits in combination distinguish ‘MGMIG2007’ as a new and distinct cultivar.

• • 1. Magnolia ‘MGMIG2007’ exhibits a rounded bush shape.
  • 2. Magnolia ‘MGMIG2007’ exhibits small leaves.
  • 3. Magnolia ‘MGMIG2007’ exhibits upright cup shaped flowers having red-purple tepals.
  • 4. Magnolia ‘MGMIG2007’ exhibits slender dark green branches with short internodes.
  • 5. Magnolia ‘MGMIG2007’ exhibits flower production during the Summer in a moderate quantity.

The closest comparison variety is Magnolia ‘Mini Mouse’ (not patented). ‘MGMIG2007’ is different than ‘Mini Mouse’ in the following characteristics:

• • 1. Magnolia ‘MGMIG2007’ exhibits a rounded bush shape. In contrast, ‘Mini Mouse’ has an upright bush shape.
  • 2. Magnolia ‘MGMIG2007’ exhibits small leaves. In contrast, the leaves of ‘Mini Mouse’ are larger.
  • 3. Magnolia ‘MGMIG2007’ exhibits upright cup shaped flowers having red-purple tepals. In contrast, the flowers of ‘Mini Mouse’ are elongated in shape and purple-pink in color.
  • 4. Magnolia ‘MGMIG2007’ exhibits short internodes. In contrast, the internodes of ‘Mini Mouse’ are longer.
  • 5. Magnolia ‘MGMIG2007’ exhibits flower production during the Summer in a moderate quantity. In contrast, ‘Mini Mouse’ produces very few flowers during the Summer.

‘MGMIG2007’ is different than the female parent plant in the following characteristics:

• • 1. Magnolia ‘MGMIG2007’ exhibits a rounded bush shape. In contrast, the female parent plant has a tree shape.
  • 2. Magnolia ‘MGMIG2007’ exhibits small leaves. In contrast, the leaves of the female parent plant are larger.
  • 3. Magnolia ‘MGMIG2007’ exhibits slender branches and short internodes. In contrast, the branches of the female parent plant are thicker and the internodes are longer.
  • 4. Magnolia ‘MGMIG2007’ exhibits upright cup shaped flowers having red-purple tepals. In contrast, the flowers of the female parent plant have an open cup and saucer shape.

‘MGMIG2007’ is different than the male parent plant in the following characteristics:

• • 1. Magnolia ‘MGMIG2007’ exhibits upright cup shaped flowers having red-purple tepals. In contrast, the flowers of the male parent plant are less cup shaped, more spreading and have red tepals.
  • 2. Magnolia ‘MGMIG2007’ exhibits short internodes. In contrast, the internodes of the male parent plant are longer.
  • 3. Magnolia ‘MGMIG2007’ exhibits flower production during the Summer in a moderate quantity. In contrast, the male parent plant produces fewer flowers during the Summer.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Magnolia cultivar named ‘MGMIG2007’. Data was collected in Waitara, New Zealand from 2 year old field grown plants. The time of year was Spring and the average temperature was 15° Centigrade during the day and 9° Centigrade at night. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2015 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘MGMIG2007’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
