plant named ‘MGPRO2008’

Abstract

A new cultivar of Magnolia plant named ‘MGPRO2008’ that is characterized by a compact habit, medium sized leaves, flowers having bright pink tepals and a large number of flowers during the Summer.

Description

Botanical classification: Magnolia hybrid.

Variety denomination: ‘MGPRO2008’.

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 ‘MGPRO2008’.

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.

‘MGPRO2008’ originated from crossing the female or seed parent Magnolia hybrid ‘Amethyst Flame’ (not patented) and the male or pollen parent Magnolia soulangeana x lilliflora ‘Genie’ (U.S. Plant Pat. No. 20,748). The crossing was conducted in 2004 in a controlled environment. The cultivar ‘MGPRO2008’ was selected by the inventor in 2009 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 ‘MGPRO2008’ by field budding was first performed in 2009 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 ‘MGPRO2008’. These traits in combination distinguish ‘MGPRO2008’ as a new and distinct cultivar.

• • 1. Magnolia ‘MGPRO2008’ exhibits a compact habit.
  • 2. Magnolia ‘MGPRO2008’ exhibits medium sized leaves.
  • 3. Magnolia ‘MGPRO2008’ exhibits flowers having bright pink tepals.
  • 4. Magnolia ‘MGPRO2008’ exhibits a large number of flowers during the Summer.

The closest comparison variety is Magnolia ‘Susan’ (not patented).

‘MGPRO2008’ is different than ‘Susan’ in the following characteristics:

• • 1. Magnolia ‘MGPRO2008’ exhibits a compact habit. In contrast, ‘Susan’ has a more dense upright habit.
  • 2. Magnolia ‘MGPRO2008’ exhibits medium sized leaves. In contrast, the leaves of ‘Susan’ are narrower.
  • 3. Magnolia ‘MGPRO2008’ exhibits flowers having bright pink tepals. In contrast, the tepals of ‘Susan’ are purple-pink.
  • 4. Magnolia ‘MGPRO2008’ exhibits a large number of flowers during the Summer. In contrast, ‘Susan’ produces a smaller number of flowers during the Summer.

‘MGPRO2008’ is different than the female parent plant in the following characteristics:

• • 1. Magnolia ‘MGPRO2008’ exhibits a compact habit. In contrast, the female parent plant has a broader habit with spreading branches.
  • 2. Magnolia ‘MGPRO2008’ exhibits medium sized leaves. In contrast, the leaves of the female parent plant are larger.
  • 3. Magnolia ‘MGPRO2008’ exhibits flowers having bright pink tepals. In contrast, the tepals of the female parent plant are red-purple turning to pale purple.
  • 4. Magnolia ‘MGPRO2008’ exhibits a large number of flowers during the Summer. In contrast, the female parent plant produces a smaller number of flowers during the Summer.

‘MGPRO2008’ is different than the male parent plant in the following characteristics:

• • 1. Magnolia ‘MGPRO2008’ exhibits a compact habit. In contrast, the male parent plant has a more open pyramidal habit.
  • 2. Magnolia ‘MGPRO2008’ exhibits medium sized leaves. In contrast, the leaves of the male parent plant are smaller.
  • 3. Magnolia ‘MGPRO2008’ exhibits flowers having bright pink tepals. In contrast, the tepals of the male parent plant are red.
  • 4. Magnolia ‘MGPRO2008’ exhibits a large number of flowers during the Summer. In contrast, the male parent plant produces a smaller number of flowers during the Summer.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Magnolia cultivar named ‘MGPRO2008’. Data was collected in Waitara, New Zealand from 5 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. ‘MGPRO2008’ 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.
