USPP16559P3 - Apple tree named ‘Nicogreen’ - Google Patents

Abstract

A new and distinct apple tree named ‘Nicogreen’. The new variety is the result of a cross between ‘Delcorf’ and ‘Granny Smith,’ and is most similar in appearance to ‘Granny Smith’. The new variety is distinguishable from ‘Granny Smith’ by its early maturation, which occurs approximately six weeks before ‘Granny Smith.’

Description

Latin name of the genus and species of the plant claimed: Malus communis Mill.

Variety denomination: ‘Nicogreen’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of apple tree, botanically known as Malus communis Mill. and hereinafter referred to by the name ‘Nicogreen’. This new and distinct cultivar was bred by inventor, Johan Nicolai, in Sint-Truiden, Belgium.

‘Nicogreen’ originated as a controlled cross between ‘Delcorf’ (unpatented) and ‘Granny Smith’ (unpatented). It most closely resembles ‘Granny Smith’ in appearance, although fruit of ‘Nicogreen’ matures approximately 6 weeks before ‘Granny Smith.’ Other differences between ‘Nicogreen’ and its parents are shown in the table below:

	Characteristic	‘Nicogreen’	‘Granny Smith’	‘Delcorf’
	Fruit Skin color	Green	Green (greener than	Yellow
			‘Nicogreen’)
	Overcolor of fruit	Yellow	No blush	Orange red,
				striped
	Flesh Color	White	White	Cream

The new variety has been asexually propagated by T-budding and bench grafting onto ‘M9’ and ‘MM111’ rootstocks, and has been demonstrated to remain true to type through successive generations.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The FIGURE illustrates the fruit of the new variety, ‘Nicogreen.’

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of the new and distinct variety of apple tree, based on observations of specimens grown in Sint-Truiden, Belgium. The observed plants were five years old. Colors are described according to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants of the new variety may vary from the stated average.
