Mango tree named ‘NOA’

Abstract

A new and distinct late ripening variety of mango tree (Mangifera indica L.) named ‘NOA’, particularly characterized by attractive fruit shape and color, excellent internal quality and low amount of fiber.

Description

Botanical name of the genus and species of the plant claimed: Mangifera indica L.

Variety denomination: ‘NOA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of a mango plant, botanically known as Mangifera indica L. of the Anacardiaceae family, and hereinafter referred to by the variety denomination ‘NOA’.

The new Mangifera indica L. variety ‘NOA’ is a product of a planned breeding program conducted by the inventors, Uri Lavi, Eli Tomer, David Saada, and Yuval Cohen at the Volcani Center, Bet Dagan, Israel. The objective of the breeding program was to develop a new, late ripening, Mangifera indica L. variety with attractive fruit shape and color, excellent internal quality and low amount of fiber.

The new Mangifera indica L. variety ‘NOA’ originated from open pollination of the Mangifera indica L. variety ‘SHELLY’ (registered, Israel Plant Breeders' Rights registration No. 2549; European CPVO Grant No. 21160) in the inventors' collection in 1995 in the Volcani Center, Bet Dagan, Israel. The new Mangifera indica L. ‘NOA’ was observed and selected by the inventors within the progeny of this open pollination in a controlled environment in 2001 in the Volcani Center, Bet Dagan, Israel.

Asexual propagation of the new Mangifera indica L. variety by grafting onto Mangifera indica L. rootstock ‘13/1’ (unpatented) was first performed in May 2002 in the Volcani Center, Bet Dagan, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new variety is firmly fixed and retained through successive generations of asexual propagation. The new variety propagates true-to-type.

BRIEF DESCRIPTION OF THE INVENTION

The following characteristics have been repeatedly observed and are determined to be characteristics of ‘NOA’, which in combination, distinguish this mango tree as a new, unique and distinct variety:

• • 1. Relatively late ripening;
  • 2. Attractive fruit shape and color;
  • 3. Excellent internal quality; and
  • 4. Low amount of fiber.

In comparison to the maternal parent variety, ‘SHELLY’ (registered, Israel Plant Breeders' Rights registration No. 2549; European CPVO Grant No. 21160), ‘NOA’ differs primarily in the traits listed in Table 1.

Of the many commercial varieties known to the present inventors, the most similar in comparison to the new Mangifera indica L. ‘NOA’ is Mangifera indica L. ‘KEITT’ (unpatented) which differ from the new mango ‘NOA’ in the characteristics described in Table 2:

DETAILED MORPHOLOGICAL DESCRIPTION

The new Mangifera indica L. variety ‘NOA’ has not been observed under all possible environmental conditions. The phenotype of the new variety may vary with variations in environment such as temperature, light intensity, day length, soil or pruning without any change in the genotype of the mango plant.

The aforementioned photographs, together with the following observations, measurements and values describe trees of ‘NOA’ as grown in the orchard at the Volcani Center, Bet Dagan, Israel, under conditions which closely approximate those generally used in commercial practice. The described trees were grafted on Mangifera indica L. rootstock ‘13/1’ (unpatented) and planted at a distance of 4×5 m in sandy red loam soil at an elevation of about 30 meters above sea level, irrigated with 6000 m³/hectare and fertilized with 1 liter/5 m³ of “sheffer” N:P:K 7:3:7″. Average annual rainfall is about 550 mm, with an average 350 mm of rainfall in winter (December to February). Mean diurnal minimum temperature in January is 7.2° C., and mean diurnal maximum temperature in July is 30.8° C.

Unless otherwise stated, the detailed morphological description includes observations, measurements and values taken from 2010 to 2012 and based on four-year-old ‘NOA’ trees grown in the orchard at the Volcani Center, Bet Dagan, Israel. Quantified measurements are expressed as an average or a range of measurements taken from a number of plants of ‘NOA’. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average or range.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), (1986 edition), except where general colors of ordinary significance are used. Color values were taken under daylight conditions in full sunlight in the Volcani Center, Bet Dagan, Israel.

All of the trees of ‘NOA’, insofar as they have been observed, have been consistent in all the characteristics described below.

• Classification:
  • • Botanical.—Mangifera indica L.
• Parentage:
  • • Female or seed parent.—Mangifera indica L. ‘SHELLY’ (registered).
