Abstract

A new and distinct pomegranate variety of Punica granatum named ‘EMEK’, particularly characterized by self-pollinating and self-fertile medium-sized tree with vigorous growth; good fruit productivity; medium-sized, mature fruit with uniform, dark pink to red skin color, red arils; and mature fruit which is of good eating quality, sweet flavor and good juice production.

Description

Botanical name of the genus and species of the plant claimed: Punica granatum L.

Variety denomination: ‘EMEK’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of a pomegranate tree, botanically known as Punica granatum L. of the Lythraceae family, and hereinafter referred to by the variety denomination ‘EMEK’.

The new Punica granatum ‘EMEK’ is a product of a controlled breeding program conducted by the inventors, Doron Holland, Irit Bar-Ya'akov and Kamel Hatib in the Yizre'el Valley, Israel. The objective of the breeding program was to develop a new Punica granatum variety with vigorous production of mature fruit and good eating quality.

Pomegranate seedlings of the inventors' pomegranate collection were planted in the Yizre'el Valley, Israel. The new Punica granatum ‘EMEK’ originated from open pollination of an unknown, unpatented Punica granatum variety. The new Punica granatum ‘EMEK’ was observed in 2003 and selected in 2006 by the inventors in a controlled environment in the Yizre'el Valley, Israel.

Asexual propagation of the new Punica granatum ‘EMEK’ by cuttings was first performed in February of 2006 in the Yizre'el Valley of 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. Resulting plants of the new Punica granatum were planted in 2007 in the Yizre'el Valley.

BRIEF DESCRIPTION OF THE INVENTION

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

- 1. self-pollinating and self-fertile medium-sized tree with vigorous growth;
- 2. Good fruit productivity;
- 3. Early ripening with harvest of mature fruit in mid-August in the Yizre'el Valley;
- 4. Medium-sized mature fruit with dark pink to red skin color and red arils; and
- 5. Mature fruit which is of good eating quality, sweet flavor and good juice production.

Of the many commercial varieties known to the present inventors, the most similar in comparison to the new Punica granatum ‘EMEK’ is Punica granatum ‘WONDERFUL’ (unpatented), in the following characteristics described in Table 1:

DETAILED BOTANICAL DESCRIPTION

The new Punica granatum ‘EMEK’ 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, and day length without any change in the genotype of the pomegranate tree.

The aforementioned photographs, together with the following observations, measurements and values describe trees of ‘EMEK’ as grown in the pomegranate farm in the Yizre'el Valley of Israel, under conditions which closely approximate those generally used in commercial practice. Seedlings of ‘EMEK’ were planted in clay grumusol (vertisol) soil at an elevation of about 100 meters above sea level, at lat. 32°42′N, long. 35°11′E. Yizre'el Valley is characterized by a Mediterranean subtropical climate, with an average annual rainfall of about 580 mm concentrated from November through March. Mean diurnal minimum temperature in January is 6° C. (43° F.), and mean diurnal maximum temperature in July is 33° C. (91° F.).

Unless otherwise stated, the detailed botanical description includes observations, measurements and values based on two-year-old ‘EMEK’ trees grown in the pomegranate farm in the Yizre'el Valley, Israel from 2006 to 2008. Quantified measurements are expressed as an average of measurements taken from a number of trees of ‘EMEK’. The measurements of any individual tree, or any group of trees, of the new variety may vary from the stated average.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately late morning in Yizre'el Valley, Israel.
