Description

Botanical name of the genus of the Interspecific Cross of the plant claimed: Hippeastrum Herb,. syn. Amaryllis

Variety denomination: ‘RUBY STAR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct interspecific hybrid variety of Hippeastrum, botanically known as Hippeastrum Herb., syn. Amaryllis, of the Amaryllidaceae family, and hereinafter referred to by the name ‘RUBY STAR’. The Hippeastrum genus is native to tropical and subtropical regions of South America and the Caribbean, and includes more than 80 different species and several hundred hybrids.

The new Hippeastrum ‘RUBY STAR’ is a product of a controlled breeding program conducted by the inventors, Dorit Sandler-Ziv, Corneliu Fintea, Aurel Ion, Avner Cohen, Marina Baizerman and Ahuva Daous, in Bet-Dagan, Israel. The objective of the breeding program was to develop a new Hippeastrum variety with excellent ornamental characteristics, adapted to bulb production under Israeli climatic conditions and suitable for both cut flower and pot production worldwide.

The new Hippeastrum ‘RUBY STAR’ originated from a cross made by the inventors in 2000 in Bet-Dagan, Israel. The female or seed parent is the unpatented, wild-type Hippeastrum papillio designated WT30. The male or pollen parent is the unpatented, interspecific Hippeastrum hybrid designated 97/4 (H. vittatum ‘WHITE’×wild-type H. cybister designated WT40). The new Hippeastrum ‘RUBY STAR’ was selected by the inventors as a single flowering plant from the progeny of the stated cross in a controlled environment in 2003 in Bet-Dagan, Israel.

Asexual propagation of the new Hippeastrum ‘RUBY STAR’ using the “twin-scaling” method (division of the mother bulb into about 12 vertical segments which are subsequently subdivided into 5 to 6 twin-scale units) was first performed in September, 2004, in Bet-Dagan, Israel. The twin-scale units are dipped for 15 minutes in 0.2% BENLATE and 0.5% MARPAN to prevent fungal infection, then the segments are air dried for 3-4 hours and placed in moist Vermiculite no. 2 (8% to 10% moisture) and incubated at 22° C. to 24° C. for 3 to 4 months. The resulting bulblets are planted in coco-peat and Tuff 0.8 (80:20%) and grown for 2 years until they flower for the first time. Of the twin scales first propagated in September, 2004, the resulting bulbs first flowered in the winter of 2007, and 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 traits have been repeatedly observed and are determined to be characteristics of ‘RUBY STAR’, which in combination distinguish this Hippeastrum as a new, unique and distinct variety:

    • 1. star-shaped flower, measuring about 18 to 20 cm in length and about 14 to 17 cm in diameter, and with a unique color pattern of primarily dark red (RHS 53 B) with yellow-greenish (RHS 145 B) stripes and greyed-purple (RHS 183 B) veining.

Plants of the new Hippeastrum ‘RUBY STAR’ differ from plants of the female or seed parent, the unpatented, wild-type Hippeastrum papillio designated WT30, in the following characteristics described in Table 1.

 DETAILED BOTANICAL DESCRIPTION

The new Hippeastrum ‘RUBY STAR’ 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 plant.

The aforementioned photographs, together with the following observations, measurements and values describe plants of ‘RUBY STAR’ as grown in a greenhouse in Bet-Dagan, Israel, under conditions which closely approximate those generally used in commercial practice.

Mother bulbs of ‘RUBY STAR’ (about 28 to 30 cm in circumference) are cut into 12 vertical segments which are subsequently subdivided into 5 to 6 twin-scale units. The twin-scale units are dipped for 15 minutes in 0.2% BENLATE and 0.5% MARPAN to prevent fungal infection, then the twin-scale units are air dried for 3-4 hours and placed in moist Vermiculite no. 2 (8-10% moisture) and incubated at 22° C. to 24° C. for 3-4 months. The resulting bulblets are planted and grown in raised, heated soil beds (soil temperature maintained at an average temperature of about 20° C. to 22° C.) in coco-peat and Tuff 0.8 (80:20%) and grown for 2 years until they flower for the first time.

Plants of ‘RUBY STAR’ have been grown in an insect-proof greenhouse, covered with a permanent polycarbonate roof with movable polyethylene curtains, and under 50% shading. Drip irrigation is administered at 80-100 m3/ha and a liquid fertilize is applied of (NPK 5:3:8) 50 ppm. Plants of ‘RUBY STAR’ are grown with an average winter air temperature of about 12° C. to 25° C. during the day and about 6° C. to 12° C. during the evening and an average summer air temperature of about 22° C. to 38° C. during the day and about 18° C. to 22° C. during the evening. Plants of ‘RUBY STAR’ reach full growth about 6 to 10 weeks after planting cured bulbs. Quantified measurements are expressed as an average or a range of measurements taken from a number of plants of ‘RUBY STAR’. 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 at approximately noon in full sunlight in Bet Dagan, Israel.
