Abstract

A new and distinct plant variety of the Cactaceae family which is sterile and in comparison to the `Christmas Magic` variety is principally distinguished by a growth habit which includes a greater natural tendency for branching without the need for pruning, a greater resistance to nutrient deficiencies, a greater resistance to stem breakage, a slightly lesser resistance to bud abscission, a habit of producing more blooms on specimens of comparable age at an earlier date in the blooming season and with a slightly longer bloom life, and a habit of producing blooms with a fuller bodied appearance and enhanced color.

Description

The invention relates to a new and distinct plant variety of the Cactaceae family and which has been named the Zygocactus truncatus `Christmas Magic II` by the inventor.

Certain plant varieties of the Cactaceae family are well known in the foliage plant market and among these are the varieties of the truncatus species of the Zygocactus genus and which are commonly referred to as "Christmas Cactus" for they tend to bloom in the months of November and December in the Northern Hemisphere and hence appear in the retail market area primarily during Thanksgiving and Christmas seasons.

Among the various Zygocactus truncatus varieties are the `Lavender Doll`, `Kris Kringle`, and `Christmas Magic` varieties. The `Lavender Doll` variety has a generally "purplish" colored bloom and its characteristics are set forth in U.S. Plant Pat. No. 3,690. The `Kris Kringle` variety has a generally "reddish" colored bloom and its characteristics are generally set forth in U.S. Plant Pat. No. 3,688. The `Christmas Magic` variety has a generally "reddish purple" or "purplish red" colored bloom and its characteristics are generally set forth in U.S. Plant Pat. No. 4,197.

Each of the three mentioned varieties is a fertile variety and the `Christmas Magic` variety has vastly improved growth habits in several areas when compared to the `Lavender Doll` and `Kris Kringle` varieties and which are of commercial significance. For example, the `Christmas Magic` variety in comparison to the other two varieties has a greater natural tendency to branch and produce a larger number of phylloclades without inducement by pruning during the growth period prior to initial blooming. The variety also has a substantially greater resistance to bud abscission than the `Lavender Doll` and `Kris Kringle` varieties while nevertheless retaining a similar resistance to nutrient deficiencies and fungus type diseases.

A general objective of the invention has been to develop a sterile variety of the Cactaceae family which preserves or improves upon most of the commercially important growth habits of the `Christmas Magic` variety and which provides a fuller bodied bloom with enhanced coloration. Other objectives have been to develop a sterile variety which exhibits many of the characteristics attributable to the `Christmas Magic` variety but which is capable of withstanding a greater amount of handling without stem breakage, has a still greater natural tendency for branching without the need for pruning, and exhibits a greater resistance to nutrient deficiencies.

The objectives of the invention have been fully realized by the development of the new plant variety hereinafter described in detail. The new plant variety was developed in a nursery located at Winter Garden,. Fla., as a hybrid secured by cross pollinating the flower of a plant specimen of a research variety that is a descendant of the `Kris Kringle` variety with pollen from a plant specimen of a research variety that is a descendant of the `Lavender Doll` variety. The seeds taken from the sterilized seed pod were cultivated at the mentioned nursery location and after prolonged observation of the seedlings, the hybridized plant of the new plant variety was selected and asexually reproduced by the inventor at the Winter Garden nursery by the propagation of stem cuttings taken from the original hybrid plant. The maternal and paternal plant varieties are both research varieties that have not appeared in the market area.

Through successive propagations, it has been ascertained that specimens of the new plant variety generally resemble the `Christmas Magic` variety but are distinguishable from specimens of this variety and the parent varieties, as well as other related varieties known to the inventor, by a growth habit which is evident in plant specimens propagated and grown under nursery conditions utilized in the growing of tropical plants at Winter Garden, Fla., as combining the following principal characteristics:

1. A growth rate, tendency for the formation of compact specimens, tendency for branching when pruned, specimen size at comparable stages of maturity and posture at maturity that are about the same as those of the `Christmas Magic` variety while, nevertheless, having a greater natural tendency for branching without the need for pruning when compared to the `Christmas Magic` variety.

2. A resistance to known problem diseases of the related varieties which is about the same as that found in the `Christmas Magic` variety while, nevertheless, having a greater resistance to nutrient deficiencies than the `Christmas Magic` variety.

3. A resistance to stem breakage which exceeds that of the `Christmas Magic` variety and which is attributed to specimens with stems with greater flexibility in comparison to those of the `Christmas Magic` variety.

4. A tendency for multiple bud formations on the tips of the branches that is about the same as that of the `Christmas Magic` variety while, nevertheless, having a slightly lesser resistance to bud abscission in comparison to the `Christmas Magic` variety.

5. A habit of producing more blooms on specimens of comparable age, at an earlier date in the blooming season, and with a slightly longer bloom life in comparison to the habits of the `Christmas Magic` variety.

6. A habit of producing blooms with a fuller bodied appearance that is attributed to a substantially larger number of tepals in the tube laminating series of tepals and tepals in the tube laminating and tube forming series of tepals which average slightly greater width dimensions in comparison to those of the `Christmas Magic` variety.

7. A bloom with enhanced coloration that is attributed to a greater and more uniform coverage of the marginal and center field areas of the blades of the tube laminating and tube forming series of tepals with color dominated by purplish red and/or reddish purplish hues in comparison to those of the `Christmas Magic` variety.

8. Sterility.

The accompanying drawings serve by color photography to illustrate the new plant variety and wherein one sheet photographically illustrates a 20 month old plant specimen that was propagated in March, pruned to 2 tiers above the propagated stem cutting in August of the year of propagation and thereafter in July of the following year again pruned to the 3rd tier above the propagated stem cutting. Another sheet photographically illustrates a phylloclade and typical bloom of the new plant variety while the third sheet photographically illustrates the bloom as generally seen along the axis of the perianth tube.

The following is a detailed description of the new plant variety with colors and hues, unless otherwise clearly indicated by the text through the absence of color notations being named in accord with the ISCC-NBS Method of Designating Colors, (U.S. Dept. of Commerce, National Bureau of Standards, Circular 553, issued Nov. 1, 1955) the named colors being interpreted from color notations derived by comparison with the color specimens in the "Neighboring Hues Edition" of the Munsell Book of Color, published by the Munsell Color Company, Inc., of Baltimore, Md. The description is further based on observations of well fertilized plants of less than 2 years of age from initial propagation and which were grown under 50-75% shaded glasshouse nursery conditions in the Winter Garden, Fla. area and wherein temperatures ranges from about 60° F. to about 85° F. during the winter months, from about 75° F. to about 95° F. during the summer months, and are ambient during the intervening periods.

VIII. Growth habit: The new plant variety has an upright and compact (dense) appearance, and a fast growth rate comparable to the `Christmas Magic` variety but nevertheless productive of more phylloclades than the `Christmas Magic` variety without inducement by pruning during the growth period preceding blooming. The new variety also has a resistance to stem breakage which exceeds that of the `Christmas Magic` variety.

Apart from the greater natural tendencies for branching without pruning, the tendencies for branching when pruned are about the same as those of the `Christmas Magic` variety. The new variety has about the same resistance as the `Christmas Magic` variety to known problem diseases of the related varieties but nevertheless has a greater resistance to nutrient deficiencies than those shown by the `Christmas Magic` variety. The new variety exhibits a similar tendency for multiple bud formations on the tips of the branches as shown by the `Christmas Magic` variety but in comparison exhibits a slightly lesser resistance to bud abscission.

In comparison to the `Christmas Magic` variety, the new variety has a habit of producing more blooms on specimens of comparable age, at a slightly earlier date in the blooming season, and the blooms exhibit a slightly longer bloom life, ranging from about 7 to 10 days. The blooms produced on specimens of the new variety have a fuller bodied appearance that is attributed to a larger number of tepals in the tube laminating series of tepals and to tepals in the tube laminating and tube forming series which average slightly greater width dimensions in comparison to those of the `Christmas Magic` variety. The bloom also exhibits enhanced coloration in comparison to the `Christmas Magic` variety and this is attributed to a greater and more uniform coverage of the marginal and center field areas of the blades of the tube laminating and tube forming series of tepals with color which is dominated by purplish red and/or reddish purple hues.

The following is a general description of a specimen of the new plant variety which was grown from the propagation of a single phylloclade in a nursery at Winter Garden, Fla.

Age of plant: 20 months from initial propagation of single phylloclade. The specimen was pruned to the second tier above the propagated phylloclade during the sixth month and thereafter to the third tier above the propagated phylloclade during the seventeenth month following propagation.

Branches from propagated phylloclades: 2.

Total number of new phylloclades on specimen: 77.

Claims

I claim:

1. The new and distinct plant variety of the Cactaceae family as described and illustrated herein and which is principally distinguished by a growth habit combining the following characteristics:

(1) a greater natural tendency for branching without the need for pruning than the `Christmas Magic` variety,

(2) a greater resistance to nutrient deficiencies than the `Christmas Magic` variety,

(3) a greater resistance to stem breakage than the `Christmas Magic` variety,

(4) a slightly lesser resistance to bud abscission than the `Christmas Magic` variety,

(5) a habit of producing more blooms on specimens of comparable age at an earlier date in the blooming season, and with a slightly longer bloom life than the `Christmas Magic` variety,

(6) a habit of producing blooms with a substantially larger number of tepals in the tube laminating series of tepals, and with tepals in the tube laminating and tube forming series of tepals which average slightly greater width dimensions in comparison to the `Christmas Magic` variety,

(7) a bloom with more uniform and greater coverage of the marginal and center field areas of the blades of the tube forming and tube laminating series of tepals with color dominated by purplish red and/or reddish purplish hues in comparison to the `Christmas Magic` variety,

(8) sterile specimens.
