Atilh 5 00 U.S. Cl. Pit-88 1 Claim ABSTRACT 0F THE DISCLOSURE A new and distinct hybrid plant variety of the Cactaceae family obtained through cross-pollination of plants of the Zygocactus truncatus parma Variety and a Zygocactus truncatus variety known commercially as Christmas Cheer is principally distinguished from its parents and known related varieties by a growth habit which combines a fast growth rate, an upright and compact appearance with broader cladophylls than its maternal parent, substantially less flower bud abscission than its maternal parent, substantial resistance to nutrient deficiencies and fungus-type diseases, and a generally larger flower than its maternal parent and which has a bloom life from about 5 to about 8 days, perianth tube laminating tepals with marginal blade areas that in color are dominated by yellowish pink, pink red and/or purplish red hues, and perianth tube forming tepals with blades that are more recurve than those of the maternal parent and have marginal blade areas which in color are dominated by purplish red, red and/ or pink hues.

The invention relates to a new and distinct plant Variety of the Cactaceae family and which has been named the Zygocacus truncazns Kris Kringle by the inventor.

Certain plant varieties of the Cactaceae family are well known in the foliage plant market and among these are those of the Zygocacrus trnncatus variety commonly konwn as the Christmas Cheer variety. A lesser known variety that has appeared in the foliage plant market is the Zygocactus truncatus parma. These varieties tend to bolom in the months of November and December in the northern hemisphere and hence their appearance in the retail market area is primarily during the Thanksgiving and Christmas seasons.

The parma variety has what may be called a reddish colored bloom that is appealing to purchasers during the Thanksgiving-Christmas holiday season. The bloom life however varies from about 3 to about 6 days and this provides a tolerable shelf life to some merchants at the retail level of sales while others find the bloom life to be unacceptable. The variety suffers from the further disadvantage that many of the flower buds which start to mature fail to reach maturity and instead drop from the stems. Tests have indicated that this bud abscission problem is aggravated when the plant specimens are housed in closed cartons such as are used for shipping purposes in the industry. Growers are accordingly reluctant to grow the variety because of the transportation delays and large costs that are involved in manually selecting specimens for shipment which are at the proper stage of budding to provide reasonable assurance of mature blooming when the plants reach their destination. The variety also has a low tolerance to nutrient deficiencies and has a resistance to fungus-type diseases which is less than satisfactory to many growers.

The variety commonly known as Christmas Cheer has a bloom life which is generally acceptable to most retail merchants and which is in the area of from about 5 to 8 days. The bloom has what may be called a salmon color however and this color is less appealing to the general public during the Thanksgiving-Christmas season. There is accordingly a need for a Zygocactus truncatus variety which blooms in the Thanksgiving-Christmas season and has a reddish colored bloom and a bloom life which provides a suitable shelf life at the retail level of sa es.

A general object of the invention has been to develop a variety of the Cactaceae family which would have a reddish colored bloom along with a more acceptable bloom life and resistance to flower bud abscisison than the parma variety. Yet another object of the invention has been to develop a variety having the foregoing general objective and which is faster growing and more compact in appearance than the parma variety.

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 of the Zygocactus truncatus parma variety with pollen from a plant of the Zygocactus truncatus variety commonly known as Christmas Cheer. The seeds taken from the fertilized seed pod of the parma variety were cultivated at the mentioned nursery location and after prolonged observation of the seedlings the hybridized plant ofthe 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 Through successive propagations, it has been ascertained that plants of the new variety generally resemble the parent varieties but are distinguishable from the parent varieties and from other related varieties known t0 the inventor by a growth habit which is evident in plants propagated and grown under nursery conditions utilized in the growing of tropical plants at Winter Garden, Fla., as 'combining the following principal characterisitcs:

l. A faster growth rate than its maternal parent,

2. A more upright and compact (denser) appearance than its parents, as evidenced by more erect stems with heavier (more frequent) branching,

3. Broader cladophylls than its maternal parent,

4. Substantially greater resistance to flower bud abscission than its maternal parent,

5. Greater resistance to nutrient deficiencies and fungustype diseases than its parents, and

6. A generally larger flower than its maternal parent and which has (a) A bloom life from about 5 to about 8 days,

(b) Perianth tube laminating tepals with marginal blade areas that in color are dominated by yellowish pink, pink, red and/or purplish red hues, and

(c) Perianth tube forming tepals with blades that are more recurved than those of the maternal parent and marginal blade areas that in color are dominated by purplish red, and/or pink hues.

The accompanying drawing serves, by color photographic means, to illustrate the new plant variety and wherein:

FIG. 1 is a color photograph of a plant specimen of the new plant variety; and

ases

FIG. 2 is a color photograph showing a fully opened bloom of the new variety together with buds of the new variety in earlier stages of bloom maturity.

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 colons (U.S. Department 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 current Neighboring Hues Edition of the Munsell Book of Color, published by the Munsell Color Company, Inc., of Baltimore, Md. The following description is further based on observations of well fertilized plants of less than one year of age from initial propagation and which were grown under 50-70% shaded glasshouse nursery conditions in the Winter Garden, Fla., area and wherein temperatures range from 60 to 85 F. during the winter months, from 75 to 95 F. during the summer months and are ambient during intervening periods.
