Genus and species: Ananas comosus.
Variety denomination: ‘VINTAGE RUBY’.
This application includes material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent disclosure, as it appears in the Patent and Trademark Office files or records, but otherwise reserves all copyright rights whatsoever.
The present invention comprises a new and distinct pineapple variety of Ananas comosus, hereinafter referred to as the variety named ‘Vintage Ruby’. The variety has been developed by sexual crossing between plants, selected by mass selection of the hybrids. The process started during the year 2008, using the variety A. comosus var. comosus ‘Morada’ cultivar (non-patented) as parent, brought from Kunia, Hi. This plant was crossed with the variety ‘MD-2’ (non-patented), commercially known as ‘Del Monte Gold’. The pineapple plant ‘Vintage Ruby’ was developed through sexual hybridization (hand-pollination) at Buenos Aires, Puntarenas, Costa Rica. The development process took eleven consecutive years of hybridization, planting and selection. The new variety ‘Vintage Ruby’ was the final result of a back-cross of one selected plant of the F1, with a selected plant of ‘MD-2’, to achieve the combination of characters of interest to consider ‘Vintage Ruby’ as a variety of commercial potential.
The main objective of the hybridization program was to obtain a pineapple plant with an attractive fruit in shape and size, plus excellent organoleptic traits that satisfy market requirements. Finally, the new cultivar was developed for the purpose of seeking a red or dark purple fruit shell, characteristic that distinguish it from its parental materials. The new cultivar was effectively asexually reproduced true-to-type at Buenos Aires, Puntarenas, Costa Rica via leaf crown budding technique.
The invention is related to a new and distinct pineapple variety of the Bromeliaceae family, which was derived from a backcross (BC) between the ‘MD-2’ and the F1 (‘MD-2’ X ‘Morada’ cultivar), through hand-pollination and mass selection process during eleven years.
The selected hybrid is distinct in most characteristics to the ‘MD-2’ parent and was more alike to the F1 parent. The color of the fruit's shell at the immature state is deep dark purple, and at the mature state is bright reddish/purple. The selected backcross 1 (BC1) plant's fruit has an internal quality and pulp color similar to the ‘MD-2’ fruit. The total soluble solid contents (TSS), citric acid, ascorbic acid, pulp color, and the size of the fruit are similar to the ‘MD-2’. The fruit is cylindrical to slightly conical in shape, has a very pleasant aroma, and delectable taste, similar to the ‘MD-2’. One important trait is that it exhibits the hybrid vigor, producing higher yields in comparison to its F1 parent.
The new variety is characterized by purple/brownish color in the leaves, smooth with occasional presence of spines at the tip. Leaf color is similar, but not equal to the F1 and to the original ‘Morada’ cultivar, contrasting to ‘MD-2’.
This plant does not produce slips unlike its parents, which do always produce at least one (See FIG. 1 ).
The accompanying pictures illustrate the overall appearance of the new Ananas comosus var. comosus ‘Vintage Ruby’ showing the colors as reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately described the colors of ‘Vintage Ruby’.
The foregoing and other features and advantages of the plant will be apparent from the following detailed botanical description, as illustrated in the accompanying photographs.
The new Ananus comosus cultivar ‘Vintage Ruby’ has not been observed under all possible environmental conditions. However, the plants were grown under environmental conditions and cultural practices which approximate those generally used in commercial pineapple growing operations. The phenotype of the new cultivar may vary depending on the environmental conditions such as temperature, humidity, light intensity and photoperiod without any change made to the genotype of the plant.
The aforementioned photographs, together with the following observations, measurements and values describing plants of ‘Vintage Ruby’ are based on observations made under optimally fertilized and growing conditions, in the region of Buenos Aires, Puntarenas, Costa Rica (latitude 9.148773° and longitude −83.336024°), a 350 masl, where the temperatures generally range from 14° C. to 37° C., and an annual rainfall average of 3251 mm.
The plants were developed at Buenos Aires-Puntarenas, Costa Rica.
The color terminology and designation reported here are in accordance to the Munsell Color Notation for Plants Tissues published by Munsell Color Macbeth, a division of Kollmorgen Corporation, Baltimore, Md. USA.

-
V. This plant has none or very few (1) suckers.
Summary of the special characteristics of ‘Vintage Ruby’ hybrid: the plant of ‘Vintage Ruby’ presents differences compared to its parental lines, such as:
I. Red/purple shell color with yellow pulp: the backcross between F1 and ‘MD-2’, ended up in a combination of a fruit with bright red/purple shell and yellow pulp similar to ‘MD-2’.
II. Plant with absence of slips: ‘MD-2’ variety produces between 1-3 slips per plant, and the F1 produces between 4-6 slips per plant. By comparison, ‘Vintage Ruby’ doesn't produce slips at all, which reduces cosmetic and pest problems that can be originated by the contact of the slips with the fruit.
III. The fruit presents suitable levels of brix, citric acid and ascorbic acid similar to ‘MD-2’ and far superior than the F1. As a result of the backcross process, ‘Vintage Ruby’ has a red shell color at the time of full maturity, similar to the F1; and with fruit size, pulp color, and internal quality similar to the ‘MD-2’. This combination of characteristics is important to differentiate this hybrid from its parents; as shown on Table 3, when reproduced asexually, these characteristics are stable and reproducible for successive generations.

- The pineapple variety ‘Vintage Ruby’ has a post-harvest shelf life similar to ‘MD-2’, showing similar performance in shell dehydration studies.
- ‘Vintage Ruby’ characteristics differ from other varieties in the following aspects. General characteristics of the fruit are as follows (A) a fruitlet apex which is flat; (B) the flesh density is medium; (C) the number pf fruitlets per syncarp is 120-140; (d) the fruitlet characteristics are as follows:

- I. Shell color.—Its shell color at mature and immature stages is similar to the ‘Morada’ variety.
- II. Weight and shape of fruit.—‘Vintage Ruby’ fruit weight is significantly greater than ‘Morada's’, and similar to the ‘MD-2’, and ‘Champaka’, with a cylindrical to slightly conical fruit shape.
- III. Ascorbic acid.—‘Vintage Ruby’ has a higher content of ascorbic acid than its relative A. comosus cv. ‘Morada’, but similar to ‘MD-2’ and ‘CO-2’.
- IV. Citric acid.—‘Vintage Ruby’ citric acid content is similar to ‘MD-2’.
- V. Brix.—The sugar content (measured as brix degrees) of ‘Vintage Ruby’ is similar to that found on ‘MD-2’, higher than ‘Singapore Spanish’ and somewhat lower to ‘Josephine’ variety.
- VI. Age to forcing.—‘Vintage Ruby’ is vigorous and can reach forcing plant size 7 to 8 months after planting. Although this depends on the planting material used and the desired plant weight for floral induction, under similar conditions, ‘MD-2’ which reaches an optimal forcing size 8.5 months after planting.
- VII. Leaf spines.—This characteristic is commonly used to differentiate pineapple plants from other varieties. The color of the leaf spines are as follows: Tip: pale yellow 10Y 9/1, base: pale red 2.5
R 3/8. ‘Vintage Ruby’ does not have conspicuous or regular thorns on the leaf like its parental ‘Morada’. It does have inconspicuous thorns at the leaf tips, like its parental ‘MD-2’, although ‘MD-2’ often presents irregular thorns on the edges of the leaf blade as well.
Table 3 compares some of the most important characteristics for fresh fruit versus local varieties for exportation. This chart shows comparisons between ‘Vintage Ruby’ and other varieties.
