Abstract

A Nordic-type strawberry variety named "Chambly" combines the characteristics of cold-hardiness, adaptability to various soil conditions, vigor and strength, absence of suckering and its high yield of firm, deep red fruit with raised neck, elevated calyx and uniform well-colored flesh. Chambly yields strawberries characterized by an excellent taste (slightly sugary), a very fresh appearance and appealing texture, with a real strawberry aroma and no noticeable aftertaste.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinctive cultivar of strawberry plant named Chambly. This cultivar belongs to the genus Fragaria, whose fruits are juicy edible and usually red, cultivated for culinary purposes.
Species of strawberry plants vary in color, size, shape, acidity, and other commercially important and botanically significant characteristics. Strawberries frequently bear flowers and fruit simultaneously, and fruit tends to ripen randomly on the stems.
ORIGIN OF THE VARIETY
The new cultivar of the present invention was developed in L'Acadie, Quebec from a cross between "Sparkle" and "Honeoye". "Sparkle", a previously popular commercial cultivar in eastern Canada, is noted for its high fruit flavor (Craig, D. L., 1979, Culture du fraisier dans l'est du Canada, Agriculture Canada, Publ. 1585). "Honeoye" is a high-yielding cultivar with large fruit size well-adapted to the northeast (Estabrooks and Luffman, 1989, Strawberry cultivar evaluatin in New Brunswick, Canada, Adv. Strawberry Production, 8: 58-61). "Chambly" has been tested at Agriculture Canada, L'Acadie, Quebec, since 1984. L'Acadie is located 35 km south of Montreal (45°) at an elevation of about 46 m above seal level. Climate at L'Acadie is charactrerized by low temperatures in winter (below -25° C.), cool, humid conditions in spring, and warm, humid conditions (25° to 35° C., 70% relative humidity) in summer.
`Chambly` is a result of a cross between `Sparkle`×`Honeoye`. The seed parent, `Sparkle` was a product of `Fairfax` (from `Royal Sovereign`×`Howard 17`)×`Aberdeen`. The pollen parent `Honeoye` was a product of `Vibrant` (from `Sparkle`×`Valentine`)×`Holiday` (from `NY844`×`Raritan`).
A new variety was originated from a cross made in a controlled breeding program in St-Jean-sur-Richelieu, Quebec. The straberry variety of the present invention, `Chambly` was discovered and selected as a plant within the progeny of the stated cross in a controlled environment in St-Jean-sur-Richelieu, Quebec. Asexual reproduction of the new variety, as performed at St-Jean-sur-Richelieu in the greenhouse has demonstrated that the combination of characteristics as herein disclosed for the new variety are firmly fixed and are retained through successive generations of asexual reproduction.
This new cultivar can be asexually reproduced either by tip-cutting or tissue culturing. It can also be sexually reproduced such as by seed propagation.

FIG. 9 is a close-up view of the mature fruit of the variety grown in a field.
FIG. 10 is a close-up view of the leaves of the variety grown in a field.
DESCRIPTION OF THE VARIETY
The cultivar of the present invention is the first June-bearing strawberry cultivar (Fragaria×ananassa Duch.) bred specifically for southern Quebec conditions. This cultivar was released because of its high yields of firm, deep red fruit with raised neck, elevated calyx, and uniform well-colored flesh. Therefore, it is recommended for fresh market and processing.
Chambly adapts to various soils, but prefers neutral (approximately pH 6.8) to acid soil.
"Chambly" plants are of low vigor (Table 1), medium in size, with four to six inflorescences per plant, and can tolerate winter temperatures below -25° C. (with 10 cm of straw mulch cover).

The leaves, when fully developed, have a dark green color, corresponding to color 7.5 GY 3/4 of the Munsell Book Colour Chart and are three-lobed. Leaflets are slightly folded, medium size, obovate to spherical, with sharp serrations.
Petioles are moderately long and slightly drooping. Plants have a sparse appearance and have an average height lower than other strawberry plant variety (FIG. 1). The "Chambly" strawberry plant of the present invention has an average height of about 9 inches and an average width of about 20 inches, whereas the "Oka" strawberry plant has an average height of about 10 inches and an average width of about 24 inches. The lower the strawberry plant is, the more the fruits are exposed to sunrays which accelerates the maturity process of the fruit.
The plant stems are hairy and have yellow/green color corresponding to color 5GY 6/8 of the Munsell Book Colour Chart.
The plants showns in the appended FIGS. 1 to 6 have been grown in a greenhouse with clear glass windows with a sun filter curtain which blocks 60% of the sunrays (Cravo Equipment Ltd., Brantford, Ontario, Canada N3T 5L4). The plants have been grown with a sixteen (16) hour photoperiod/day. Sodium high presure lamp of 400 W are used when the intensity of the sunrays is too low. The temperature inside the greenhouse was 20° C. with 50% RH (relative humidity). It should be appreciated that "Chambly" fruits from "Chambly" plants grown outside are bigger and of more reddish color than the fruits matured in a greenhouse.
The color evaluations described in FIGS. 1 to 6 were made in St-Jean, Quebec, Canada, on the morning of Mar. 13, 1992, at 11:45 AM in a greenhouse. Viewing was effected in filtered sunlight through a 60% sunblock curtain (Cravo Equipment Ltd.), under dry cool conditions of a cloudy day with good visibility and a temperature of about -12° C.
The color evaluations described in FIGS. 8 to 10 were made in Lavaltrie, Quebec, Canada, on the morning of Jul. 7, 1992, at 9:30 AM in a strawberry field. Viewing was effected in direct sunlight under dry cool conditions of a cloudy day with good visibility and a temperature of about 60° F.
As shown in Table 3 below chemical analyses revealed substantial differences between "Chambly" and typical cultivated strawberry varieties. These analyses involved comparisons of pH, Brix value (percent of soluble solids), acidity (percent of citric acid found in the strawberries) and humitidy (percent of moisture).

One of the major soluble components of strawberries and other soft fruit is its sugar. The sugar-to-acid ratio is important in determining flavor and commercial acceptability. Sensory evaluations indicated that Chambly yields berries were characterized by an excellent taste (slightly sugary). Fruit flavor (sweetness) is similar to that of "Bounty" and "Sparkle" (Table 1). There is no noticeable aftertaste, and the fruits has real strawberry aroma. It has also a very fresh appearnace and appealing texture.
Fruits are firm, similar to "Kent", and can be decapped as easily as "Glooscap". The calyx does not separate from the fruit at harvest time. Percent juice lost after thawing did not differ significantly (P=0.05, n=8) among cultivars and ranged from 42% to 53%. "Chambly" has outyielded "Bouty", "Honeoye", "Redcoat", and "Sparkle" in our trials (Table 2). Plants are partially tolerant of the herbicide terbacil [5-chloro-3-(1,1-dimethylethyl)-6-methyl-2,4(1H, 3H)pyrimidine-dione]. No symptoms of powdery mildew (Sphaerotheca macularis Walls ex Fr.), leaf scorch (Diplocarpon carlina Ell. and Ev.), or leaf blight (Dendrophoma obscurans Ell. and Ev.) were observed during the course of its evaluation (Table 2).
Inflorescences are held erect on long, moderately thick peduncles during bloom, becoming arched (semi-erect) as the fruit mature. Inflorescences generally have 10 to 20 flowers (FIG. 5).
Inflorescences of Chambly are produced from June until September in northern temperate climates. Fruits ripen from June to late September in this zone.
The variety should be planted in sunny and dry locations spaced about 10 inches apart. Chambly is useful for home gardens, as well as "pick-your-own" and contract growing. After harvesting, all twigs that produced fruit, i.e., those that are two years old, should be pruned. In addition, side branches should be pruned on one year-old twigs.
The strawberry variety of the present invention, `Chambly`, requires a short day length of less than 10 hours and low temperature (>0° C. for at least 45 days) to induce flowering.
Table 4 compares the flavor and texture attributes of the `Chambly` cultivar with six other strawberry cultivars.
