Strawberry plant named ‘Margherita’
A new and distinct short-day strawberry cultivar is provided. Attractive early-ripening substantially uniform bright red conical fruit having a firm flesh is formed in good yields. White inflorescence is formed on an early basis that is disposed at approximately the same level as the foliage. A calyx commonly is displayed that is smaller than the corolla when open. A dense upright globular growth habit is displayed.
Botanical/commercial classification: Fragaria×ananassa Duchesne/Strawberry Plant.
Varietal denomination: cv. Margherita.
BACKGROUND OF THE INVENTIONThe new and distinct short-day strawberry cultivar of the present invention was the product of a controlled breeding program that was carried out at Nova Siri (MT) Italy located at 40° 08′ 40″ N.-16° 39′ 40″ E. and 10 meters above sea level. The female parent (i.e., the seed parent) was the ‘Siris’ cultivar (non-patented in the United States and EU No. 34843) and the male parent (i.e., pollen parent) was the ‘Pajaro’ cultivar (non-patented in the United States). The parentage of the new cultivar can be summarized as follows:
‘Siris’בPajaro’.
The seeds resulting from the pollination were sown and small plants were obtained which were physically different from each other. Selective study and testing resulted in the identification of a single plant of the new cultivar.
The new cultivar initially was designated AD.09.06.
It was found that the new short-day strawberry cultivar of the present invention displays the following combination of characteristics:
-
- (a) exhibits a dense, upright generally globose growth habit,
- (b) displays on an early basis white inflorescence at approximately the same level as the foliage,
- (c) commonly displays a calyx that is generally smaller than the corolla when open, and
- (d) forms in abundance early-ripening substantially uniform large bright red conical fruit having a firm flesh.
The new cultivar of the present invention can be readily distinguished from previously known strawberry cultivars including the ‘Sabrosa’ cultivar (U.S. Plant Pat. No. 16,558) as indicated in detail hereafter.
The new cultivar possesses characteristics that commonly are sought by commercial strawberry growers. Substantially uniform firm bright red early-ripening fruit is provided in good yields. Accordingly, the new cultivar is considered to be a promising new plant introduction.
The new cultivar has been asexually reproduced by the use of stolons at Ochla, Poland located at 51° 848 N.-15° 447 E. and by in vitro tissue culture. No rooting problems were encountered. The combination of characteristics exhibited by the new plant has been found to be stable and is reliably transmitted to succeeding generations following such asexual reproduction. Accordingly, the new cultivar reproduces true-to-type manner by such asexual reproduction.
The new plant has been named ‘Margherita’.
The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this character, typical specimens of the new cultivar as well as typical specimens of the ‘Sabosa’ cultivar (U.S. Plant Pat. No. 16,558) for comparative purposes. The plants had been asexually reproduced from stolons and were planted under the cover of plastic tunnels during mid-October 2012 at Nova Siri (MT), Italy.
The described plants had been asexually reproduced by the use of stolons and were growing under the cover of plastic tunnels at Nova Siri (MT) Italy. The chart used in the identification of color is The R.H.S. Colour Chart (1995 Edition or equivalent) of The Royal Horticultural Society, London, England. Reference to common color terms is to be accorded ordinary dictionary significance.
- Botanical class: Fragaria×ananassa, Duchesne, cv. ‘Margherita’.
- Plant:
-
- Type.—Short-day.
- Configuration.—Upright, relatively dense, and generally globose.
- Vigor.—Medium strong.
- Height.—Commonly approximately 25 cm on average.
- Width.—Commonly approximately 28 on average.
- Leaflets.—Medium in size, commonly up to approximately 9.5 cm in length on average and up to approximately 8 cm in width on average; the terminal leaflet commonly is longer in length than width and commonly is approximately 8.5 cm in length and approximately 7 cm in width, possess a concave cross section, a serrate to crenate margin, and an acute base; blistering commonly is absent; the glossiness on the upper surface is medium; and variegated coloration commonly is absent with the upper surface coloration commonly being near Green Group 141A to 141B and the under surface commonly being near Green Group 141C to 143D. Such coloration commonly is darker than that of the ‘Sabrosa’ cultivar.
- Stolons.—Numerous in quantity, medium pubescence in density, commonly near Green Group 141A to 142B in coloration, and commonly bear some weak to medium anthocyanin coloration commonly near Red-Purple Group 65C to 65D. Stolons commonly are produced somewhat more numerously than the ‘Sabrosa’ cultivar (i.e., approximately 30 to 35% more) with anthocyanin coloration commonly being absent on the stolons of the ‘Sabrosa’ cultivar.
- Petioles.—Commonly approximately 17 to 21 cm in length on average, near Green Group 149A in coloration, and commonly bear horizontally disposed fine pubescence.
- Stipules.—Larger than those of the ‘Sabrosa’ cultivar as illustrated in
FIGS. 12 and 13 , and commonly bear some anthocyanin coloration unlike the stipules of the ‘Sabrosa’ cultivar where anthocyanin coloration was not observed.
-
- Inflorescence:
-
- Flowering time.—Early.
- Flower number.—Medium, commonly 4 or 5.
- Pedicel hairs.—Pubescence generally disposed upwards.
- Size.—Large, with primary flowers commonly being approximately 2.8 cm in diameter on average, and secondary flowers commonly being approximately 2.5 cm in diameter on average.
- Petals.—Overlapping, commonly number approximately 5 to 8 on average, commonly greater in width than length, and near White Group 155B to 155C in coloration.
- Anthers.—Commonly number approximately 25 on average and disposed slightly above the stamens. The plant is self fertile.
- Sepals.—Generally lanceolate in configuration, outwardly disposed, commonly number approximately 10 to 14 which can be compared to approximately 10 to 12 for the ‘Sabrosa’ cultivar, commonly approximately 4 to 7 mm in length on average and approximately 2 to 3 mm in width on average at the broadest point, unlike the ‘Sabrosa’ cultivar the diameter of the open calyx commonly is generally less than that of the corolla (as illustrated in
FIG. 15 ), and the coloration is commonly near Yellow-Green Group 144B to 144C when viewed from below the open corolla.
-
- Fruit:
-
- Bearing.—Non-remontant.
- Timing.—Early-fruiting commonly with approximately 30 to 35 days from first blooming to first fruit ripening. This can be compared to approximately 35 to 40 days between first blooming and first fruit ripening for the ‘Sabrosa’ cultivar.
- Shape.—Generally conical in configuration, and substantially uniform with commonly only a slight shape difference between terminal and other fruit.
- Size.—Large, with the primary fruit commonly being approximately 5 to 5.5 cm in length and width at the broadest point.
- Surface.—Generally smooth with strong glossiness.
- External color.—Substantially uniform and commonly near Red Group 40A to Red Group 44B.
- Internal color.—Medium red, and commonly near Red Group 40A to 40B.
- Firmness.—Good, with medium flesh firmness.
- Cavity.—Very small or absent fruit cavity (as illustrated in
FIG. 6 ). - Achenes.—Located below the fruit surface and cover nearly the entire fruit surface commonly with only a narrow band of 3 to 4 mm where achenes are absent, and commonly near Orange-Red Group 33B to 33C in coloration.
- Calyx.—Commonly substantially level at end of fruit with strong adherence to fruit.
- Peduncle.—Approximately 10 to 12 cm in length on average for primary and secondary fruit, approximately 1.5 mm in diameter on average, commonly near Yellow-Green Group 149A in coloration.
- Pedicel.—Commonly with pubescence extending slightly outwards.
-
Hereafter, comparative fruit data is provided for the new ‘Margherita’ cultivar and the ‘Sabrosa’ cultivar. On Oct. 15, 2012 plots of fifty (50) plants of each cultivar were planted in four (4) replications at Nova Siri (MT), Italy. The plants had been asexually reproduced by the use of stolons and were growing under the cover of plastic tunnels. The fruit was evaluated and compared during 2013 on the dates indicated. Average data is presented.
Plants of the new ‘Margherita’ cultivar have not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
