plant named ‘Verity’

Abstract

A new and distinct day-neutral cultivar of strawberry plant named ‘Verity’ that is characterized by its upright dense growth habit, its ovoid shaped berries that are uniformly large in size, its berries with firm skin and juicy, soft flesh, its berries that are glossy and bright medium red in color, its vigorous growth with substantial fruit yield, its day neutral fruiting habit with mid to late season production, its good tolerance to fruit skin damage caused by rain fall, its moderate petiole pubescence, and its tolerance to Podosphaera leucotricha (powdery mildew).

Description

Botanical classification: Fragaria×ananassa.

Variety denomination: ‘Verity’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Fragaria, botanically known as Fragaria×ananassa ‘Verity’, and will be referred to hereafter by its cultivar name, ‘Verity’. ‘Verity’ is a day-neutral strawberry primarily adapted to the climate and growing conditions of south eastern England and other regions of similar climate and day length.

The new cultivar was derived from an ongoing breeding program conducted by the Inventor at his farm in Kent, United Kingdom. ‘Verity’ arose from a controlled cross made by the Inventor in 2006 between the cultivar ‘Evita’ (U.S. Plant Pat. No. 9,091), as the female parent and an unnamed plant from the Inventors breeding program, designated as accession number ‘04AA21’ as the male parent. ‘Verity’, designated as accession number ‘06HN43’, was selected as a single unique plant in summer 2006 from amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by rooting of stolons by the Inventor in Kent, United Kingdom in 2006. Asexual propagation by rooting of stolons has shown that the unique characteristics of the new cultivar are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be characteristics of the new cultivar of strawberry. These attributes in combination distinguish ‘Verity’ as unique from all other strawberry cultivars known to the Inventor. ‘Verity’ is well adapted for the growing conditions in the United Kingdom.

• • 1. ‘Verity’ exhibits an upright dense growth habit.
  • 2. ‘Verity’ exhibits ovoid shaped berries that are uniformly large in size.
  • 3. ‘Verity’ exhibits berries with firm skin and juicy, soft flesh.
  • 4. ‘Verity’ exhibits berries that are glossy and bright medium red in color with color retained throughout production.
  • 5. ‘Verity’ exhibits vigorous growth with substantial fruit yields.
  • 6. ‘Verity’ exhibits a day neutral fruiting habit with mid to late season production.
  • 7. ‘Verity’ exhibits tolerance to fruit skin damage caused by rainfall.
  • 8. ‘Verity’ exhibits moderate petiole pubescence.
  • 9. ‘Verity’ exhibits tolerance to Podosphaera leucotricha (powdery mildew).

‘Evita’, the female parent of ‘Verity’, differs from ‘Verity’ in having berries that are conical in shape, lower in acidity, and darker red in color. ‘04AA21’, the male parent of ‘Verity’, differs from ‘Verity’, in being highly susceptible to Phytophthora cactorum and in having berries that are pale red in color.

‘Verity’ can be most closely compared to the cultivar ‘Sweet Eve’ (U.S. Plant Pat. No. 21,380) with the following comparison characteristics observed under United Kingdom growing conditions. ‘Verity’ produces a larger fruit size than ‘Sweet Eve’ has a fruit shape that is slightly more ovoid to that of ‘Sweet Eve’, however they are both uniform, a fruit skin similarly firm but juicier fruit than that of ‘Sweet Eve’, an increased flower truss length than that of ‘Sweet Eve’, and a flat calyx position relative to the fruit that is significantly larger than that of ‘Sweet Eve’. Furthermore, the fruit of ‘Verity’ has a better shelf life than that of ‘Sweet Eve’. Finally, ‘Verity’ possesses a refreshing soft and juicy fruit texture compared to the fruit of ‘Sweet Eve’.

‘Verity’ plants exhibit a more vigorous growth habit than that of ‘Sweet Eve’ and when it is grown in the United Kingdom, the plant size is significantly greater than ‘Sweet Eve’. The leaf size of ‘Verity’ is medium, but larger than that of ‘Sweet Eve’, and the leaflets are generally round and almost as wide as long.

The petiole and petiolule lengths of ‘Verity’ are greater than that of ‘Sweet Eve’. Some hair is present on ‘Verity’ at the base of the petiole and close to the stipules but pubescence is more moderate than that of ‘Sweet Eve’. The petiolule pubescence of ‘Verity’ is moderate, but still considerably less than that of ‘Sweet Eve’.

The leaflets of ‘Verity’ typically possess a slightly round (obtuse) base and tip; however, the leaflets are not symmetrical. In fact, the leaflets of ‘Verity’ express a very distinctive architecture wherein the distance from the petiolule to the first serration is significantly longer on one side compared to the other (approximately 20%). The serrations express slightly pointed to slightly rounded tips with the leaflets of ‘Verity’ plants possessing a slightly smaller number of serrations per leaf than that of ‘Sweet Eve’. The most outstanding difference between the two varieties is expressed in the leaf architecture, where the leaflets of ‘Verity’ are flat or slightly convex, whereas the leaflets of ‘Sweet Eve’ express an upwards curving feature. Many leaflets of ‘Verity’ exhibit slight to moderate puckering/blistering, a feature that is visible on more mature leaves.

‘Verity’ flower trusses tend to grow within the foliage that do not stand out of the leaf canopy, however approximately 50% of the overall trusses are exposed over the leaf canopy. These exposed fruit trusses, when loaded with fruit, tend to protrude to the sides of the plant between the leaves rather than expressing a totally upwards direction. The presence of a bract can be seen on 80% of the flower trusses from early developmental stage, which progresses into a typical leaflet as the truss matures and fruit develops.

The primary flowers of ‘Verity’ are generally larger than those of ‘Sweet Eve’. Petal numbers of ‘Verity’ are similar to ‘Sweet Eve’. The calyx of ‘Verity’ is significantly larger than that of ‘Sweet Eve’. The calyxes of ‘Verity’ are typically flat touching the shoulders of the fruit, however some are recurving expressing a very narrow fruit neck at the top of the berry.

The berries of ‘Verity’ are large in size with a shape that is predominantly ovoid with broad shoulders. When grown in the United Kingdom, the fruit of ‘Verity’ has an even uniform shape without a neck, feature that is very prominent in the fruit of ‘Sweet Eve’.

‘Verity’ berries are darker than those of ‘Sweet Eve’. During the summer season, the fruit of ‘Verity’ retains its bright red color and appears to be unaffected by the higher seasonal temperatures. ‘Verity’ has shown to exhibit significant tolerance to the effect of rain splitting the fruit skin.

The achenes of ‘Verity’ berries are characterized as being generally even to slightly indented into the surface of the fruit, however, this indentation is less dramatic when compared to the achenes of ‘Sweet Eve’. ‘Verity’ berries generally contain fewer achenes than those of ‘Sweet Eve’.

The berries of ‘Verity’ are noticeably juicier than ‘Sweet Eve’ throughout the cropping season with a pleasant combination of flavor, sugar, and low acid levels. The berry skin of ‘Verity’ is firmer than that of ‘Sweet Eve’ and resists bruising better during rubbing than the latter. The fruit flesh of ‘Verity’ is less firm than that of ‘Sweet Eve’ resulting in a soft and juicy texture and a nice eating experience.
