plant named ‘Eves Delight 2’

Abstract

A new cultivar of Fragaria plant named ‘Eves Delight 2’ that is characterized by its semi-upright growth habit, its conical shaped berries that are uniformly large in size, its berries with very firm skin and firm flesh, its berries that contain very high sugars and a sweet pleasant flavor, its berries that are glossy, pale red in color and retain color throughout production, and its vigorous growth with substantial fruit yields of marketable quality fruit early in season.

Description

Botanical classification: Fragaria x ananassa.

Variety denomination ‘Eves Delight 2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Fragaria, botanically known as Fragaria x ananassa and will be referred to hereafter by its cultivar name, ‘Eves Delight 2’. ‘Eves Delight 2’ is a day neutral strawberry plant primarily adapted to the climate and growing conditions of the United Kingdom and other regions of similar climate and day length.

The new cultivar was derived from an ongoing breeding program conducted by the Inventor at a farm in Faversham, Kent, United Kingdom. The objective of the breeding program was to develop a new cultivar of Fragaria with high fruit yields, consistent cropping, good disease tolerance, and large, uniform fruit with firm skins, low acid content, and good eating quality. ‘Eves Delight 2’ arose from a controlled cross made by the Inventor in 2013 between an unpatented selection from the Inventor's breeding program, designated as accession number EZ05 as the female parent and an unpatented selection from the Inventor's breeding program, designated as accession number GB96 as the male parent. ‘Eves Delight 2’ was selected as a single unique plant in the summer of 2014 from amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by rooting stolons in Faversham, Kent, United Kingdom in 2014. Asexual propagation by rooting of stolons and tissue culture using meristematic tissue 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 represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Eves Delight 2’ as a new and unique cultivar of Fragaria.

• • 1. ‘Eves Delight 2’ exhibits a semi-upright growth habit.
  • 2. ‘Eves Delight 2’ exhibits conical shaped berries that are uniformly large in size.
  • 3. ‘Eves Delight 2’ exhibits berries with very firm skin and firm flesh.
  • 4. ‘Eves Delight 2’ produces berries that contain very high sugar levels and a sweet pleasant flavor.
  • 5. ‘Eves Delight 2’ exhibits berries that are glossy, pale red in color and retain its color throughout production.
  • 6. ‘Eves Delight 2’ exhibits vigorous growth with substantial fruit yields of marketable quality early in season.

The female parent of ‘Eves Delight 2’ differs from ‘Eves Delight 2’ in having berries that have a darker skin, flesh and core color, a denser plant canopy and smaller fruit size. The male parent of ‘Eves Delight 2’ differs from ‘Eves Delight 2’ in having darker leaves with a greater affinity for blistering, lower fruit yield, and fruit that is shorter in length and more rounded in overall shape.

‘Eves Delight 2’ can most closely be compared to the cultivars ‘Sweet Eve’ (U.S. Plant Pat. No. 21,380) and ‘Eves Delight’ (U.S. Plant Pat. No. 21,381). ‘Sweet Eve’ is similar to ‘Eves Delight 2’ in having a conical berry shape and a mostly re-curved calyx position relative to the fruit. ‘Sweet Eve’ differs from ‘Eves Delight 2’ in exhibiting a lower percentage of class I fruit, a softer berry flesh that results in a shorter shelf life, and trusses that are shorter in length.

The plant vigor of ‘Sweet Eve’ and ‘Eves Delight 2’ is different in multiple ways. ‘Eves Delight 2’ is generally taller in height than ‘Sweet Eve’, has a less compact and dense canopy with a slightly larger leaf size, and petiole and petiolule lengths that are considerably longer.

The leaf shape is more elongated in ‘Eves Delight 2’ than in ‘Sweet Eve’ as the ‘Eves Delight 2’ leaves have a slightly greater length to width ratio. On average, ‘Eves Delight 2’ has more serrations per leaf than ‘Sweet Eve’. The majority of leaves for ‘Eves Delight 2’ and ‘Sweet Eve’ are concave in their general curvature and while both exhibit blistering, it is far more prominent in ‘Sweet Eve’. ‘Eves Delight 2’ leaves are generally much paler green in color, with this difference becoming more apparent as the season progresses.

Despite a considerably longer truss length in ‘Eves Delight 2’ than ‘Sweet Eve’, both varieties display their inflorescences in a similar way with the majority presented level with the plant canopy.

The average corolla and calyx size for ‘Sweet Eve’ is larger than ‘Eves Delight 2’. Both display a petal shape of a rounded base and apex with similar, if not slightly more petals in ‘Eves Delight 2’.

The average berry size of ‘Eves Delight 2’ is larger than that of ‘Sweet Eve’ with better fruit shape uniformity also observed in ‘Eves Delight 2’. Both varieties exhibit conical shaped berries that are glossy. While the color of both varieties is uniformly maintained throughout the season, the fruit of ‘Eves Delight 2’ is considerably paler in color than ‘Sweet Eve’. The number of achenes is generally greater in ‘Sweet Eve’ compared to ‘Eves Delight 2’ and the achene position differs slightly. With ‘Eves Delight 2’, the majority of the achenes are indented whereas with ‘Sweet Eve’ they are split between those that are even with the fruit surface and those that are indented. There is a white band void of achenes at the top of the berry clearly present in ‘Sweet Eve’ that is absent or very narrow in ‘Eves Delight 2’. Both ‘Eves Delight 2’ and ‘Sweet Eve’ produce berries that are high in Brix and reasonably low in acidity.

‘Eve's Delight’ is similar to ‘Eves Delight 2’ in fruit color. ‘Eve's Delight’ differs from ‘Eves Delight 2’ in cropping later in the season, having fruit that the shape differs more between primary and secondary fruit, lower average fruit yield, and leaves that are darker green in color.
