Blueberry Cultivar Named 'Echo'

Abstract

Echo is a new and distinct repeat flowering, ornamental blueberry (Vaccinium section Cyanococcus L.) cultivar that originated from seed produced from the cross of the female blueberry plant Perpetua (U.S. Plant Pat. No. 24,209) and the male blueberry plant ORUS 55-1 (unpatented). Echo is a blueberry clone distinguished by its ornamental characteristics that include a spreading bush habit with glossy leaves, repeat flowering and fruiting, and small, mild flavored dark blue fruit.

Claims

1. A new and distinct cultivar of blueberry plant, substantially as illustrated and described, characterized by its ability to flower on new growth without any chilling; attractive combination of flowers and fruit in late summer and fall; dark green, glossy, attractive leaves; edible, dark blue fruit; and vigorous and compact, spreading, plant habit.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0006] This new blueberry plant is illustrated by the accompanying color photographs that show typical specimens of the flower clusters in bloom (FIG. 1), ripe fruit on a four-year-old plant (FIG. 2), and the entire plant with a ripening crop in late August (2.sup.nd crop) (FIG. 3); the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

Color designations, color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. Echo has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart. London (R.H.S.) (5.sup.th edition, 2007).

[0012] Resistance to diseases and insects: In a minimal spray program with dormant sprays only, Echo has had no fungal or bacterial disease symptoms and no indication of problems with gall midge. Echo plants have not yet shown symptoms or tested positive for Blueberry shock virus; if it was an extremely susceptible (e.g. Bluegold (unpatented)), it would be showing symptoms and testing positive after 5 years in the field, however, it is too soon to characterize it as slow to get the virus.

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

[0013] Echo differs from the female parent Perpetua (U.S. Plant Pat. No. 24,209), which is also the closest comparable commercial cultivar, in that its fruit appear longer as they have a greater length to width ratio, the fruit are a much darker violet-blue and the plants are broader and more spreading than upright with grey-red vs olive-green bark and the leaves are narrower and smaller.

[0014] Echo differs from the male parent ORUS 55-1 (unpatented) in that the fruit are much more blue than black and the plant is more compact with glossy leaves.
