Echo Blueberry Repeat Flowering Hybrid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a blueberry cultivar that exhibits repeat flowering and fruiting, glossy leaves, and produces small, mild-flavored dark blue fruit, while also being vigorous and spreading, which are characteristics not adequately met by existing blueberry varieties.
Innovation Solution
The development of the 'Echo' blueberry cultivar, resulting from the cross of 'Perpetua' and ORUS 55-1, which features repeat flowering on overwintered canes and new growth, attractive flower and fruit combination in late summer and fall, green glossy leaves, and a vigorous spreading habit, and is stable through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If blueberry plants are bred for repeat flowering and fruiting, then flowering frequency and crop production are improved, but plant vigor and growth rate may deteriorate
Solution Approach 1:
The invention changes the physiological parameters of the blueberry plant by selecting for specific genetic traits that enable repeat flowering. The cultivar 'Echo' was developed through controlled crossing and selection to achieve multiple flowering cycles per season while maintaining plant health, representing a parameter change in flowering frequency from once to multiple times annually
2Ease of manufacture
If blueberry plants are selected for glossy leaves and ornamental characteristics, then aesthetic value is improved, but fruit size and yield may deteriorate
Solution Approach 1:
The invention applies local quality by enhancing specific traits (glossy leaves, compact habit) in certain parts of the plant while maintaining adequate fruit production. The cultivar 'Echo' exhibits glossy foliage and attractive growth habit in the vegetative portions while still producing edible dark blue fruit, demonstrating that aesthetic qualities can be localized without completely sacrificing productivity
3Adaptability or versatility
If blueberry plants are bred for intermediate characteristics between V. corymbosum and V. angustifolium, then adaptability and hardiness are improved, but fruit size uniformity may deteriorate
Solution Approach 1:
The invention uses composite materials by creating a hybrid genotype that combines genetic material from two different blueberry species (V. corymbosum and V. angustifolium). The cultivar 'Echo' possesses intermediate characteristics including leaf shape, plant hardiness, and adaptability, representing a composite genetic structure that merges traits from both parent species to achieve balanced performance

AI summary
‘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.
