BeeOne Avocado Variety for Late Ripening and Long Shelf Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of avocado tree that exhibits unique fruit and tree characteristics, such as late ripening, thick skin texture, excellent pulp-to-seed ratio, and high commercial quality, which are not present in existing varieties like 'Reed' and 'Hass'.
Innovation Solution
The development of a new avocado tree variety, 'BeeOne', characterized by a chance seedling with obovate fruit shape, thick pebbled skin, and a favorable pulp-to-seed ratio, along with upright to moderately spreading tree shape, suitable for high-density planting and strong cross-pollination, which is propagated through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new avocado variety is developed with unique characteristics, then fruit quality and commercial value are improved, but breeding time and resource investment increase
Solution Approach 1:
The patent utilizes asexual reproduction through grafting to create identical copies of the original seedling tree. This allows the unique fruit quality characteristics of the single original tree to be replicated across multiple production trees without requiring lengthy selective breeding programs, thus improving fruit quality consistency while minimizing breeding time
Solution Approach 2:
The variety exhibits strong self-pollination capability and cross-pollination with A-flower types, ensuring reliable fruit set without requiring external intervention. The tree's natural reproductive mechanisms serve the variety's propagation needs, reducing the time and resources required for manual pollination and breeding management
2Duration of action of stationary object
If fruit skin thickness is increased for longer shelf-life, then storage duration is improved, but fruit size and marketability may be affected
Solution Approach 1:
The patent describes a variety where the skin thickness parameter has been optimized to achieve extended shelf-life while maintaining acceptable fruit shape. The thick skin (characteristic of the variety) provides protection and extends storage duration, while the overall obovate shape and size remain within commercially acceptable parameters through natural selection and propagation
3Productivity
If tree density is increased for higher productivity, then yield per hectare is improved, but pollination effectiveness may be reduced
Solution Approach 1:
The patent describes a variety with B-flower timing that dynamically complements A-flower varieties in the orchard. This temporal dynamic in flower opening ensures that even at high planting densities, cross-pollination between varieties with different flowering times maintains pollination effectiveness while maximizing yield per hectare
Solution Approach 2:
The variety serves multiple functions: it acts as both a productive fruit-bearing tree and a pollination partner for A-flower varieties. This multi-functionality allows high-density planting to maintain both productivity and pollination success, as the B-flower trees provide pollen for A-flower trees and vice versa

AI summary
The present invention introduces a novel and distinct variety of Persea americana Mill., named ‘BeeOne’, which emerged from a chance seedling discovered in the Western Cape of South Africa, with commendable commercial traits, including late maturation, thick green skin, and characteristics from both the Mexican and Guatemalan horticultural traits. The traits of ‘BeeOne’ have been systematically documented from 2018 to the present. Key distinguishing features of ‘BeeOne’ include its very late ripening and obovate fruit shape, which possesses a notably thick, highly pebbled skin. The fruit is dark green with a flattened base, offering an excellent shelf life and a creamy/nutty flavor profile, complemented by a favorable pulp-to-seed ratio. The tree shape of ‘BeeOne’ is characterized as upright to moderately spreading, featuring one to three central leaders, which enhances its suitability for high-density planting and interplanting alongside A-flower types, ensuring effective cross-pollination.
