Adele Raspberry Variety Yield and Virus Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raspberry varieties face challenges in yield, spine density, fruit color, ease of harvesting, and resistance to diseases like Raspberry Bushy Dwarf Virus, with limited options for high-quality, mid-season production suitable for fresh market demand.
Innovation Solution
The development of the new red raspberry variety 'Adele', derived from crossing 'Chilcotin' and selection 86107O58, which exhibits improved yield, reduced spine density, brighter fruit color, and resistance to Raspberry Bushy Dwarf Virus, with a semi-spine-free upright growth habit and high glossiness, making it suitable for hand-picking and fresh market consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing raspberry varieties are used for mid-season production, then they can provide some yield, but they suffer from high spine density, lower fruit quality, and susceptibility to Raspberry Bushy Dwarf Virus
Solution Approach 1:
The patent applies parameter changes by creating a new variety with modified genetic parameters that reduce spine density and increase virus resistance while maintaining or improving yield. The variety 'Adele' exhibits semi-spine-free characteristics and resistance to Raspberry Bushy Dwarf Virus, representing a change in the biological parameters of the plant to resolve the contradiction between productivity and harmful factors.
Solution Approach 2:
The patent employs composite materials by combining desirable traits from different parent varieties through controlled crossing. The variety 'Adele' is the result of crossing 'Chilcotin' and selection 86107O58, creating a composite genetic structure that integrates high yield potential with reduced spine density and virus resistance, effectively combining multiple beneficial properties into a single variety.
2Illumination intensity
If existing raspberry varieties are used, then they can produce fruit, but the fruit color is less bright and glossiness is reduced compared to variety 'Adele'
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters controlling fruit coloration and surface properties. Variety 'Adele' exhibits brighter red color and higher glossiness due to changes in pigmentation genes and cuticle properties, demonstrating how parameter changes in plant genetics can improve visual quality attributes while maintaining productivity.
3Ease of operation
If existing raspberry varieties are used for hand-picking, then harvesting can be performed, but ease of harvesting is reduced due to spine density and fruit removal difficulty
Solution Approach 1:
The patent applies parameter changes by modifying the physical parameters of the plant structure, specifically reducing spine density and altering cane architecture. Variety 'Adele' has semi-spine-free canes and fruit that are easier to remove, changing the mechanical parameters of the plant to facilitate hand-harvesting operations while maintaining high yield potential.

AI summary
A new and distinct floricane fruiting red raspberry, Rubus idaeus L., variety is described. The variety results from selection among a population of seedlings derived from controlled pollination crossing of the raspberry varieties known as ‘Chilcotin’ (not patented) and an unreleased selection with the breeder code 86107O58 (not patented). The fruit of this new variety has an attractive appearance characterized by very shiny, mid light-red fruit color. The new variety is distinguished from others by its high yields of firm and attractive conical shaped, uniform sized, large, red berries that ripen in the mid season. The plant exhibits a semi spine-free upright growth habit, of strong vigor. The new variety appears suitable for the fresh fruit market and has been named ‘Adele’.
