Olea europaea ASKAL Olive Tree Breeding for Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing olive tree varieties lack vigorous growth, high fruit yield, resistance to Spilocaea oleagina, and optimal oil production and taste characteristics simultaneously.
Innovation Solution
The development of the Olea europaea 'ASKAL' variety through controlled breeding, combining traits such as vigorous growth, high fruit yield, resistance to Spilocaea oleagina, and desirable oil and taste profiles, achieved through asexual propagation of cuttings from 'BARNEA' and 'MANZANILLO' parents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing olive tree varieties are used, then cultivation is maintained with known characteristics, but vigorous growth and high fruit yield are not achieved simultaneously
Solution Approach 1:
The patent combines desirable traits from two parent varieties (Barnea and Manzanillo) through controlled cross-breeding to create a new variety that simultaneously achieves vigorous growth and high fruit yield. The resulting tree merges the growth characteristics of one parent with the productivity of the other, resolving the contradiction between these two traits.
Solution Approach 2:
The patent modifies genetic parameters through selective breeding to change the growth and yield characteristics of olive trees. By altering the genetic composition through cross-breeding and selecting specific progeny, the variety achieves optimized growth vigor and fruit yield that differ from the parental varieties.
2Reliability
If existing olive tree varieties are used, then cultivation is maintained, but resistance to Spilocaea oleagina is not achieved
Solution Approach 1:
The patent merges disease resistance traits from the Barnea parent with the high fruit yield characteristics of the Manzanillo parent. The resulting Askal variety incorporates the resistance to Spilocaea oleagina from one parent while maintaining the high productivity of the other, achieving both reliability and productivity.
3Quantity of substance
If existing olive tree varieties are used, then cultivation is maintained, but optimal oil production and taste characteristics are not achieved simultaneously
Solution Approach 1:
The patent changes the chemical composition parameters of the olive fruit through selective breeding. By selecting progeny with desired oil content and taste characteristics, the variety achieves optimized polyphenol content, oleic acid composition, and flavor profile that balance quantity and quality of oil production.
