Sweet Jasper Grapevine Early Ripening Uniform Berry Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new grapevine variety that is early ripening, very fertile, with attractive berries of uniform size and shape, firm with tender crunchy skin, and adaptable to various climates and growing conditions, as existing varieties do not consistently meet these criteria.
Innovation Solution
The development of the grapevine variety 'SWEET JASPER' through controlled breeding, which combines the desirable traits of early ripening, high fertility, uniform berry size and shape, attractive yellowish green color, and firm crunchy skin, achieved by crossing Vitis vinifera L. 'ARO 2117' and 'ARO 1717', and propagated through asexual methods to ensure consistent characteristics across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing grapevine varieties are used, then cultivation is straightforward, but they fail to consistently achieve early ripening, high fertility, uniform berry characteristics, and adaptability to various climates
Solution Approach 1:
The patent combines multiple desirable traits from different parent varieties into a single new variety 'SWEET JASPER'. The female parent 'ARO 2117' contributes early ripening and small seedless berries, while the male parent 'ARO 1717' contributes vigorous growth and adaptability. The breeding program merged these characteristics to create a variety that simultaneously achieves early ripening, high fertility, uniform berry size and shape, and climate adaptability.
2Productivity
If a new grapevine variety with multiple desirable traits is developed through controlled breeding, then productivity and berry quality are improved, but the breeding process and propagation requirements become more complex
Solution Approach 1:
The new variety 'SWEET JASPER' exhibits self-service characteristics through its inherent vigor and adaptability. The variety maintains strong vigorous plant growth and consistent fruit production across different climates and growing conditions without requiring intensive management interventions. The asexual propagation method ensures the variety propagates true-to-type, maintaining its desirable characteristics automatically across generations.
3Reliability
If asexual propagation is used to maintain consistent characteristics, then reliability of traits is improved, but the propagation process requires precise control and monitoring
Solution Approach 1:
The patent employs asexual propagation through bud grafting to replace the need for repeated sexual crossing and selection processes. This substitution ensures that the genetic composition remains identical across generations, maintaining the variety's desirable traits of early ripening, high fertility, and uniform berry characteristics without requiring complex breeding interventions in each generation.
