Sunect30 Nectarine Tree Early Ripening and Fruit Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of nectarine tree that combines early ripening, large fruit size, sweet subacid flavor, firm white flesh, and showy flowers, while also offering improved ripening timing and flowering characteristics compared to existing varieties.
Innovation Solution
The development of the Prunus persica var. nucipersica cv. 'Sunect30' through hybridization, characterized by early ripening, large circular fruit with sweet subacid flavor, firm white flesh, and showy flowers, achieved through asexual propagation by dormant grafting, which distinguishes it from its parent varieties in ripening time, flowering timing, and fruit size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If early ripening is achieved, then harvest time is improved, but fruit size and flavor quality may be compromised
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific genetic combinations that simultaneously control ripening timing and fruit development. The variety 'Sunect30' was developed through controlled hybridization of selected parent varieties, adjusting genetic parameters to achieve early ripening (15-20 days after petal fall) while maintaining large fruit size (150-200g) and desirable flavor characteristics.
2Weight of moving object
If large fruit size is achieved, then yield quality is improved, but ripening time may be delayed
Solution Approach 1:
The breeding program utilized parameter changes by evaluating and selecting parent varieties with specific genetic traits for fruit size and ripening timing. Through controlled crosses and multiple generations of selection, the variety achieved large fruit size (150-200g) while maintaining early ripening characteristics, demonstrating that these parameters can be simultaneously optimized through genetic parameter adjustment.
3Temperature
If sweet subacid flavor is achieved, then fruit quality is improved, but acidity balance may be difficult to control
Solution Approach 1:
The patent applies parameter changes in flavor development by selecting parent varieties with specific sugar-to-acid ratios and flavor profiles. The variety 'Sunect30' was bred to achieve a Brix:acid ratio of 28, creating a sweet subacid flavor characteristic. This involved adjusting genetic parameters related to sugar accumulation and acid metabolism to achieve the desired flavor balance.
4Illumination intensity
If showy flowers are achieved, then aesthetic quality is improved, but flowering time may be altered
Solution Approach 1:
The breeding program applied parameter changes to flower characteristics by selecting parents with desirable flower traits and controlling flowering timing. The variety 'Sunect30' was developed to produce showy flowers that bloom 12 days earlier than the seed parent variety, achieving both aesthetic quality and early flowering through genetic parameter adjustment.
