Solution Overview

Problem

There is a need for a nectarine tree variety that produces high-quality, firm, and early-season fruit with specific characteristics such as white flesh, attractive coloration, and resistance to chilling units, which existing varieties like 'Flordaking' and 'TexKing' do not fully meet.

Innovation Solution

The 'Smooth Delight One' nectarine tree, developed through controlled crosses at Texas A & M University, exhibits exceptional characteristics including early ripening, firmness, and attractive coloration, requiring 350 to 400 chilling units for dormancy, and is propagated using virus-free Nemaguard rootstock, ensuring consistent fruit quality and commercial viability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If existing nectarine varieties like 'Flordaking' and 'TexKing' are used, then commercial fruit production is achieved, but early season ripening with white flesh and firm texture is not obtained

Engineering Contradiction:

Improveripening timeVSAvoidfruit quality consistency

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent applies parameter changes by selectively breeding for specific genetic traits that control ripening time, flesh color, and firmness. The 'Smooth Delight One' variety was developed through controlled crosses and selection to achieve early season ripening (5-7 days after 'Flordaking'), white flesh color, and firm texture while maintaining commercial viability. This represents a fundamental change in the genetic parameters of the nectarine variety.

2Productivity

If nectarine varieties with early season ripening are developed, then market timing advantage is achieved, but chilling unit requirements become more specific and restrictive

Engineering Contradiction:

Improvecommercial harvest timingVSAvoidchilling unit flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by specifying precise chilling unit requirements (350-400 units) tailored to the specific genetic characteristics of the 'Smooth Delight One' variety. This localized approach ensures that the variety receives the exact amount of winter dormancy needed to break bud and initiate flowering at the optimal time for early season fruit production, rather than using a broad range of chilling requirements.

Inventive Principle:

Principle #3Local quality

3Strength

If nectarine fruit is bred for firmness and early ripening, then shipping quality is improved, but flesh color becomes less attractive (white instead of colored)

Engineering Contradiction:

Improvefruit firmnessVSAvoidflesh coloration

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The patent applies partial or excessive action by emphasizing and exaggerating the early ripening and firmness traits to an extreme degree, accepting that this results in white flesh color rather than traditional colored flesh. The variety prioritizes these partial traits (early ripening and firmness) over the conventional trait of colored flesh, creating a specialized variety optimized for specific market niches that value these characteristics.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Disclosed is a new variety of Prunus persica named ‘Smooth Delight One’. This new variety, which requires 350-400 chilling units of dormancy, is considered to be a nectarine tree of early season maturity, ripens in early to mid-May in the medium chill zone of Texas, which produces white fleshed sub acid fruit that are very firm, attractively colored, and suitable for both local and regional markets.
