Everbearing Raspberry Variety for Heat-Tolerant Fruit Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing raspberry varieties face challenges in adapting to specific climate zones, particularly in regions with summer temperatures above 95°F (35°C) and varying irrigation needs, with limited drought tolerance, and exhibit varying fruit and leaf characteristics that differentiate them from 'PS-12.082-54'.
Innovation Solution
A new raspberry variety 'PS-12.082-54' is developed through controlled crossbreeding, exhibiting unique traits such as strong yellow-green prickles, high fruit yield, and strong orange-yellow fruit, adapted to central California's climate and requiring frequent irrigation, with specific characteristics distinguishing it from other varieties like 'MAJESTIC' and its parents 'BOUNTIFUL' and 'PARAGON'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If raspberry varieties are grown in regions with summer temperatures at or above 95°F (35°C), then fruit production continues, but fruit and young leaves suffer damage
Solution Approach 1:
The patent describes a raspberry variety bred with specific genetic parameters that enable tolerance to high summer temperatures. The variety was developed through controlled crossbreeding to select for heat tolerance while maintaining fruit production capability in USDA zones 7b-9b, where summer temperatures reach 95°F or higher.
2Reliability
If raspberry varieties require frequent irrigation to maintain proper plant health, then plant health is maintained, but drought tolerance is limited
Solution Approach 1:
The patent describes a raspberry variety with specific physiological parameters that prioritize consistent plant health through regular irrigation. The variety was bred to maintain optimal growth and fruit production under irrigated conditions in central California, with documented requirements for frequent irrigation to prevent stress.
3Productivity
If raspberry varieties are bred for high fruit yield, then productivity increases, but adaptation to specific climate zones becomes more challenging
Solution Approach 1:
The patent describes a raspberry variety specifically adapted to central California's Mediterranean climate with hot summers and mild winters. The breeding program targeted local environmental conditions including temperature ranges, irrigation availability, and soil types to optimize both yield and climate adaptation simultaneously.
Solution Approach 2:
The variety was developed through controlled crossbreeding between 'Bountiful' and 'Paragon' to select for specific genetic parameters that enable high productivity in USDA zones 7b-9b. The breeding process optimized traits including heat tolerance, fruit set under stress, and yield consistency in the target climate zone.
4Shape
If raspberry varieties produce strong orange-yellow fruit, then fruit quality and color intensity increase, but fruit may be more susceptible to summer temperature damage
Solution Approach 1:
The patent describes a raspberry variety with documented fruit color parameters (RHS 17A) representing strong orange-yellow pigmentation. The breeding program selected for this specific color phenotype while simultaneously selecting for heat tolerance, achieving both high color intensity and summer temperature resilience in the same variety.

AI summary
This invention relates to a new and distinct everbearing variety of raspberry plant named ‘PS-12.082-54’. The new variety is primarily adapted to the growing conditions of the central coast of California and is characterized by the following: mid-season primocane production with medium sized fruit of strong yellow orange coloration. Fruit is of consistent conic shape, releases easily from receptacle, is very glossy and possesses an average % brix of 10.2. Foliage is flat, medium green; possessing weak rugosity, weak gloss and mostly 3 foliates. Primocanes have an absent or very weak waxy coat, medium prickle density of small green prickles and are absent of anthocyanin coloration.
