Double Gold Raspberry Plant Dual Fruiting and Tall Canes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Raspberry plants adapted to temperate climates like west central New York lack varieties that offer late fall primocane fruiting and early mid-season floricane production with very tall canes and distinctive golden to orange/red conical fruit, limiting harvest flexibility and cane growth.
Innovation Solution
The development of a new raspberry plant 'Double Gold' through a hand-pollinated cross of Cornell NY319 and 'Graton Gold', characterized by late fall primocane and early mid-season floricane fruiting, very tall canes, and golden to orange/red conical fruit, optimized for growth in protective structures like plastic hoop houses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If raspberry plants are grown in temperate climates without protective structures, then they can grow naturally, but the harvest season is limited and cane growth is restricted by frost risk
Solution Approach 1:
The patent applies preliminary action by selecting and breeding raspberry varieties with specific genetic traits (late fall primocane fruiting and early mid-season floricane production) before exposure to frost conditions. The protective structures are also prepared in advance to shield the plants during critical growth and harvest periods, allowing the full harvest season to be captured before frost damage occurs.
Solution Approach 2:
Protective structures such as plastic hoop houses and high tunnels serve as intermediary elements between the raspberry plants and the harmful frost environment. These structures create a microclimate that protects the canes and fruit from frost damage while allowing the plants to maintain their natural growth cycles and extended harvest window.
2Length of moving object
If raspberry varieties are selected for tall cane growth, then cane height and vigor are improved, but fruit size and weight may be reduced
Solution Approach 1:
The patent applies local quality by selecting for specific localized traits in different parts of the plant. The breeding program focuses on achieving tall, vigorous canes with extensive pigmentation in the stem tissue while simultaneously maintaining large fruit size and weight. This localized optimization allows the plant to allocate resources differently - investing in cane growth and pigmentation in certain areas while preserving fruit development in others.
Solution Approach 2:
The patent utilizes parameter changes by modifying genetic parameters through controlled breeding to achieve a new combination of traits. The breeding program changes the parameters of cane height, vigor, pigmentation intensity, and fruit weight simultaneously, creating a variety that exceeds the performance of parent varieties in multiple parameters rather than trading one off for another.
3Adaptability or versatility
If raspberry plants produce fruit on both primocanes and floricanes, then harvest flexibility is improved, but the complexity of managing different fruiting cycles increases
Solution Approach 1:
The patent applies periodic action by establishing distinct fruiting periods for primocanes (late fall from September to November) and floricanes (early mid-season from June to July). This periodic fruiting pattern allows growers to plan harvest operations around predictable time windows, reducing management complexity despite having dual fruiting cycles. The regularity of these periodic fruiting events makes the system more manageable than continuous or irregular fruiting would be.

AI summary
This invention relates to a new and distinct everbearing raspberry plant designated as ‘Double Gold’ primarily adapted to growing conditions of west central New York and other regions of similar climate. The new plant is primarily characterized by golden to orange/red conical fruit that is equally long and broad, vigorous tall canes, late season primocane production and early mid-season floricane production.
