KAY DIAMOND V Nectarine Tree Early Maturity and Fruit Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of nectarine tree that combines desirable traits such as early maturity, larger fruit size, and improved chilling hours, while maintaining firm texture and sweet flavor, which existing varieties like 'Rose Bright' do not fully address.
Innovation Solution
The 'KAY DIAMOND V' nectarine tree variety, developed through embryo rescue techniques and asexually reproduced using 'Nemaguard' rootstock, exhibits characteristics of being medium-sized, vigorous, self-fertile, and producing uniformly large, clingstone nectarines with a yellow flesh and full red skin, maturing five days earlier than 'Rose Bright' and requiring more chilling hours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If existing nectarine varieties like 'Rose Bright' are used, then firm texture and clingstone type are maintained, but fruit size is smaller and maturity is later
Solution Approach 1:
The patent applies parameter changes by selectively breeding nectarine trees to modify key parameters including fruit size (increased from smaller to uniformly large), maturity time (advanced by approximately one week), and chilling hour requirements (increased to 700 hours). These parameter changes resolve the contradiction by achieving both larger fruit size and earlier maturity while maintaining the desired firm texture and clingstone characteristics.
2Loss of time
If nectarine variety requires more chilling hours, then early maturity is achieved, but adaptability to different climates is reduced
Solution Approach 1:
The patent applies local quality by optimizing the nectarine variety for specific regional conditions (central California climate) while maintaining adaptability through controlled asexual reproduction. The variety is tailored to local chilling requirements (700 hours) to achieve early maturity in that specific region, while the use of standardized rootstock ('Nemaguard') and propagation methods ensures consistent performance across suitable climates.
3Stability of the object's composition
If asexually reproduced using 'Nemaguard' rootstock, then true-to-type reproduction is achieved, but rootstock compatibility limitations apply
Solution Approach 1:
The patent applies copying through asexual reproduction methods (budding and grafting) using 'Nemaguard' rootstock to create true-to-type copies of the selected nectarine variety. This ensures genetic fidelity and consistent fruit quality across all propagated trees, resolving the need for reproduction stability while acknowledging the limitation to compatible rootstock options.

AI summary
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica, broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in the early part of June, with first picking on Jun. 2, 2006. The fruit is uniformly large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm in texture, yellow in flesh color, and full red in skin color.
