HND-32 Pineapple Hybrid with Ochre Shell and Ivory Pulp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a continued need for pineapple varieties with distinct pulp color and unique, enjoyable fruit flavor, as well as tolerance to natural flowering differentiation, which existing varieties do not adequately address.
Innovation Solution
The development of the new pineapple variety 'HND-32', which inherits compact plant architecture, ochre shell color, whitish pulp, and tolerance to natural flowering differentiation from its parents, combining desirable traits such as spiny leaves, long conical crown, and a consistent sweet-acid flavor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing pineapple varieties are used, then common fruit characteristics are maintained, but distinct pulp color and unique flavor are not achieved
Solution Approach 1:
The patent applies parameter changes by developing a pineapple variety with specific genetic traits that produce distinct physical and chemical parameters: ochre shell color, whitish pulp color, and a unique sweet-acid flavor profile. This resolves the contradiction by changing the fundamental parameters of fruit appearance and taste to achieve both distinctiveness and market appeal.
2Adaptability or versatility
If natural flowering differentiation occurs, then genetic diversity is increased, but breeding precision is reduced
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental varieties with desired traits (Dole-12 with ochre color and NDF tolerance, Dole-11 with sweet-acid flavor) before crossing. This preliminary selection ensures that the hybrid offspring inherit specific desirable characteristics, maintaining breeding precision while allowing natural flowering to occur.
Solution Approach 2:
The patent applies feedback by evaluating the hybrid offspring for specific traits (ochre shell color, whitish pulp, sweet-acid flavor, and NDF tolerance) and selecting only those that meet the desired standards. This feedback mechanism ensures that genetic diversity from natural flowering does not compromise the precision of achieving target characteristics.
3Reliability
If hybridization is performed to combine traits, then fruit quality is improved, but breeding complexity increases
Solution Approach 1:
The patent applies merging by combining the desirable traits of two parental varieties (Dole-12's ochre color and NDF tolerance with Dole-11's sweet-acid flavor) into a single hybrid variety. This merging achieves improved fruit quality consistency by integrating multiple beneficial characteristics into one stable genotype, while the controlled breeding process manages the complexity.

AI summary
A new pineapple (Ananas comosus) variety of the Bromeliaceae family was developed from a cross between the parental genotype ‘Dole-12’ and the commercial variety ‘Dole-11’ and has been designated ‘HND-32’. This new variety combines from its progenitors' different characteristics producing a unique hybrid showing irregular presence of spines in leaf margins, green leaves with red mottling colors, a reddish inflorescence at bottom stage, a cylindrical-slight taper shaped fruit with a long-conical crown, a distinctive ochre shell color, and an ivory white pulp with balanced sweet/acid-pleasant flavor, and tolerance to natural flowering differentiation.
