Hybrid Tomato 72-009 RZ Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tomato varieties face challenges in combining desirable traits such as high yield, disease resistance, and uniform ripening, while also being susceptible to conditions like drought and heat, which affects their performance and marketability.
Innovation Solution
Development of a new hybrid tomato variety, 72-009 RZ, which is bred to incorporate improved traits through a combination of genetic selection and breeding methods, including pedigree and recurrent selection, to achieve enhanced yield, disease resistance, and tolerance to environmental stresses, with specific characteristics summarized in Table 1.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional tomato varieties are used, then basic fruit production is maintained, but yield is limited and disease resistance is insufficient
Solution Approach 1:
The patent combines multiple desirable traits (high yield, disease resistance, uniform ripening) into a single hybrid variety by merging genetic material from selected parent lines. The hybrid tomato variety integrates resistance to multiple diseases (Tomato Mosaic Virus, Fusarium wilt, Verticillium wilt) with high yield potential, resolving the contradiction between productivity and reliability.
Solution Approach 2:
The patent utilizes controlled pollination and selective breeding to change genetic parameters of the tomato variety. By controlling the breeding process and selecting for specific traits, the variety achieves improved yield and disease resistance simultaneously, transforming the genetic composition to resolve the technical contradiction.
2Productivity
If tomato varieties are bred for higher yield, then productivity increases, but uniformity of ripening and plant characteristics deteriorates
Solution Approach 1:
The patent applies local quality by ensuring uniform ripening characteristics are maintained in specific regions of the plant while allowing for variety-level yield improvement. The hybrid variety exhibits synchronous ripening of fruits, which is a localized uniformity property that coexists with high overall yield, resolving the contradiction between productivity and compositional stability.
3Adaptability or versatility
If conventional varieties are used, then basic growth is maintained, but tolerance to environmental stresses like drought and heat is insufficient
Solution Approach 1:
The patent incorporates stress tolerance traits through preliminary selection and breeding of parent lines that exhibit resistance to drought and heat. The hybrid variety is pre-equipped with these adaptive characteristics, enabling it to perform reliably under environmental stresses before they are encountered during commercial production.
