Hybrid Tomato Breeding for Ff, ToMV, and ToBRFV Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tomato varieties lack sufficient resistance to Cladosporium fulvum (Ff) groups A, B, C, D, and E, Tomato Mosaic Virus (ToMV) strains 0, 1, and 2, and Tomato Brown Rugose Fruit Virus (ToBRFV), as well as having uniform ripening and desirable fruit characteristics like medium plant height and very small oblong red firm fruit.
Innovation Solution
Development of a new hybrid tomato variety 72-MP0046 RZ with genetic traits providing resistance to Cladosporium fulvum (Ff) groups A, B, C, D, and E, resistance to Tomato Mosaic Virus (ToMV) strains 0, 1, and 2, and resistance to Tomato Brown Rugose Fruit Virus (ToBRFV), along with medium plant height and very small oblong red firm fruit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing tomato varieties are used, then cultivation is simpler, but resistance to Cladosporium fulvum, Tomato Mosaic Virus, and Tomato Brown Rugose Fruit Virus is insufficient
Solution Approach 1:
The patent combines multiple resistance traits (Ff groups A-E, ToMV strains 0-2, and ToBRFV) into a single hybrid tomato variety 72-MP0046 RZ, merging previously separate resistance characteristics that were developed in different parental lines to create a unified variety with broad-spectrum disease resistance
2Reliability
If tomato varieties with multiple disease resistances are developed, then pathogen protection is improved, but breeding complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific resistance traits before crossing, and by establishing standardized evaluation protocols for disease resistance assessment in the F1 generation, thereby streamlining the breeding process for developing multi-resistant varieties
