Mutant Cullin1 Gene for Compact Watermelon Cultivation Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watermelon plants require large amounts of space for growth and fruit development, leading to inefficient cultivation and reduced fruit production when planted in dense populations.
Innovation Solution
Introduction of a mutant Cullin1 gene in watermelon plants, which confers a compact growth phenotype characterized by shorter internodes and smaller leaf areas, allowing for higher planting densities and reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If watermelon plants are planted with wide spacing (0.6-1.2m within rows, 1.8-2.4m between rows), then each plant has sufficient space for growth and fruit development, but the field size required is large and cultivation efficiency is low
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters of the watermelon plant through mutation breeding. Specifically, mutants with altered growth habits (compact growth phenotype) are selected, which change the plant's spatial requirements. This allows the same plant to occupy less space while maintaining fruit production capability, thereby resolving the contradiction between field size and cultivation efficiency
2Productivity
If watermelon plants are planted in higher densities to reduce space requirements, then cultivation efficiency improves and field size is reduced, but the number of fruits per plant decreases
Solution Approach 1:
The patent uses parameter changes by selecting mutants with modified growth parameters. The compact growth phenotype changes the plant's resource allocation pattern, allowing higher planting densities without proportionally reducing fruits per plant. This genetic parameter change enables the system to achieve both higher density and maintained fruit production
3Quantity of substance
If watermelon plants with standard growth phenotype are cultivated, then sufficient fruits per plant are produced, but the space required for cultivation is large and pruning work is extensive
Solution Approach 1:
The patent applies parameter changes by selecting mutants with compact growth habit. This genetic modification changes the plant's architectural parameters (internode length, branching pattern), which naturally reduces the need for pruning operations while maintaining fruit production. The ease of operation improves because the compact phenotype requires less intervention

AI summary
The present invention relates to a mutant Cullin1 gene which when present in a watermelon (Citrullus lanatus) plant leads to a compact growth phenotype that enables efficient cultivation. The invention also relates to watermelon plants comprising the mutant Cullin1 gene. The mutant Cullin1 gene provides watermelon plants with a compact growth phenotype, i.e. comprising shorter internode length and/or a smaller leaf area when compared to watermelon plants not comprising the mutant Cullin1 gene. The invention further relates to the use of the mutant Cullin1 gene for the identification and development of a plant showing a compact growth phenotype.
