Mandarin Tree 11C017R Breeding for Low Seed and Non-Acidic Flavor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new mandarin tree varieties with improved characteristics, particularly those offering non-acidic flavor profiles suitable for fresh fruit consumption in markets with specific preferences, such as Asian markets.
Innovation Solution
A new mandarin tree variety '11C017R' was developed through breeding and mutation breeding techniques, combining the female parent 'Ellendale' and male parent 'Murcott', resulting in trees with low seed numbers, high fruit quality, and balanced sweetness, which are well-suited for Asian markets with non-acidic flavor profiles and suitable for long-distance shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional mandarin varieties are used, then they have high seed numbers, but this is undesirable for fresh fruit consumption markets
Solution Approach 1:
The invention extracts and eliminates the undesirable trait of high seed numbers from the mandarin fruit through selective breeding and mutation breeding, while preserving the desirable traits of fruit quality and production
Solution Approach 2:
The invention changes the genetic parameters of the mandarin variety through mutation breeding using cobalt 60 gamma cell, resulting in stable mutation that maintains high fruit quality and production while reducing seed numbers to 0-5 per fruit
2Ease of operation
If mandarin varieties with high acidity are used, then they have traditional flavor profiles, but they are unsuitable for Asian markets that prefer non-acidic fruit
Solution Approach 1:
The invention changes the chemical composition parameters of the fruit by achieving a balance between Brix levels (sweetness) and acidity, creating a non-acidic flavor profile that suits Asian market preferences while maintaining commercial viability
3Reliability
If mandarin varieties are selected for firmness, then they are suitable for long-distance shipping, but they may be difficult to peel
Solution Approach 1:
The invention optimizes the physical parameters of the fruit skin and flesh relationship, achieving a balance where the fruit remains firm for shipping but the peel separates cleanly from the flesh, making it easy to peel despite the firm texture
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The '11C017R' variety produces medium to large, firm, and easy-to-peel fruit with low acidity, meeting market preferences and demonstrating stability in production and shipping, while maintaining distinct mandarin characteristics.
Implementation Method 1
subject to two rounds of mutation breeding (2011, 1,385 plants; 2013, 387 plants) using a cobalt 60 gamma cell to create a stable mutation that maintained high fruit quality and production
