Early Biomass Measurement for Mutant Cereal Yield Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the yield of mutant cereal crop lines are post-harvest based, resource-intensive, and of limited accuracy, often failing to predict yield performance until late development stages when significant resources have already been used.
Innovation Solution
A method involving the growth of mutant cereal crop lines, measurement of biomass within specific Zadok's growth stages (Z30 to Z39), and identification of lines with high biomass values for early selection and yield prediction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If post-harvest methods are used to determine yield, then yield data is obtained, but resource use and time input are high
Solution Approach 1:
The patent applies preliminary action by measuring biomass at growth stages Z30-Z39, which occurs before harvest. This early biomass measurement allows yield prediction to be made in advance, eliminating the need to wait until post-harvest assessment. The method performs the measurement action提前 (in advance) at specific growth stages, enabling early selection of high-yield mutant lines without completing the full growing cycle to harvest.
2Measurement precision
If post-harvest methods are used to determine yield, then yield data is obtained, but resource consumption is high
Solution Approach 1:
By performing biomass measurement at growth stages Z30-Z39 before harvest, the patent enables early identification of high-yield candidates. This preliminary assessment allows breeders to stop resource investment in low-yield lines early, avoiding the waste of continuing to grow and harvest large numbers of mutant lines that would ultimately prove to be poor performers.
Solution Approach 2:
The patent extracts the yield prediction function from the harvest process itself. Instead of requiring actual harvest and grain measurement, the method extracts yield information earlier through biomass measurement at Z30-Z39 stages, separating the yield assessment function from the terminal harvest event.
3Loss of time
If biomass measurement is performed at early growth stages, then resource use is reduced, but yield prediction accuracy may be insufficient
Solution Approach 1:
The patent applies parameter changes by specifying a particular growth stage window (Z30-Z39) for biomass measurement. This temporal parameter optimization ensures measurements are taken when plants have sufficient biomass accumulation to provide accurate yield prediction signals, while still being early enough to enable timely selection decisions. The method transforms the timing parameter of measurement to achieve both early assessment and adequate accuracy.
