As the first major crops, corn breeding work has always been of great importance, and the previous work of the corn test species often there are some drawbacks, now use corn seed test instrument automated test species of maize, would undermine past exam Variety becomes a non-destructive test; it turns the artificial test into an automatic test, which makes the test from the sample to the head; the data that was accurate to the community level in the past is changed to the individual level of the plant, making the strain The analysis of inter-mutation becomes possible. Achieved major changes in corn test species!
So what kind of data can the corn test meter measure?
1. Corn grain analysis: Measurable grain number, grain length, grain width. The length and breadth of the seeds with indistinct embryo tips were not determined. The length and width of the seeds were calculated on the average of the length and breadth of seeds with embryonic tips. Can automatically filter out the seeds with indistinct embryo tip.
2. Analysis of corn spikes can automatically obtain ear length, ear thickness, baldness (adjustable for position adjustment), left and right panicles, edge angle, ear angle, and average grain height (thickness), including each grain tested. Width, grain color (R, G, B value of seed color), etc. The height (thickness) of each corn can be conveniently adjusted with the mouse wheel. With the A3 scanner, the average analysis value of 5 ears can be obtained automatically.
3. Corn cross-section analysis can automatically obtain the number of grain rows, ear thickness, axis thickness, and average grain length and average grain width parameters on the section. Among them, the number of grains = the number of grains in one circle of the cross section of the middle of the ear; the diameter of the ear = the diameter of the circumscribed circle of the ear; the diameter of the axis = the diameter of the axis circle; the grain length = (the diameter of the circumscribed circle of the ear - the diameter of the circle of the embryo tip) /2; grain width = (ears circumscribed circumference + embryo tip position line circumference)/2/number of grain rows.
4. Other analysis: 1000-grain weight, 100-grain weight, grain yield.
