Intelligent Seed Testing Analyzer: Key Technology for Precision Crop Breeding

In the fields of crop breeding, fine variety breeding, and yield prediction, traditional manual seed testing methods have low efficiency and significant errors, seriously restricting scientific research and production processes. The emergence of the test analyzer, which integrates advanced optical imaging and intelligent algorithms, is driving this key link towards the era of precision and intelligence.

Core principle: Intelligent image analysis

The core of the test analyzer lies in the precise collaboration between its "eyes" and "brain":

High definition imaging: Equipped with a 16 megapixel autofocus camera and a high brightness LED nano light guide backlight board (aluminum alloy frame), it ensures clear and shadow free seed contours, and significantly improves imaging fidelity through automatic distortion and uniformity correction.

Intelligent algorithm: Based on image processing techniques such as distance transformation, morphological operations, and convex hull detection, the software can accurately segment adhesive seeds and recognize boundaries. By using spatial transformation and positioning technology, key grain shape parameters such as area, perimeter, length, width, and aspect ratio of each seed are automatically calculated.

Data fusion: Combining the weight data of the balance input by the user, the system automatically calculates the thousand grain weight/hundred grain weight, achieving comprehensive analysis from morphology to weight.

Breakthrough technological advantages

1、Precision leap:

Counting error ≤ ± 0.2% (1-2000 particles/time), rarely requiring manual correction.

The measurement error of particle parameters (length, width, etc.) is ≤± 0.1mm.

The accuracy error of thousand particle weight analysis is ≤± 1mg.

2、Efficiency Doubling: With one click operation, a single analysis only takes seconds to minutes, which is tens of times more efficient than manual labor.

3、Comprehensive particle size analysis: Breakthrough in achieving precise measurement of adhesive seeds one by one, obtaining complete population particle size distribution data.

4、Intelligent workflow: The Android system provides simple and user-friendly operations, supports local data saving, Excel export, and seamless integration with cloud platforms (data uploading, retrieval by time period/category, multi-dimensional data display and bar chart analysis, online download/printing).

5、Professional adaptability: 0.5~20mm diameter seed particle compatibility analysis; For crops such as rice, it is necessary to separate the grains and grains by wind selection and count them separately to obtain accurate seed setting rates.

6、Continuous Evolution: Supports software online automatic updates, with built-in one click switching between Chinese and English.

Key application areas and solutions

Crop breeding: Quickly and accurately screen single plants or strains with excellent grain size and high thousand grain weight to accelerate the breeding process.

Seed quality testing: objectively evaluate the uniformity and plumpness of seed batches, providing core data support for graded pricing.

Field yield measurement and seed testing: Quickly count the number of grains per ear, analyze grain traits, predict and verify yield after harvest.

Research and teaching: Provide a large amount of accurate grain phenotype data to support genetic, physiological, and cultivation research.

Solution: Thoroughly solve the pain points of slow manual seed testing speed, large subjective errors, single data dimensions, difficulty in handling adhesive grains, and difficulty in managing historical data, and achieve full process digitization and traceability.

Industry pain point terminator: real case verification

Case 1: After the application of the seed analyzer by the Wheat Breeding Center of Shandong Academy of Agricultural Sciences, the daily processing of breeding materials increased by 5 times, and the standard deviation of thousand grain weight data was significantly reduced, effectively supporting the breeding of high-yield and high-quality new strains. Researchers have provided feedback: "In the past, manual counting work lasted for 3 hours, but now the instrument can accurately complete it within 3 minutes and synchronously obtain all particle size data, which is a revolutionary improvement in efficiency and data quality

Case 2: In the quality inspection of corn seeds, a large seed industry company in Hebei Province quickly completed the detection of grain uniformity and thousand grain weight of multiple batches of seeds through a seed analyzer, accurately eliminating unqualified batches, significantly reducing market risks, and enhancing brand reputation.

Case 3: The Rice Research Institute in the Yangtze River Basin utilizes its automatic counting and separate analysis of grain size and grain size (with the assistance of wind selection) to efficiently obtain a large amount of rice material setting rate data, providing key phenotypic support for stress tolerance research.
