Scope of Application: Applicable to rapeseed germplasm resource conservation and creation, genetic analysis, crop breeding, crop phenomics, and other related fields. Target Users: Universities, scientific research institutes, seed industry enterprises, and relevant enterprises engaged in smart agriculture and other related fields. Main Problems Addressed by Data Application: The 3D phenotype information of individual plants and crop populations analyzed via this database helps researchers in crop breeding, genetic analysis, crop science, cultivation management and other fields obtain high-quality phenotypic data, supporting precise breeding decision-making. The core algorithmic rules of this data analysis are designed to convert 3D point cloud data into genetic insights that can guide breeding, which mainly includes the following processes: 1. Intelligent Extraction of 3D Phenotypes: Based on point cloud segmentation and feature recognition algorithms (such as deep learning-based organ segmentation, geometric and morphological measurements), dozens of key agronomic trait parameters including plant height, branch angle, leaf area, silique quantity and spatial distribution, biomass estimation and more can be automatically extracted from 3D models of individual plants and crop populations. 2. Phenotype-Genotype Association Analysis: Combine the extracted high-dimensional phenotypic data with corresponding germplasm genomic data (such as SNP chip data), and use genome-wide association study (GWAS) statistical models to locate key genetic loci (QTL) that control important traits such as plant architecture and yield components. 3. Breeding Value Prediction and Screening Model: Based on historical phenotypic and genetic data, construct machine learning models (such as Random Forest, Support Vector Machine, etc.) to predict and rank the comprehensive performance of germplasm (such as ideal plant architecture, lodging resistance, potential yield), thereby realizing rapid screening of high-quality germplasm resources. In summary, through the analysis chain of "trait digital analysis → genetic locus localization → breeding value prediction", this workflow transforms 3D phenotypic data into targeted screening indicators and gene mining targets for variety improvement.
