[0002] Corn seeds are reproductive bodies capable of growing into adult corn plants. They are formed by ovules through pollination and fertilization. Corn seeds are composed of three parts: seed coat, embryo and endosperm. Corn seeds are divided into four types: conventional seeds, inbred lines, single-cross seeds, double-cross seeds and triple-cross seeds. Before corn is planted, corn seeds need to be screened to ensure the quality of corn seeds, thereby increasing the survival efficiency and quality of corn. Currently, breeding screening is usually single-layer screening, which is not convenient for multi-level screening of corn seeds.
