[0002] Corn is a widely planted food crop in the world. Its yield and quality are directly related to the benefits of agricultural production and food security. However, the traditional corn planting method often ignores the importance of breeding. The disadvantages of planting corn directly without breeding are obvious. Unselected seeds have complex genetic backgrounds and unstable traits, making it difficult to ensure consistent yield and quality. Corn planting without breeding often has difficulty coping with complex and changeable natural environments.
