Crop improvement refers to the scientific methods used to enhance the quality and yield of agricultural crops. This can involve traditional techniques like selective breeding, where farmers choose plants with desirable traits to reproduce, as well as modern methods such as genetic engineering. The goal is to develop crops that are more resilient to pests, diseases, and environmental conditions. Another important aspect of crop improvement is the use of advanced technologies, such as biotechnology and genomics. These tools help researchers understand the genetic makeup of plants, allowing for more precise modifications. Ultimately, crop improvement aims to ensure food security and sustainability in agriculture.
