Plant breeding and genetics is the science of improving plants for specific purposes. This can be done through traditional methods such as cross-breeding, or more modern methods such as genetic engineering. Plant breeding can be used to improve crops for better yield, disease resistance, or other desired traits. Plant genetics is the study of genes and their effects on plant growth and development. This knowledge can be used in plant breeding to create new and improved varieties of plants. It can also be used for things like predicting how a plant will respond to certain environmental conditions, or identifying genes that are associated with specific traits. Together, plant breeding and genetics is a powerful tool for improving the quality of our food supply.
