Plant breeding incorporates traditional methods and modern scientific methods to modify and manipulate plant species to improve crops, food, fuel, plant-based products. The modification is done through processes like genetic engineering or controlled pollination to combine traits and produce the desired phenotypes and genotypes. The process ensures food security and increases the resistance and outcome for plants. It helps plants fight pests, advance crop growth, and sturdiness, and offer a better taste in some situations. The crossing can occur with closely related plants or distantly associated species depending on the traits wanted. Plant breeding has been going on for thousands of years and is practiced worldwide.
