Identity preservation helps maintain unique varieties to supply diverse markets with agricultural commodities. For more information, see identity preservation.
Genetic purity is a measure of seed quality based on contamination by other varieties and species. Genetic impurities occur when seed becomes contaminated with seeds of other species and when the seed itself has resulted from pollen contamination. For more information, see genetic purity.
Genotyping is the process of determining the genetic makeup of individuals. Genotype can refer to the genetic makeup of a single location in the genome, multiple locations in the genome, or the sequence of the entire genome. Genotyping has many uses in plant breeding, such as the ability to test seedlings for the presence of genes involved in disease resistance. Genotyping also allows breeders to quickly determine if a plant is true-breeding, or homozygous, for important genes. For more information, see genotyping.
In the United States, regulation of genetically engineered (GE) crops is done by the U.S. Department of Agriculture (USDA), the Food and Drug Administration (FDA), and the Environmental Protection Agency (EPA). Regulation is necessary to ensure that GE crops are safe for use and consumption, are not contaminating other crops, and are not harming the environment. For more information, see regulation of genetically engineered varieties.
