Genetic Purity

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.

Hybridity Test

Hybridity tests are used to determine parentage and purity of hybrid seeds. Hybrid seeds are produced by controlled pollination between parental varieties. Hybrids are often have improved vigor compared to their parents and are commonly favored in agriculture and gardening. Hybrids are not true-breeding, meaning the offspring of hybrid plants do not have the same characteristics as their hybrid parents. Therefore, hybrid seed must be purchased each growing season. Hybridity and varietal purity tests ensure that hybrid seeds are of good quality. For more information, see hybridity test.
