Open pollination is pollination by insects, birds, wind, or other natural mechanisms, and contrasts with cleistogamy, closed pollination, which is one of the many types of self pollination.[1] Open pollination also contrasts with controlled pollination, which is controlled so that all seeds of a crop are descended from parents with known traits, and are therefore more likely to have the desired traits.
