Hybrid plants are the specific result of plant breeders who engineer new varieties of plants deliberately by combining preferred or desirable characteristics of the parent plants. Hybridizing is a labor-intensive process that can be done in the field or in a laboratory and involves selecting specific plants, then removing the pollen-bearing anthers of the female plants so that only pollen from the selected male plants can be pollinated. Pollen is then manually transferred to the female plant. New plants must be cross-pollinated one generation at a time. These plants grow to full size, then develop seeds. Those seeds will not necessarily produce plants that look like the hybrid parents, but instead, might grow a unique attributed plant. Hybrid plants are not labeled.
