- The mating or crossing of two plants or lines of dissimilar genotype is known as hybridization.
- In plants, crossing is done by placing pollen grains from one genotype, the male parent, on to the stigma of flowers of the other genotype, the female parent.
- The seeds as well as the progeny resulting from the hybridization are known as hybrid or F1.
- The progeny of F1, obtained by selfing or intermating of F1 plants, and the subsequent generations are termed as segregating generations.
- The term cross is often used to denote the products of hybridization, i.e. the F1 as well as the segregating generations.
