Breeding in self-pollination crops can be regarded as inbreeding. Self-pollination is a type of reproduction in which the pollen from the male part of a flower fertilizes the female part of the same flower or another flower on the same plant. In self-pollination crops, such as wheat, rice, and soybeans, the flowers are typically self-fertile, meaning they contain both male and female reproductive organs, and can fertilize themselves without the need for pollen from other plants. Inbreeding is the process of mating closely related individuals, such as siblings or cousins, within a population. In self-pollination crops, inbreeding can lead to the development of homozygous lines, which have two identical alleles for a particular gene. Homozygous lines are desirable in plant breeding because they produce offspring that are genetically uniform and can be reliably propagated. Line breeding, cross-breeding, hybridization, and back-crossing are other breeding methods that can be used in plant breeding, but they involve the use of different breeding techniques and may not be suitable for self-pollination crops.
