Here researchers cross two parent lines whose desired properties complement each other as much as possible. From the offspring, homozygotic plant lines are developed, which are called line-bred varieties.
Line-bred varieties are very homogeneous and the offspring of the plants are genetically stable.
Time-consuming: Several cycles/generations must be cross-bred and bred through self-fertilization before the desired result is achieved.
Self-pollinated varieties in traditional agriculture, called landraces, consist of a variety of line mixtures. Line-bred varieties have, somewhat, developed from them.
