scribed as hybrids. Hybrid seed production uses genetic recombination in a predictable way. Parent plants used to produce hybrids are from pure lines developed through inbreeding. Pure lines are plants that “breed true” or produce sexual offspring that closely resemble their parents. By crossing pure lines, a uniform population of a first filial generation hybrid seed can be produced with predictable characteristics. /
These first generation hybrids, in contrast to their true-breeding parents, are not true breeding. They can produce seed, referred to as second filial generation, with various genetic combinations for each trait.
Seeds produced by a first generation hybrid tend to develop into plants that are highly variable and generally inferior to their hybrid parents. These combinations can be observed when seeds are collected from a first generation hybrid and planted.
Know Which Plants
Can Be Self-pollinated
A few principles must be considered before attempting to breed plants. Some plants are tolerant of inbreeding and can be self-pollinated. These include houseplants such as asparagus ferns and spider plants, many perennials, and vegetable crops such as peppers and peas.
Other plant species exhibit inbreeding depression or self-incompatibility and must be cross-pollinated
