Choosing Desirable Traits When Saving Seeds

TatSoi bolting

Those who save seeds are automatically considered plant breeders. A seed saver will choose desirable traits to pass along to future generations.

These would include taste, size, yield, disease resistance, etc. This act of selection is what makes one a breeder.

What is Plant Breeding From National Association of Plant Breeders

General Definition

Plant breeding uses principles from a variety of sciences to improve the genetic potential of plants. The process involves combining parental plants to obtain the next generation with the best characteristics. Breeders improve plants by selecting those with the greatest potential based on performance data, pedigree, and more sophisticated genetic information. Plants are improved for food, feed, fiber, fuel, shelter, landscaping, eco-systems services and a variety of other human activities.

Technical Definition

Plant breeding is the science-driven creative process of developing new plant varieties that goes by various names including cultivar development, crop improvement, and seed improvement. Breeding involves the creation of multi-generation genetically diverse populations on which human selection is practiced to create adapted plants with new combinations of specific desirable traits. The selection process is driven by biological assessment in relevant target environments and knowledge of genes and genomes. Progress is assessed based on gain under selection, which is a function of genetic variation, selection intensity, and time.
