The highest category of seeds produced under the direct responsibility of the breeder to maintain the genetic purity and identity of the variety.

Pre-basic seeds are the foundation of any seed multiplication chain. They are used by specialized seed companies to produce subsequent generations of certified seed, ensuring that the final crop meets the standards for purity and performance.
Farmers rely on these seeds to perform variety renewal, which helps to mitigate the effects of natural genetic drift. Common mistakes include planting pre-basic seeds directly for large-scale commercial production, which drastically increases operational costs without proportional profit gains.
