The direct offspring of nucleus seed is designated__________________?
Show answer Hide answer
Answer: B. Breeder seed
Explanation
Breeder seed is the direct generation produced from nucleus seed under the supervision ofythe originating breeder. It maintains the highest level of genetic purity and serves as the source for all subsequent seed classes. Strict isolation and rigorous inspection protocols govern its production. Seed certification systems follow a structured hierarchy starting from nucleus and breeder seed down to certified seed. Breeder seed is produced in small quantities to preserve the exact characteristics developed during crop breeding. It is carefully managed by research institutions.
Quality seed multiplication is foundational to achieving high agricultural productivity and varietal uniformity. Commercial farmers ultimately plant certified seeds that trace their lineage back to original breeder stocks. Protecting breeder seed prevents genetic contamination early in the chain. Foundation seed, registered seed, and certified seed represent later downstream generations in the multiplication chain. They are derived from breeder seed rather than being its direct parent source. Therefore, breeder seed is the accurate term.
