Correct option is C
The correct answer is: (C) Plant breeders
Explanation:
Nucleus seed is the first and purest form of seed in the seed production chain. It is produced and maintained by plant breeders to ensure genetic purity and is free from any impurities or off-types.
These seeds serve as the starting material for producing breeder seeds, which are then further multiplied into foundation and certified seeds.
Information Booster:
Seed production hierarchy:
Nucleus Seed → Produced by plant breeders, 100% genetically pure.
Breeder Seed → Derived from nucleus seed, maintains purity.
Foundation Seed → Produced from breeder seed, maintains genetic identity.
Certified Seed → Produced from foundation seed, used by farmers.
Characteristics of Nucleus Seed:
100% genetically pure.
Free from diseases and contaminants.
Used to produce breeder seeds.
