Principles of Quality Seed Production

Genetic, agronomic, and seed technology principles are key interventions for maintaining seed quality.
Production of genetically pure seed requires technical know-how, skill, and financial investment.
Varied interventions are needed based on flowering pattern, floral structure, pollination behavior, and genetic constitution of the variety.
Maintenance breeding is crucial for purifying and stabilizing released genotypes.
The initial seed for raising a certified seed crop should be from an approved source and of appropriate class.
Previous cropping history and isolation requirements are essential to avoid genetic contamination.
Isolation in time involves staggering the planting time of different varieties to prevent cross-pollination.
Isolation by distance is based on the concept that distant seed crops from cross-compatible crops will minimize pollen contamination.
Minimum varietal purity standards are specified for non-hybrids under OECD seed schemes.
For example, the minimum varietal purity standard for Triticum aestivum basic seed is 99.9% under OECD seed schemes.
The isolation distance recommended in regulations takes into account the method and mode of pollination.
The distance isolation is an efficient type to achieve in most crops and is based on the concept that if a seed crop is sufficiently distant from any other cross-compatible crop, the adverse pollen contamination will be negligible.
