| Resumo: |
Seed market is becoming global and globalization is growing very fast. To compete favourably in this new global seed world, quality and cost are and will be certanly the key issues. High seed quality can only be obtained by a thorough control of the entire seed production process, step by step from planning to final delivery. That requires science, technology, expertise, experience, good management and certanly, the most important, an absolute and unconditional commitment with quality. Seed testing for quality assurance is one important step in the process of production of high quality seed. In the late years a considerable amount of research has been published, particularly on the use of some Polymerase Chain Reaction DNA based new technologies (RAPD, microsatelites, AFLP) for genetic purity determinations in seed testing. As far as we know, no Brazilian seed company is using, on regular basis, RAPD or other molecular marker techniques in the determination of genetic purity in seed testing. Most of these are using morphological or physiological traits expressed by seed, seedling or mature plant and/or electrophoresis of seed or seedling proteins/isoenzymes for that purpose. Main reasons for that are: DNA molecular marker techniques are relatively new; lack of specialized personnel to run DNA molecular marker assays on routine basis; higher cost/sample when compared to proteins/isoenzymes electrophoresis.
