Question

properties of good quality seeds

Answer 1

Characteristics of good quality seed

Higher genetically purity:

Higher physical purity for certification.

Possession of good shape, size, colour, etc., according to specifications of variety.

Higher physical soundness and weight.

Higher germination ( 90 to 35 % depending on the crop)

Higher physiological vigour and stamina.

Answer 2

The use of good quality seed is a prerequisite for the satisfactory production of a good quality crop and is essential for export markets. The following points should be taken into account when considering seed quality:

Trueness to type (often referred to as variety purity).

Satisfactory germination and vigour.

Freedom from other materials, including plant debris, dead or broken seeds, seeds of other crops, weed seeds, noxious and parasitic weed seeds also non-plant materials.

Freedom from seed-borne pests and diseases.

Good quality seed is essential for the production of a crop suitable for export. Although some farmers produce their own seed, only that seed which has been produced by a Seed Certification Scheme or the Quality Declared Seed system (QDS) should be used. The QDS system has been designed by FAO to ensure that the best possible quality seed is produced with the resources already available in seed production organizations in a country. The system is designed to provide quality control during seed production which is less demanding on government resources than fully developed seed certification, but adequate to provide good quality seed both within countries and in international trade. Full details of the Quality Declared Seed scheme are published by FAO

Trueness to type (often referred to as variety purity). Satisfactory germination and vigour. Freedom from other materials, including plant debris, dead or broken seeds, seeds of other crops, weed seeds, noxious and parasitic weed seeds also non-plant materials. Freedom from seed-borne pests and diseases.
