Seed of food crops including edible oil seeds and seeds of fruits & vegetables.Cotton seedsSeeds of cattle fodderJute seedsSeedlings, tubers, bulbs, rhizomes, roots, cuttings, all types of grafts and other vegetatively propagated material for food crops (or) cattle fodder
Importance of quality seed
Ensures genetic and physical purity of the cropsGives desired plant populationCapacity to withstand the adverse conditionsSeedlings produced will be more vigourous, fast growing and can resist pest and disease incidence to certain extentEnsures uniform growth and maturityDevelopment of root system will be more efficient that aids absorption of nutrients efficiently and result in higher yield.It will respond well to added fertilizer and other inputs.Good quality seeds of improved varieties ensures higher yield atleast 10 – 12 %
Major seed quality characters
Seed quality is the possession of seed with required genetic and physical purity that is accompanied with physiological soundness and health status. The major seed quality characters are summarized as below.
Physical Quality: It is the cleanliness of seed from other seeds, debris, inert matter, diseased seed and insect damaged seed. The seed with physical quality should have uniform size, weight, and colour and should be free from stones, debris, and dust, leafs, twigs, stems, flowers, fruit well without other crop seeds and inert material. It also should be devoid of shriveled, diseased mottled, moulded, discoloured, damaged and empty seeds. The seed should be easily identifiable as a species of specific category of specific species. Lack of this quality character will indirectly influence the field establishment and planting value of seed. This quality character could be obtained with seed lots by proper cleaning and grading of seed (processing) after collection and before sowing / storage.Genetic purity: It is the true to type nature of the seed. i.e., the seedling / plant / tree from the seed should resemble its mother in all aspects. This quality character is important for achieving the desired goal of raising the crop either yield or for resistance or for desired quality factors.
