Question

write a lab activity for selection of good quality of 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.

Farmers always select good seeds before sowing. Small or broken seeds contain less nutrients which are not sufficient for the developing seeds. Thus these inferior seeds are removed before sowing. Then these selected seeds are treated with hot water or chemicals to make them disease and pest free.
