Types of samples

    1. Primary sample
    • Each probe or handful of sample taken either in bag or in bulk is called primary sample.
    2. Composite sample
    • All the primary samples drawn are combined together in suitable container to form a composite sample.
    3. Submitted sample
    • When the composite sample is properly reduced to the required size that to be submitted to the seed testing lab, it is called submitted sample.
    • Submitted sample of requisite weight or more is obtained by repeated halving or by abstracting and subsequently combining small random portions.
    4. Working sample
    • It is the reduced sample required weight obtained from the submitted sample on which the quantity tests are conducted in seed testing lab.
