A minimum percentage of fertile seeds is required in order to provide sufficient pollen in a mixed seed lot. Alternatively a sterile female can prevent the need for detasseling during hybrid corn production. Traditionally, the fertility/sterility percentage of a seed lot is determined via field grow out.
ICIA offers a molecular test to determine fertility/sterility percentage for S, C, and T cytoplasm types. This test is performed on 100 individual seeds and results are reported as % fertile.
