Occasionally we will find a variety that IEF does not adequately differentiate the inbred from the hybrid seed and we cannot effectively evaluate the percent hybridity. In these cases, Eurofins STA Hybrid Purity Services utilizes our highly specific molecular markers. MMT Hybrid Purity Testing differentiates DNA loci in your hybrid seed product but unlike IEF different DNA loci are visualized on a DNA Analyzer that converts the loci into digital images. MMT Hybrid Purity is also very rapid and digital images give a permanent record of the test results.
