Need for Genetic purity assessmentEssential for quality seed production assessmentTo detect selfing in female plantsTo ensure that there are no mixturesTo settle disputesTo stake claims by the companyIt will be helpful in registrationAvoids grow-out test The traditional Grow out Test (GOT) is done to determine the seed genetic purity test based on morphological markers are time consuming and are environmental dependence. To overcome this, disadvantage the biochemical markers are being used in many crops. However, repeatability and accuracy of these results on biochemical markers are subject to question. This made a way for the use of DNA molecular markers particularly the co-dominant markers are of great importance for rapid assessment of hybrid and parental lines in genetic purity in major oilseed crops.
