Oilseeds are grown in order to extract oil from their seeds; But they are also considered as a valuable source of protein, and the residue of the product after de-oiling is used for this purpose. Both oil and flour are equally important and need special analysis, which is important in the purity of cultivar seeds. A very small impurity with other genetic materials may severely reduce the quality of the obtained oil or the flour produced from them may contain toxic substances; Therefore, seed breeders should be especially careful to avoid mating or contamination of inappropriate pollen sources.
