Despite the recent advances made in the improvement of crucifer crops using conventional breeding techniques, the yield levels and the oil and meal quality could not be improved as expected. The understanding of genetic material (DNA/RNA) and its manipulation by scientists has provided the opportunity to improve crucifers by increasing its diversity beyond conventional genetic limitations. The application of the biotechnological techniques will have major impacts in two ways: first, it provides a number of techniques/methods for efficient selection for favorable variants and second, it gives...
