Study on seed glucosinolate compositions differences between parents of Brassica juncea and Brassica napus and their progenies

The individual glucosinolate in the parents and progenies of interspecific crossing between Brassica juncea and Brassica napus was analyzed by HPLC, the results showed that the progenies that have similar agronomic character with parents have similar glucosinolate compositions with their parents, although the quantity of individual glucosinolate has changed indifferent level compared with the parents, it inclines to the maternal. There are more singrin and less progoitrin and gluconapin in Brassica juncea, whereas there are less sinigrin and more progoitrin and gluconapin in Brassica napus, so it^s possible to get the rapeseed with low content of above three kinds of glucosinolate through crossing and directional selection.
