芥菜型和甘蓝型油菜及其杂种后代种子硫甙组成差异的研究

用高效液相色谱技术分析了芥菜型油菜（Ｂｒａｓｓｉｃａ ｊｕｎｃｅａ）和甘蓝型油菜（Ｂｒａｓｓｉｃａ ｎａｐｕｓ）种间杂种后代及共亲本的硫甙组成。结果表明，与亲本农艺性状相似的后代，那么其硫甙组成与亲本亦相似。各后代中硫甙组成与亲本相比，虽发生了不同管理的变化，但都有倾向母体的趋势。芥菜型油菜烯丙基硫甙含量，２－羟基－３－丁烯基硫甙含量低，而甘蓝型油菜２－羟基３－丁烯基硫甙含量高，烯丙基硫甙含量最低

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 crossingbetween Brassica juncea and Brassica napus was analyzed by HPLC,the results showed that the progenies that have similar agronomic character with parents have similar glu-coslnolate compositions with their parents,although the quantity of individual glucosino-late 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,soit's possible to get the rapeseed with low content of above three kinds of glucosinolatethrough crossing and directional selection. Our initial practice has proven that interspe-cific crossing,especially Brassica juncea crossing Brassica napus is a new way to createlow glucosinolate germplasm.
