摘要
华双1号是我校育成的第1个甘兰型双低油菜品种.含油量43%,油中芥酸含量低于1%,每克菜饼中的硫苷含量低于35μmol,饼中蛋白质含量高于40％,适于三热或两热地区种植.文中对油菜品质育种策略进行了讨论.认为在品质育种过程中,对综合优良经济性状,特别是单株有效角果数的选择,以及开展回交,复交和轮回选择,是今后值得重视的问题。
Hua-double NO. 1 is the first double low cultivar of B. napus L bred in H.A.U.. The oil content of the cultivar is 43%.Its erucic acid content in oil is lower than 1% and its glucosinolates content is lower than 35nmol/g. Its protein content in meal is higher than 40%. These characters fully meet the requierements of high quality rapeseed production. Its early maturing character enable the cultivar to be grow on double or triple cropping regions. The tactic for quality improvement breeding was discussed. Four inexpedient approaches practiced in ordinary breeding had to be improved. Appropriate considerations would be given to the selection of multiple agronomic traits, especially the numbers of siliquae per plant, as well as the methods of backcrossing, multiple crossing and recurrent selection.
