我国自1982年正式提出低芥高产育种以来,在各个育种部门的努力下,已先后推出了一批低芥酸新品系,在改善油菜品质方面迈出了一大步。由于种种原因,大多数新品系的产量都不够理想,难于直接推广于生产。 Since China formally proposed breeding of low-mustard and high-yield in 1982, a series of new strains of low-erucic acid have been launched under the efforts of various breeding departments. China has taken a big step forward in improving the quality of rape. Due to various reasons, the output of most new lines are not ideal enough to be directly promoted to production.
