长期以来,生产上栽培的油菜新品种多为高芥酸(芥酸含量高达40％～50％)品种,营养价值较低。故“六五”以来,低芥酸油菜新品种的选育研究,一直被列为国家重点科技攻关项目。经过二十余年的努力,我国已先后育成了43个单、双低新品种。但是,早期育成的一批优质油菜品种,由于丰产性、抗逆性等不如当时的推广品种,加之优质没能优价,生产上实际应用的较少。绵油9号系四川省绵阳市农科所育成,1998年通过四川省审定的油菜新品种,该品种集高产、优质、高油、低芥酸、抗逆性强等优点于一体,在生产上已初步展示出十分广阔的推广应用前景。
For a long time, the production of new rape cultivated in the production of high-erucic acid (erucic acid content as high as 40% to 50%) varieties, lower nutritional value. Therefore, since the Sixth Five-Year Plan, the breeding of new low erucic acid rape varieties has been listed as a national key scientific and technological project. After more than 20 years of efforts, China has bred 43 single and double low-grade varieties. However, a number of high-quality rapeseed cultivars bred early, due to high yield, resistance and so less than the promotion of varieties at that time, combined with the high quality did not price, production less practical application. Mianyang 9 was bred by Mianyang Academy of Agricultural Sciences in Sichuan Province. In 1998, it passed the new rapeseed variety approved by Sichuan Province. It combines high yield, high quality, high oil, low erucic acid and strong resistance in one production. Has initially demonstrated a very broad promotion and application prospects.
