摘　　要：绵油 12系采用阶梯式复合杂交,经多年优良基因重组逐渐积累,集型间、种间、地理及生态远缘之亲本的优良因子于一体的双低胞核两系杂交油菜新品种。它不但具有丰产性突出、增产潜力大、产量高的优点,而且芥酸、硫苷含量都达到国内自用标准,抗倒耐病力强,适应性广, 适宜在长江中上游的平丘区种植,也可以在其它类似生态区种植。Double-low GMS two-line hybrid cultivar Mianyou 12 was bred by multiple cross and stepped cross, which had accumulated excellent genes from distant parents deriving from interspecific and intervarietal hybridizations and different geographic ecotypes. It bears the characteristics of outstanding yield ability, low erucic acid and low glucosinolate content, strong ability of tolerance and resistance to diseases, resistance to lodging and wide adaption. It can be cultivated in hilly and plain area of Sichuan and other ecologies like that.
