摘要
为了选育适宜中国种植的抗除草剂油菜品种,提高油菜田间化学锄草效率,降低油菜生产成本。以浓度为0.5%的EMS溶液对‘陕9B’进行诱变处理,创制具有抗除草剂特性的种质资源。经过大量筛选,获得了具有抗除草剂特性的油菜品系‘陕9BK’,利用其做轮回亲本,选育出具有抗除草剂特性的油菜细胞质雄性不育系‘陕9AK’;利用‘陕9AK’做母本配制杂交组合,其中组合‘陕9AK×R3’、‘陕9AK×R6’和‘陕9AK×R1’长势强,整齐一致,产量高,增产潜力大,抗病抗倒,苗期对除草剂的抗性强,适宜田间化学锄草。选育的‘陕9AK’细胞质雄性不育系有利于抗除草剂杂交组合的配制,在杂交种制种中可简化油菜制种程序,降低制种成本,提高农户种植效益。
The aims are to breed herbicide-resistant rapeseed varieties suitable for planting in China,improve the efficiency of field chemical weeding and reduce the cost of rapeseed production.’Shan 9 B’was treated with 0.5%EMS solution to create germplasm resources with herbicide resistance.By a large quantity of screening,a rape strain’Shan 9 BK’with herbicide resistance was obtained,and then it was used as the recurrent parent to breed rape cytoplasmic male sterile line’Shan 9 AK’with herbicide resistance;’Shan 9 AK’was used as female parent to make hybrid combinations,the combinations of’Shan 9 AK×R3’’Shan 9 AK×R6’and’Shan 9 AK×R1’had stronger growth vigor,uniformity,high yield,yield-increasing potential,disease resistance and lodging resistance.They also had strong resistance to herbicide at the seedling stage,and were suitable for chemical weeding in field.Cytoplasmic male sterile line’Shan 9 AK’is beneficial to breed herbicide-resistant hybrid combinations,which can simplify the seed production procedure of rapeseed in hybrid seed production,reduce seed production cost and improve farmers’planting efficiency.
