摘　　要：在核不育两系杂交油菜制种中,把握种子质量是种子生产的核心,提高制种单产是增加制种户积极性和主动性的重要保证,同时也是生产高质量种子的重要条件。贵州省农科院油料研究所自2000年开始在遵义县制种以来,紧紧围绕种子质量开展工作,以提高农户制种产量为出发点,因地制宜,不断完善制种技术和基地组织管理,使黔油14号制种获得了大面积平均单产785.52 kg/hm2以上、不育株率控制在5%以下的制种效果。Seed quality is core of seed production of hybrid with recessive genie male sterile in B. napus. It is important to increase seed yield for raising seed producer＇s initiative which is the significant factor turning out high quality seed. Increasing seed quality and seed yield is our working aim in production of hybrid. Through improving technique of seed production and administration, the seed yield of Qianyou 14 reached 55 kg/667m^2 in average in large area and the male sterile plant rate is 5% below.
