油研10号大面积制种F_1代不育株率和异型株率控制技术

Techniques for Controlling Rates of F_(1) Sterile Plant and Unusual Plant of Youyan 10 in Seed Production

制种实践表明,隐性核不育杂交油菜油研10号大面积制种,F1代不育株率和异型株率完全可通过制种过程中净化制种环境、处理好可育株根桩、降低田间可育株残留比例和返工等措施进行有效控制,达到降低油研10号F1代不育株率和异型株率,保障新品种油研10号丰产性、稳产性,提高种植油研10号的经济效益。

The rates of F1 sterile plant and unusual plant of Youyan 10 in seed production can be reduced by purifying environment of seed production, cleaning rootstocks of fertile plants, decreasing the remain proportion of fertile plants and doing these work over again, which can ensure the yielding-stable ability of Youyan 10 and improve its economical benefits.
