试验用链霉素等１０种抗生素对甘蓝型油菜品种陇油２号和白菜型油菜品种陇油３号的种子进行浸泡处理，以诱发突变。结果得到５２株雄性不育株，其中从陇油２号中得到１３株，从陇油３号中得到３９株。现蕾期链霉素注射处理，只从陇油３号中得到３株不育株，在陇油２号中没有找到不育株。苗期喷施链霉素处理，只从陇油２号中得到４株不育株，而在陇油３号却没有发现不育株。 Ten antibiotics, such as streptomycin, were used to soak seeds of Brassica napus Longyou 2 and Brassica campestris longyou 3 to induce mutation. As a result, 52 male sterile plants were obtained, of which 13 were obtained from Longyou 2 and 39 from Longyou 3. In budding streptomycin injection, only three sterile plants were obtained from Longyou No.3, and no sterile plants were found in Longyou No.2. Spraying streptomycin treatment at seedling stage, only 4 plants were obtained from Longyou No.2, but no plants were found in Longyou No.3.
