对杂交油菜种子进行科学的质量分级,是当前种子生产和质量管理方面急待解决的问题。通过试验研究认为,对于育成时间短,应用面积小的杂交组合进行种子质量分级,条件尚不成熟。但对推广时间长。面积大、质量比较稳定的质不育“三系”和核不育“两系”杂交组合制定种子质量标准则是可行的。该文依据试验结果,探讨了质不育“三系”和核不育“两系”油菜杂交种种子质量的分级问题。
Scientific grading of hybrid rape seeds is an urgent issue in seed production and quality control. According to the experimental study, the seed quality grading for hybridization combinations with short incubation time and small application area is not yet mature. But for a long time to promote. Large area, relatively stable quality of sterile “three lines” and nuclear sterile “two lines” hybrid combinations to develop seed quality standards are feasible. Based on the experimental results, the paper discussed the grading of the seed quality of the “three lines” of CMS and the “two lines” rape hybrid seeds.
