杂交水稻于1973年首先在我国育成,其后大面积种植,对我国水稻增产和米质的改良起了巨大的促进作用。但在大面积推广中,常发生水稻杂交种与三系种子搞错和販卖假杂交种情况,造成了严重的经济损失,影响了杂交水稻的声誉。为解决杂交水稻及其三系种子鉴定问题,许多种子工作者,从1976年开始进行了多方面的研究,已取得很大的进展。其中有的方法已被应用,效果良好。 Hybrid rice was first bred in our country in 1973 and then planted in large area, which greatly promoted the rice yield and rice quality in our country. However, during large-scale popularization, the occurrence of false hybrids and the sale of counterfeit hybrids between rice hybrids and three-line seeds often cause serious economic losses and affect the reputation of hybrid rice. In order to solve the problem of identification of hybrid rice and its three-line seeds, many seed workers have made various studies since 1976, and great progress has been made. Some of these methods have been applied and worked well.
