The haploid breeding method of using anthers was successfully applied in the experiment of breeding new rice varieties, resulted in obtaining several dominant lines. From the second generation of the pollen plants, we made a series of cultivation test and observations for three years. We found that the main genetical characters and viguor between generations of the progenies were stable and even. The coefficient of variation (c. v) was below 5%, and could be maintained. Demonstration of cultiva- tion and productive assessment have confirmed its value and named it late ken type rice "Sin Sieu". This proves that after selection of partents and combination of crosses were made, anthers of the hybrid could be artifically cultured, through which pollen plants could be obtained. Among them , good lines could be selected. After testing their productive ability, followed by propagastion, new variety could be obtained. This is a fast and efficient approach in crop breeding.
