摘　　要：为解决香粳糯原品种种子混杂、退化和变异,造成品质变差、产量下降、商品性降低等问题,以融水县汪洞乡产儒村九龙屯沿习特有、名优的地方香粳糯原品种种子为材料,通过“三年三圃”提纯复壮技术和方法,以获得相对纯的、生活力强的、无混杂退化的香粳糯良种,使种子由杂转纯,由退化转化为复壮,提高其丰产性、适应性、抗逆性、稻米品质和种植者的经济效益,促进地方优势特色水稻品种资源保护、创新与开发利用。In order to solve the problems of supply and utilization of Fragrant glutinous japonica varieties and promote the protection, innovation and utilization of rice variety resources with local characteristics. Using Rongshui xiangjingnuo as breeding material, pure lines with typical and prominent comprehensive characters were selected as improved varieties through three nursery ststem comparison and selection method, and the effect of planting increased production was significant.It not only maintained the excellent characters of the original variety, but also improved the yield, adaptability, stress resistance and rice quality. It had played a good role in promoting industrial poverty alleviation.
