运用减压渗透法将玉米、小麦、小米、高粱、狼尾草的DNA导入水稻品种紫稻，可产生多种多样的变异类型．性状变异包括：生育期、株型、穗型、粒形、花粉育性等．有的是供体特有性状，有的是新性状。从变异后代中，获得了一批性状优良并能稳定遗传的材料．减压渗透法操作简单，转化率高，为谷类作物导入外源DNA提供了一条新途径．
Introducing DNA from corn, wheat, millet, sorghum, and Pennisetum into rice varieties of purple rice using pressure-reducing infiltration can produce a wide variety of variation types. Variation traits include: growth period, plant type, panicle type, grain shape, pollen fertility and so on. Some are donor-specific traits, some are new traits. From the mutant offspring, a number of excellent and stable genetic material was obtained. Decompression infiltration method is simple, high conversion rate, the import of foreign DNA for cereal crops provides a new way.
