本试验将玉米ＤＮＡ直接导入水稻的种胚内，经过培育，子代的遗传性状发生了明显的变异，选育出具有株高降低、生育期缩短、穗长粒多、结实率高、米质变优等特点的水稻新品系。表明植物分子育种方法可使受体植物的遗传性状发生变异，是一种简便快速的育种新途径 In this experiment, DNA of maize was directly introduced into the embryo of rice, and after the cultivation, the genetic characters of offspring had obvious variation. Breeding had the characters of lower plant height, shorter growth period, longer ear length, higher seed setting rate, Excellent characteristics of new rice lines. It shows that plant molecular breeding method can make the variation of genetic traits of recipient plants, which is a new and easy way of breeding
