所谓杂交水稻，是由两个具有不同遗传特性的水稻品种或类型， 一个作母本，一个作父本，经有性杂交以后而产生的一种新的杂合体。 这种杂种的第一代，在生产优势、适应性及经济性等方面胜过母本和 父本，这种现象称为杂交优势。具有两个遗传组成不同的亲本，做母本的去雄，等开花以后授以父本的花粉，母本上结得就是杂交种。

1.杂交水稻的亩产量超过普通水稻百分之十五至二十。
The yield of hybrid rice per mu exceeds that of ordinary rice by15 to20 percent.
2.袁隆平在上世纪70年代研发出全世界第一个杂交水稻品种，过去几年间，他研发的杂交水稻产量多次创造世界纪录，为中国和全世界的粮食安全作出了巨大贡献。
Yuan, who developed the world's first hybrid rice in the 1970s, has set multiple world records in hybrid rice yields in previous years, making great contributions to the food security of China and the world.
3.杂交水稻技术的进步，为解决我国粮食问题做出了重要贡献。中国现在用全球不到9%的耕地养活全世界约20%的人口。
China now feeds around 20 percent of the world's population with less than 9 percent of the world's arable land.
