美国科学家研究发现，把野生品种与商用水稻品种进行杂交后，能使产量提高10％－20％。研究人员说，这种水稻杂交的方法具有抗病毒的能力。纽约康奈尔大学的苏珊·麦库奇和她的同事在最近伦敦召开的自然生物工艺学组织会议上公布了这种技术及其他们的研究结果。麦库奇说，在成 American scientists found that the hybridization of wild varieties with commercial rice varieties can increase the yield by 10% -20%. The researchers said that this method of hybridization in rice has antiviral capacity. Susan McCukh of Cornell University in New York and her colleagues presented the technology and their findings at a recent meeting of the Nature Biotechnology Organization in London. McCuchs said that into
