摘　　要：2009年国家杂交水稻工程技术研究中心在老挝万象进行了杂交水稻试验示范,结果表明,在老挝短日高温条件下,供试杂交水稻组合生育期明显缩短,示范产量6.2~7.0 t/hm2,比当地常规对照品种（2.2 t/hm2）大幅增产。中国杂交水稻在老挝有广阔的发展前景。In 2009,the China National Hybrid Rice Research and Development Center conducted a hybrid rice experiment and demonstrative cultivation in Vientiane,Laos.The results showed that the Chinese hybrid rice varieties had a much shorter growth period under short daylength and high temperature conditions in Laos.Two hybrid rice varieties in the demonstrative production yielded 6.2 to 7.0 t/hm2 on average,much higher than the local check inbred rice variety（2.2 t/hm2）.It is indicated that Chinese hybrid rice will have a good prospect in Laos.
