[目的]研究中国杂交水稻品种在柬埔寨马德望省的种植长势和产量表现,为中国杂交水稻在柬埔寨马德望省的推广应用提供参考.[方法]2012年旱季(1～4月),将3个中国杂交水稻品种(早优362、特优362和桂源优362)与当地水稻品种(Senpidao)种植于柬埔寨马德望省,测定比较不同品种农艺性状和产量.[结果]不同水稻品种株高间差异显著.中国杂交水稻品种株高均显著高于当地对照品种(Senpidao),但分蘖数较低.中国杂交水稻品种的每穗粒数和穗长也显著高于当地对照品种,其中特优362的每穗粒数最多,桂源优362的穗最长.早优362的千粒重均高于其他3个品种,而特优362和桂源优362的产量显著高于其他两个品种.此外,每穗粒数、穗长和产量间表现出极显著的相关性.[结论]中国杂交水稻适合在柬埔寨种植,旱季在马德望省的Toul Samrong土壤种植可比当地品种增产23％～38％.

[Objective]The aim of this experiment was to study the growth and yield of Chinese hybrid rice varieties planted in Battambang,Cambodia and to provide reference for their extension and application in Cambodia.[Method]The experiment was conducted in the dry season of 2012 (January-April). Three Chinese rice varieties viz.,Zaoyou362,Teyou362,Guiyuanyou362 and one local variety (Senpidao) were planted in Battambag,Cambodia to compare their agronomic traits and yield.[ Result ]There was significant difference in plant height among all rice varieties.Senpidao grew shorter than the other varieties,but its tiller number was higher than the hybrid rice varieties.Grains per panicle and panicle length of the hybrid rice were significantly higher than that of Senpidao and Teyou362 and Guiyuanyou362 showed the highest grains per panicle and panicle length,respectively.The 1000-grain weight of Zaoyou362 was higher than that of Teyou362,Guiyuanyou362 and Senpidao.The yields of Teyou362 and Guiyuanyou362 were significantly higher than both of Zaoyou362 and Senpidao.Furthermore,the grains per panicle and panicle length were significantly correlated with the yield of rice.[ Conclusion ]Three Chinese hybrid rice varieties were suitable for growing in Cambodia and their yields increased by 23-38％ as compared to Senpidao rice under Toul Samrong soil condition in dry season of Battambag,Cambodia.
