水稻细菌性条斑病(Xanthomonas0ryzicola Fang et al,下称细条病)在我县始见于1987年,从1990年开始上升为杂交水稻的主要病害。轻病田块损失5%～20%,重病田块损失30%～40%,且随着高感品种种植面积的进一步扩大,病害发生有不断加重趋势。为了遏制病害的流行趋势,我们对水稻品种抗病性进行调查研究,现将结果报道如 Rice bacterial leaf streak (Xanthomonas odorige Fang et al, hereinafter referred to as thin strip disease) in our county began to appear in 1987, from 1990 onwards rose to the main disease of hybrid rice. Light loss of field blocks 5% to 20%, severe disease 30% to 40% loss, and with the further expansion of high susceptible cultivated area, the occurrence of diseases continue to increase. In order to curb the epidemic trend of disease, we investigated the disease resistance of rice varieties, the results reported
