1983～1984年,运用来自十个甘蔗主产县区自行分离纯化的甘蔗眼斑病菌12个菌株对省内11个主要甘蔗栽培品种进行苗期接种试验,结果表明,不同菌株在同一种的反应差异不大,但同一菌株在不同品种上的反应型差别明显,看来有生理分化问题,经初步鉴定,选3,闽糖70/611为高抗品种,可以在重病区推广。

From 1983 to 1984, 12 strains of R. solani isolated and purified by themselves from ten major sugar-producing counties were used to inoculate 11 major sugar cane cultivars in the province at seedling stage. The results showed that different strains reacted in the same kind The difference was not significant, but the reaction type of the same strain on different varieties was obviously different. It appeared that there was a physiological differentiation problem. After preliminary identification, selection 3 and Fujian sugar 70/611 were high resistant varieties and could be popularized in seriously ill patients.
