1985年从20个省和自治区的70个市、县共采集标样385份,经繁殖成活152份,成活率为39.5％。生理小种21C3仍为当前优势小种,其次是34号小种。但是34号小种群的出现频率高出21号小种群。在190个菌株中各小种的出现频率是:21C2为0.5％、21C3为46.3％、34为21.6％,34C1为10.0％、34C2为7.9％、34C3为9.5％、34C4为2.1％、116为2.1％。寄主离体叶培秆锈菌小种鉴定方法和常规苗期鉴定结果,在109个菌株中符合程度是很理想的。
In 1985, a total of 385 standard samples were collected from 70 cities and counties in 20 provinces and autonomous regions. After breeding 152, the survival rate was 39.5%. Physiological race 21C3 is still the current dominant race, followed by 34 race. However, the emergence of 34th small population is higher than that of 21th small population. The frequency of occurrence of each race in 190 strains was 0.5% for 21C2, 46.3% for 21C3, 21.6% for 34, 10.0% for 34C1, 7.9% for 34C2, 9.5% for 34C3 and 2.1% for 34C4 and 116 for 2.1%. The results showed that it was very satisfactory in 109 strains to identify the method of identification of the invader ramets in vitro.
