Identification of the Physiological Races of Rice Blast Fungus in Part Areas of Heilongjing Province in 2015
摘要
Abstract
Rice blast is one of the important disease in cold region. To identify the population structure and trends of rice physiologi-cal races in part areas of Heilongjiang Province, 7 differential hosts of China were used to analyze the physiological races collected from the counties of Heilongjiang Province in 2015. The results showed that 99 blast isolates were obtained and categorized into 6 groups with 17 races, and that ZA and ZD were the dominant groups, with the average frequency of 60.61% and 18.18%, respectively. The race ZA49 was the dominant race with the average frequency of 23.23%; secondly, the average frequency of the race ZD1 was 18.18%; moreover, the average frequency of the race ZA1 was 16.16%. The types and compositions of the physiological races were var-ied in different rice areas.关键词
