Physiologic Race Identification of Rice Blast Fungus in Heilongjiang Province from 2007 to 2011
摘要
Abstract
In order to make clear composition and distribution of physiological races of the rice blast fungus in Heilongjiang ,299 mono-spore strains of the rice blast fungus (Pyricularia oryzae) were isolated from five rice growing regions(30 cities ,counties or farms)during 2007~2011 in Heilongjiang .7 groups with 31 physiological races were identified by comparing with seven China verified strains .The results showed that ZA ,ZD and ZB groups were the dominant groups in Heilongjiang province ,with the average frequencies of 34 .8% ,31 .1% and 16 .1% ,respectively .The race ZD5 was the dominant race with the average frequency of 17 .1% ,followed by ZA49 and ZD1 ,which average frequency was 13 .7% and 10 .7% ,respectively .The types and compositions of the races were different from place to place .关键词
