Analysis of physiological races of rice blast fungus in Zhejiang Province

doi:10.16178/j.issn.0528-9017.20230975

Abstract

Abstract:

This reseach uses 7 Chinese rice blast fungus physiological race identification varieties to identify and analyze 100 rice blast fungus strains in Zhejiang Province. It is found that the rice blast fungus strains in Zhejiang Province are mainly composed of 7 groups and 36 physiological races, with significant differences in the frequency of occurrence among each group. Among them, the frequency of ZA group strains is the highest, reaching 36.0%, indicating that ZA group strains have risen to become the dominant population in Zhejiang Province; Next are ZC and ZB strains, with frequencies of 24.0% and 22.0%, respectively. ZD, ZE, ZF, and ZG strains have lower frequencies of 4.0%, 8.0%, 2.0%, and 4.0%, respectively.

Key words: rice blast fungus, physiological races, Zhejiang

CLC Number:

S435.111
