- W2355697989 abstract "China is one of the largest counties where epidemics of wheat stripe rust (Puccinia striiformis West. f. sp. triticiEriksson) causes a big problem in wheat production. The disease is a great threat in many wheat-growing areas, espe-cially when conditions are favorable to the disease epidemics. Studying the physiological specialization and monitoring dy-namics of races of P. striiformis West. f. sp. tritici Eriksson is important to understand the variation of the pathogen andits virulence, effectiveness of resistance genes in disease control, prediction of stripe rust epidemics, as well as diseasemanagement. Due to the variation of geographic and regional characteristics, diversity of population structures of thepathogen, and so forth, different countries use differential host differentials and nomenclature system of races of P. stri-iformis. China, United State of America and India have their own differential hosts and nomenclature systems of races re-spectively. In China, 32 races and more than 30 pathotypes were identified by using relatively stable Chinese differentialsduring 1957 - 2002, while in the US 80 races were identified by using US differentials until now. Another system of nomen-clature of races was put forwarded by Johnson in 1972. In this system both world and European differentials were includedas integrate differentials. This system is widely accepted and employed in Europe, Middle East, Asia, Africa, South Ameri-ca countries, Australia and New Zealand etc. In considering the variability in different countries and regions, additionaldifferentials were added into this system by various rust researchers around the world. In addition to the long-distance di-spersal of the pathogen spores and disease spread, the possible future developments in this area including differential compo-sition, method of race nomenclature, as well as the international communications among scientists in this research area arealso discussed." @default.
