Pathotype differentiation of Xanthomonas oryzae pv. oryzae and resistance evaluation of major rice cultivars in Fujian province
摘要
Abstract
To clarify the major pathotypes of Xanthomonas oryzae pv. oryzae(Xoo)and evaluate the resistance of major rice cultivars in Fujian province,five Chinese differential rice cultivars('Jingang 30''Tetep''Nanjing 15''Java 14'and'IR26')were used to identify Xoo pathotypes,and the resistance levels of major cultivated rice varieties in Fujian to bacterial leaf blight were further evaluated by artificial inoculation.A total of 116 of Xoo strains collected from Nanping,Zhangzhou,Quanzhou,Fuzhou,Sanming,Ningde,Longyan,and Putian in Fujian province were classified into eight pathotypes,namely pathotypes Ⅲ,Ⅳ,V,Ⅵ,Ⅶ,Ⅸ,New pathotype 4,and New pathotype 5.Among these,pathotype Ⅸ(65.52％),pathotype V(17.24％),and pathotype Ⅳ(12.93％)were the dominant groups.Among the 53 major rice cultivars tested,'Heliangyou 676''Ya-5you Mingzhan''Donglian No.5'and'Yuanfengyou 998'exhibited resistance to pathotype Ⅸ;'Heliangyou 676''Yongyou 1540''Ya-5you Mingzhan'and'Donglian No.5'showed resistance to pathotype V,and'Heliangyou 676''Yongyou 1540''Yongyou 9'and'Yexiangyou 676'demonstrated resistance to pathotype Ⅳ.Notably,'Heliangyou 676'exhibited resistance to all three dominant pathotypes(Ⅸ,V,and Ⅳ)of Xoo in Fujian.This study provides a theoretical basis for breeding disease-resistant rice cultivars and for the rational deployment of resistant varieties to control bacterial leaf blight.关键词
