Abstract:

【Objective】 The pathogenicity of 6 populations of Radopholus similis from ornamental introduced into China were tested to seedlings of four banana cultivars. 【Method】 Pot inoculation was used in greenhouse tests. 【Result】 The six populations of R. similis tested obviously infected the roots of Musa paraolisiaca, Musa ABB Pisang Awak and Musa acuminata cv. Mas and reduced their plant growth. However only two populations of R. similis were weakly infected the roots of Musa AAA Giant Cavendish cv. Baxi. 【Conclusion】 The results demonstrated the significantly differences in pathogenicity of 6 populations of R. similis from ornamantals to seedlings of different Musa spp. The pathogenicity of 6 populations of R. similis was significantly different to the same variety of bananas, and different varieties of bananas showed different susceptibility to the same population of R. similis.

Key words: Radopholus similis, populations from ornamentals, Musa, pathogenicity
