Responses of 15 Musa sp and 2 Heliconias sp cultivars to the inoculation of Ralstonia solanacearum E.F. Smith, causative agent of Moko

Abstract

The main objective was to establish the behavior of 15 cultivars of Musa sp and 2 cultivars of Heliconia sp against challenge insulation Moko (Ralstonia solanacearum) and specifically determine the type of R. solanacearum that occurs in the Littoral zone. (Biovar), and define levels of resistance/tolerance of cultivars Musa sp against Moko (Ralstonia solanacearum). To achieve the study of this disease was first detected in 1840 in British Guiana and appeared in epidemic form in Trinidad in 1895, today it is present in several producing countries banana America, where it causes big annual losses he set a completely randomized design (CRD), 15 treatments (cultivars of Musa and Heliconia) in three repetitions, each experimental unit was composed of 4 seedlings. The study results resistance/tolerance of the cultivars Musa sp against Moko (Ralstonia solanacearum) on plantain (AAB) banana and Heliconia sp (AAA) 17 varieties which the next plant matter (Harton, Curare, Limeño, are susceptible evaluated Barraganete, Guineo jardin and Gross Michel) reached this tage of death within 17 to 25 day sof differing varieties is more time to the presence of symptoms Maqueño purple, Maqueño green, Orito, Vinces and Heliconia.
