Resumos

Com o objetivo de estabelecer um campo experimental para trabalhos de melhoramento genético do algodoeiro para resistência à murcha de Fusarium, uma gleba de aproximadamente 8.000m² foi plantada com cultivar suscetível e inoculada artificialmente, durante sete anos seguidos. Avaliada mediante sintomas externos e internos típicos, a incidência da doença, mesmo após as 14 inoculações, mostrou-se fraca e insatisfatória para os fins visados. Entre as possíveis causas do insucesso são discutidas as condições climáticas, a textura do solo, os métodos de inoculação, a eventual supressividade do solo para Fusarium e a ausência de interação fungo + nematóides.

In order to establish an experimental breeding field for Fusarium wilt resistance, in cotton, an area of about 8,000m² was artificially inoculated with the pathogen twice during the crop season. A total of 14 inoculations was performed along the 7 consecutive years of experimentation. However, taking into account the typical external and internal symptoms exhibited by the plants, the incidence of the diseases was considered low and unsatisfactory, as the final purposes are concerned. The possible causes of the unsuccess, such as climatic conditions, soil texture, method of inoculation, supressiveness of the soil to Fusarium and absence of Fusarium x nematodes interaction, are discussed.

The possible causes of the unsuccess, such as climatic conditions, soil texture, method of inoculation, supressiveness of the soil to Fusarium and absence of Fusarium x nematodes interaction, are discussed.
