PATINO-PACHECO, Mónica Jovanna  e  PEREZ-CARDONA, Olga Yanet. Evaluation of the resistance of Passifloras genotypes to Fusarium solani f.sp. passiflorae in granadilla. Entramado [online]. 2021, vol.17, n.2, pp.256-267.  Epub 29-Jan-2022. ISSN 1900-3803.  https://doi.org/10.18041/1900-3803/entramado.2.682.

In Colombia the most limiting disease in the cultivation of granadilla is neck rot caused by Fusarium solani f.sp, passiflorae. This pathogen affects plants in all stages of development at the base of the stems and causes death in a short time. The objective of this research was to evaluate the resistance in eighteen species of the Passifloraceae family to neck rot. For this experiment, a highly virulent isolate was used according to the results of pathogenicity tests with passion fruit plants. According to the results after inoculation with the pathogen, eleven Passifloras species were susceptible, in contrast, five passion fruit genotypes (PE10, PE11, PE13, PE15 and PE17) and two cholupas (PM02 and PM04), were resistant and did not show symptoms. It is recommended to use resistant species for the genetic improvement of this species or to use them as rootstock.
