Morphological characterization of tomato accessions (Solanumspp.) in the Vinces river basin - Ecuador

Abstract

Tomato is affected by pests and diseases that are controlled with application of agrochemicals
that affect human health. Resistant genes obtained from wild Solanum should be used in order
to avoid this. In Ecuador, there is little research on this subject and the country is lacking of a
germplasm bank that guarantees adequate conservation of the genetic material. The goalsof
this study were: To inventory Solanum spp. inthe Vinces River basin and to characterize them
morphologically. The methodology was to collect the wild material, from which 10 accessions
were chosen, whose seeds were planted and cultivated. A complete randomized block design
was used. The Bioversity International descriptors were used in the morphological characterization.
This assayallowed to perform the morphological characterization of the accessions of
Solanumspp in this area.
