Abstract

ABSTRACT The tomato cultivation in the Amazon is not feasible mainly due to the natural infestation of Ralstonia solanacearum in the soil. Preventive control through grafting has been one of the main alternatives to manage this problem. This study aimed to evaluate the compatibility of Solanaceae genotypes as rootstocks for 'Santa Clara' tomato, aiming to control the bacterial wilt. Five rootstocks were evaluated: cubiu; red jurubeba; jurubebão; commercial hybrid tomato rootstock Guardião; and 'Santa Clara' tomato (self-grafting). In the seedling phase, characteristics of rootstock survival rate and compatibility were evaluated; while, in the field, that happened for survival rate, compatibility and fruit yield. In the seedling phase, Guardião and red jurubeba showed the best performances. In the field, red jurubeba presented a low compatibility, although it obtained the best productive performance among the wild rootstocks. Guardião obtained the best compatibility and yield among the studied rootstocks. Grafting is a viable technique for tomato production under soil-borne disease conditions.

Tomato (Solanum lycopersicum L.) belongs to the Solanaceae family and comes from Andean regions inhabited by the Incas in Peru, Bolivia and Ecuador (Filgueira 2007)

Summary

Introduction

Tomato (Solanum lycopersicum L.) belongs to the Solanaceae family and comes from Andean regions inhabited by the Incas in Peru, Bolivia and Ecuador (Filgueira 2007). It is cropped in practically all geographical regions of the world, under different cultivation and management systems. It is one of the most consumed vegetables worldwide and one of the main vegetables produced in Brazil, reaching the fresh or processed consumer market (Conab 2019). Most of the Brazilian tomato production is concentrated in the states of Goiás, São Paulo and Minas Gerais.
