Morphoagronomic characterization of tomato lines (Solanum lycopersicum L.) resistant to begomovirus
Main Article Content
Abstract
The present work was developed to evaluate the in order to characterize morphoagronomically the phenotypic variability in 16 tomato cultivars, including 15 cultivars are resistant to begomovirus from Taiwan and the analysis of these cultivars to the circulating virus isolated in Cuba. For this, 20 morphoagronomic characters related to the plant were evaluated, the fruit and the phonological stages. In addition, begomovirus resistance was evaluated by the severity of the disease caused by infection of TYLCV-IL under uncontrolled conditions. For the morphoagronomic viewpoint, a phenotypical variability regarding morphoagronomic characteristic was detected, grouping the cultivars into four main groups. Except for the susceptible control, all the evaluated cultivars were asymptomatic to the virus, confirming the prospects for their use in plant breeding programs for obtaining new hybrids and cultivars resistant to begomovirus.
