Tomato and its processed products are one of the most widely consumed fruits. Its domestication, however, has resulted in the loss of some 95% of the genetic and chemical diversity of wild relatives. In order to elucidate this diversity, exploit its potential for plant breeding, as well as understand its biological significance, analytical approaches have been developed, alongside the productio...

ABSTRACT We used molecular markers to identify quantitative trait loci (QTL) that confer resistance in the field to Xanthomonas campestris pv. vesicatoria race T1, a causal agent of bacterial spot of tomato. An F(2) population derived from a cross between Hawaii 7998 (H 7998) and an elite breeding line, Ohio 88119, was used for the initial identification of an association between molecular mark...

What causes the domesticated tomato Solanum lycopersicum to have sweet, juicy red fruit and large, compound leaves with narrow-tipped leaflets while its distant wild relative, the Peruvian Solanum pennellii, has small, soapy-smelling green fruit with an unpleasant flavor (Matsui et al., 2007) and small compound leaves with thick, rounded leaflets (see figure)? Thoroughly answering this question...

Whiteflies (Bemisia tabaci) are a serious threat to tomato (Solanum lycopersicum) yield and production since all varieties highly susceptible this insect. The wild Solanum pennellii shows resistance towards whiteflies infestation due the high contents of acylsugars presents in its leaflets, which is not observed S. lycopersicum. Thus, plants from F2BC2 population derived cross between cultivar ...

To be considered drought-tolerant, a tomato cultivar is required to present some level of tolerance at all developmental stages plant growth. Since drought stage-specific phenomenon, genotype assessment must performed separately stages. In this study, we used multi-trait index based on factor analysis and genotype-ideotype distance (FAI-BLUP index) properly rank 49 genotypes according their str...
