Resumen:
Eighteen tomato RILs selected for fruit weight and shelf life were obtained from an interspecific cross between the wild accession LA722 (P, Solanum pimpinellifolium) and the Argentinean cultivar Caimanta (C, S. lycopersicum). Sequence Related Amplified Polymorphisms (SRAP) are a new kind of molecular markers that preferably reveals coding DNA regions. Diallel crosses allow studying the inheritance of quantitative traits and presently they could be also applied to molecular markers. Procrustes analysis (PrCA) is a multivariate approach that measures the consensus among two sets of data in a given population. The objective of this work was to apply a PrCA to a diallel cross among five of the selected RILs. PrCA among SRAP markers and quantitative traits evaluated in this diallel cross of selected tomato RILs allowed to verify the consensus among both sets of data in this novel genetic background.
