Genetic parameters of an interspecific cross between S. lycopersicum L. and S. habrochaites Knapp & Spooner

Abstract

T he main collection of allelic variants for breeding tomato ( Solanum Lycopersicum L.) is represented by its wild relatives, which evolved independently. It is important to study different sources of variation that are useful in breeding; therefore, the aim of this study was to evaluate S. habrochaites Knapp & Spooner as a source of different alleles by estimating the average degree of dominance, heterosis with respect to the mid-parent,
