Salt Tolerance in Lycopersicon Species .2. Genetic-Effects and a Search for Associated Traits
Eleven quantitative traits, mostly related to tomato plant growth and fruit set, and their association with salt tolerance in terms of fruit yield under a 171.1 mM NaCl treatment have been investigated in 206 progeny derived from an interspecific hybrid, L esculentum x L. pimpinellifolium, by self-p...

| description | Eleven quantitative traits, mostly related to tomato plant growth and fruit set, and their association with salt tolerance in terms of fruit yield under a 171.1 mM NaCl treatment have been investigated in 206 progeny derived from an interspecific hybrid, L esculentum x L. pimpinellifolium, by self-pollination. None of the traits were highly correlated phenotypically to salt tolerance; however, the immunologically-detected presence of peptide 2' was significantly associated with high total fruit weight (TW) and number (FN) under saline treatment. Broad-sense heritability was estimated for these two salt-tolerance components as 53.44 and 72.59 %, respectively. Non-additive gene effects, which have to be considered in a breeding program for salt tolerance, have been detected in TW, FN and in average fruit weight (FW). Given that different types of gene action have been found depending on the presence or absence of a high NaCl concentration in the nutrient solution, a different set of genes, or genes, differently regulated, must be involved in the expression of TW, FN and other fruit-related characters depending on this environmental condition. |
