Resumen

ESTEBAN, Wladimir et al. Physiological behavior of tomato lines (Solanum licopersicum L.) generation F3 grown under conditions of salinity and boron excess. Idesia [online]. 2021, vol.39, n.4, pp.71-77. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292021000400071.

The productive diversity of the Lluta valley, located in the north of Chile, is conditioned by the high salinity and excess of boron present in the soil and irrigation water that can affect the physiological behavior of crops, requiring the use of tolerant hybrids or of local varieties adapted to this condition. To take advantage of the potential of local germplasms, regarding their tolerance to salt stress, a participatory plant breeding work has been carried out using the local parent "Poncho Negro" (TP 1 ) and two commercial tomato hybrids (TP 2 and TP 3 ), generating new lines that could be potential altern^tives to the use of commercial hybrids due to their greater tolerance to the stress present in this valley. In this work, the behavior of these tomato lines (generation F3) and their parents was evaluated in the soil and water conditions of the Lluta valley, confirming the high tolerance of the TP 1 parent to this type of abiotic stress. According to the evaluated parameters, T 7 would be one of the lines that could best develop in this valley, maintaining the salinity tolerance characteristics of its parent TP 1 , becoming an alternative for this saline valley.
