The Inheritance of Chilling Tolerance in Tomato (Lycopersicon spp.)

Abstract

During the past 25 years, chilling tolerance of the cultivated (chilling-sensitive) tomato Lycopersicon esculentum and its wild, chilling-tolerant relatives L. peruvianum and L. hirsutum (and, less intensively studied, L. chilense) has been the object of several investigations. The final aim of these studies can be seen in the increase in chilling tolerance of the cultivated genotypes. In this review, we will focus on low-temperature effects on photosynthesis and the inheritance of these traits to the offspring of various breeding attempts. While crossing L. peruvianum (male symbol) to L. esculentum (female symbol) so far has brought the most detailed insight with respect to physiological questions, for practical purposes, e.g., the readily cross ability, crossing programmes with L. hirsutum as pollen donor at present seem to be a promising way to achieve higher chilling-tolerant genotypes of the cultivated tomato. This perspective is due to the progress that has been made with respect to the genetic basis of chilling tolerance of Lycopersicon spp. over the past five years.

Contrasting effect of dark-chilling on chloroplast structure and arrangement of chlorophyll–protein complexes in pea and tomato: plants with a different susceptibility to non-freezing temperature

“…Low-temperature treatments of CS plants like tomato aVect the thylakoid electron transport, ribulose-1,5-bisphosphate carboxyleas/oxygenase (Rubisco) and other enzymes involved in the carbon reduction cycle and control of stomatal conductance (Allen and Ort 2001;Venema et al 2005 and references cited in both). However, plants chilled in the light and in the dark revealed substantial diVerence both in the scale of inhibition of photosynthesis and the primary mechanisms involved (Allen and Ort 2001).…”

Effect of extreme temperatures on powdery mildew development and Hsp70 induction in tomato and wild Solanum spp.

“…are chill-tolerant and survive low temperatures between 2°C and 15°C, however they are freezing sensitive. High altitude accessions of S. habrochaites harbour the superior tolerance to low temperatures (Venema et al 2005). The symptoms of low temperature injuries include the cessation of growth, wilting, chlorosis, and necrosis.…”

Grafting as an Alternate Tool for Biotic and Abiotic Tolerance with Improved Growth and Production of Solanaceous Vegetables: Challenges and Scopes in India

“…Wild species of tomato have wider temperature thresholds than the domesticated lines and can be used as root stocks (Venema et al, 2005). The grafted plants exhibited greater quantity of flowers, trusses and fruit production in when compared to non-grafted controls at temperatures considered non-optimal for the scion.…”
