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.
在过去25年里，栽培种（冷敏感型）番茄（Lycopersicon esculentum）及其野生、耐冷的近缘种秘鲁番茄（L. peruvianum）和多毛番茄（L. hirsutum）（以及研究较少的智利番茄（L. chilense））的耐冷性一直是多项研究的对象。这些研究的最终目标是提高栽培基因型的耐冷性。在这篇综述中，我们将重点关注低温对光合作用的影响以及这些性状在各种育种尝试后代中的遗传情况。虽然到目前为止，将秘鲁番茄（♂）与番茄（♀）杂交在生理问题方面带来了最详细的见解，但出于实际目的，例如就容易杂交的能力而言（目前以多毛番茄作为花粉供体的杂交方案似乎是培育更高耐冷性栽培番茄基因型的一种有前景的方法。这一前景得益于过去五年里在番茄属植物耐冷性遗传基础方面所取得的进展。
