TOMATO COLD RESISTANCE PRESENT STATUS AND FUTURE TRENDS |
| Authors: | R. Damidaux, J. Martinez |
| Abstract:
Genetic improvement of cold tolerance in tomato might facilitate extension of its geographic distribution and increase crop performance in open field cultivation, especially early in the growing season in temperate regions. Wild tomato species have been extensively explored by physiologists and breeders to improve tomato cold tolerance. This paper reviews techniques developed to evaluate chilling stress and population variability that may be useful for chilling tolerance. The effect of cold on germination, early seedling growth, plant growth, pollen production and parthenocarpic fruit set are considered. Some aspects concerning the physiology of cold adaptation are reported. The potential for future progress is evaluated from the perspectives of a breeder. | |
