BREEDING NEW TOMATO CULTIVARS FOR PROTECTED CULTIVATION IN MILD WINTER CLIMATES |

| Abstract:
This work reviews the genetic improvement of tomato for low-temperature fruit-set and fungus-disease resistance. Parthenocarpic hybrids that produce fruits when minimum temperatures are less than 10°C have been bred, but their fruits tend to lack quality. The introduction of the cold temperature fertile pollen character into Lycopersicon esculentum seems promising and L. pennellii might be the most appropriate donor. Possible sources of resistance, the biochemical basis of resistance, and the genes involved in resistance to: fusarium wilt, fusarium crown rot, verticillum wilt, early blight, alternaria stem-canker, grey leaf spot, late blight, powdery mildew, leaf mold and corky root, are also discussed. | |
