A frost tolerant tomato.

A devastating greenhouse freeze led to one potentially valuable discovery. After 5 nights, or 40+ hours of subfreezing temperatures as low as -3.3 C a 2” seedling was found which showed no freezing injury. The survivor’s pedigree is F₄ (Moneymaker x Gemini x Adagio x Stupicke x Sonato x L. minutum). Later observations indicated this plant grew quite slowly, had 1 to 2 cm fruit, and leaves which wilted on sunny days. The wilting could be related to the frost tolerance, but studies need to be cone to discern why the wilting occurs and how this might relate to frost tolerance. Seed is available to those with interest.
