Heatmaster holds its own in hot Southern gardens, where temperatures are frequently high. A determinate hybrid tomato, plants produce strongly oblong fruits perfect for halving or quartering into salads. Medium-size fruits typically ripen in roughly 75 days. Heatmaster performs well as a fall crop in warmer zones. Plants are resistant to alternaria stem canker (Aal), gray leaf spot (Ss), verticillium (V), fusarium (F), tomato mosaic virus (ToMV), and Southern root-knot nematode (Mi/Ma/Mj).
