This paper reports on the recent development of a new tomato variety, the Simi, which is resistant to verticillium and fusarium wilts and is recommended for trial on the southern California coastal plain and valleys near the coast. It is less fruitful than Pearson in the interior valleys. A good solid tomato with only a moderate-sized white core, Simi is especially promising for processing into paste and other concentrates on account of its fleshiness and deep red color.
Symptoms of the two wilt diseases, methods of experimental plant infection, evidence of occurrence of verticillium strains, and a description of the wilt-resistant Simi tomato are presented.
