Roma
In 1955, the Roma tomato emerged as a hybrid variety, believed to be a cross between the Pan American tomato and the San Marzano. Contrary to its name, Roma tomatoes did not originate in Italy. Instead, they were carefully developed by the USDA using traditional breeding techniques. They made their debut in the American market in 1955 and were officially designated as an heirloom tomato by 2005. While precise records of their breeding process are lacking, it is widely speculated that they are the result of a cross between the San Marzano and Pan American tomatoes. 'Pan America' was developed by William S. Porte at the USDA's Plant Industry Station, Beltsville, Maryland. It originated from a stabilized cross between the 'Marglobe' tomato and a wild red currant tomato found on the Pacific coast of Peru, South America. 'Pan America' is known for its high resistance to Fusarium wilt and nailhead rust, and it was introduced in 1941.
Roma tomatoes distinguish themselves with their shorter, plumper, and more vibrant appearance compared to San Marzanos. These 4-5 ounce fruits offer a dense flesh with delivering a savory flavor profile with a hint of sweetness. The "Roma VF" variant took center stage in seed catalogs. Developed by scientists from the USDA's Agricultural Research Service (ARS) based in Beltsville, Maryland during the 1950s, is known for its resistance to fusarium wilt. Although they are considered open-pollinated rather than hybrid varieties, Roma tomatoes have undergone continuous refinement to the extent that most Roma tomato plants are now resistant to verticillium and fusarium wilt.
