'Rio Grande' is a heat tolerant open-pollinated paste tomato variety. It was developed using traditional breeding methods by the University of California, and released in 1994. Though specifically bred for hot and humid southern climates, it has done well for us in zone 5b.

|Saving Seeds/Propagation||Allow fruits to fully mature before scooping out the seeds into a container. Let seeds and pulp ferment at room temperature for 2-5 days. To separate seeds from pulp, add water and allow seeds to sink to the bottom. Pour off the floating pulp and inviable seeds. Repeat until clean. Disinfect (optional) before drying at room temperature for 15-30 days, depending on humidity. Despite being primarily self-pollinated, methods to prevent cross pollination or adequate isolation distances should be used if producing true seed.|
