From Tatiana’s TOMATObase:
This tomato was named by the former space engineer Igor Mikhailovich Maslov after his friend Vladislav Volkov, a Russian cosmonaut, who was killed during the landing of the Russian spaceship Soyuz 11, along with the other crew members. When Igor Maslov retired, he trialed more than 300 tomato varieties and he thought that Cosmonaut Volkov was the best. (This information was shared with Tatiana Kouchnareva by her seed exchange partner Valeriy Popenko of Semey, Kazakhstan, who has been growing tomatoes for more than 30 years.)
Introduced to Seed Savers Exchange in 1995 by Marina Danilenko, Russia.
