From Tatiana’s TOMATObase:
Summertime Gold reselected. The original release of Summertime Gold showed too much of a similarity to Dwarf Mr. Snow, likely due to some lingering segregation of genes. Selection work carried out by Craig LeHoullier and Lee Newman resulted in this improved version, exactly what project members hoped for with the original release of Summertime Gold. The starting seed sample was grown out and supplied by Bill Minkey of Darien, Wisconsin (WI MI B) in 2014.Introduced commercially by Heritage Tomato Seed in 2015.
