Offered to help clarify source and F-generation of Indigo Apple germplasm currently offered at several seed sales sites:

"Indigo Apple is a rare OSU Blue cross selected five (5) generations for color and taste. This tomato has supreme shock value. Thank you PKS Heirlooms for the original cross! The unripe green fruit will show lots of purple, which is brought on by the sunlight, will eventually turn almost a true black. This is caused by the high anthocyanin level (antioxidant found in blueberries). This tomato has a good sweet tomato flavor. I am one of three people in the world with this particular F-5 cross." (posted on Wild Boar Farms website, circa April 2014)

For more information regarding the selection and stabilization of Indigo Apple tomato, I suggest contacting Brad Gates, at at wildboarfarms@hotmail.com.

Meanwhile, and with regard to the possibility of obtaining F5 generation with an "OSU Blue" outcross when Indigo Rose was only released 3 years ago, keep in mind that "OSU Blue" germplasm escaped the OSU laboratory circa 2008, and in a form not exactly the same as Indigo Rose, which is what Dr. Myers wished to release as the "stabilized" version of P20.

The PKS Heirloom entity (represented by Brad Gates as the source for the original cross subsequently selected year after year by Brad until his release of Indigo Apple) obtained "OSU Blue" seeds circa Fall 2009 or Winter 2010, from a source in England, and possibly in a form that already showed an outcross that had occurred in a certain garden (which at this time shall remain unnamed) in 2009, and which germplasm produced what became known as "OSU Blue Large" (google it), obviously an outcross due to 1) the larger size and particular shape of the tomatoes, and 2) the fact that the vines were indeterminate, while the original seed sent to England the previous year were from a fully determinate bush that produced 2-ounce, round to plum shape fruit.

Therefore, I submit that Indigo Rose essentially is an attempted stabilization of P20, while Indigo Apple most likely is the F5 or greater selection from a possibly accidental outcross or maybe a purposeful outcross of an accidental outcross rather than what TGS is calling "a variation" of Indigo Rose.
