Grey captions say what stands behind that particular figure. Breeding, growth habit and fruit characters carry no caption because they rest on the record's sources as a whole rather than citing their own; closing that gap is ordinary outstanding work, not a finished job.
Origin & history
A Russian heirloom bearing small mahogany plums in heavy clusters, sweet enough for snacking and dark enough to make a strikingly colored sauce.

Against the rest of the tomato database
Where this variety sits among every tomato we hold a comparable figure for. Position is not merit: earlier is not better than later, and hotter is not better than milder. Only cultivar-level figures are compared, never trial results, and maturity is only ranked against figures counted the same way.
later than 70% of the 258 tomatoes we hold a figure for. None of these figures state whether they are counted from sowing or from transplant, so they are ranked against each other on the assumption that suppliers use one convention, which is not something any of them says.
Traits
Disease resistance
No documented disease resistance, typical of heirlooms and older open-pollinated varieties. See tomato diseases for the cultural playbook that fills the gap.
