Variety names now added.
Suspicious varieties currently listed as diploid but which look suspicious:
Set 1: Grenadier.
Set 2: Reverend Wilks.
Set 3: White Transparent.
Set 4: Peasgood's Nonsuch.
Set 5: Northern Greening.
The general trend for those varieties is their well-above-average (as a group) disease resistance and tolerance of challenging conditions. Just what we'd expect from a triploid variety with the extra chromosomes from which it would have a better chance of carrying a gene that allows it to cope better.
Four of them are listed as self-fertile. One is listed as a particularly good pollinator (which is unlikely, if it is triploid).
Or is it that the screwed-up genetics of a triploid allows the tree to produce seedless fruits?
