In recent years, there have been the "shock" discovery of a number of old varieties which were assumed to be diploid but have since been proven to be triploid by genetic testing - Ashmead's Kernel being the real shocker for nurserymen.
I remain convinced that there are still many "undiscovered" triploids out there, which we're still assuming are diploid and which we may be relying upon as pollinators when actually they may be poor pollinators and explain why some people have pollination problems or irregular cropping.
But if we were to take the time to look at them closely - their leaves, their blossom, their fruit, the seeds in their fruit and other features, I think we'd soon say "of course it's likely to be triploid - it certainly looks like one even if it hasn't been formally confirmed as such!"
So I acquired a few pictures of apples for a little bit of a fun test.
Each post with pictures below will contain one variety known to be diploid, one known to be triploid and one which I am suspicious about.
Most of the varieties are reasonably well known, even if not in the best-seller lists nowadays. But I have removed their names so as not to bias opinions.
I would like forum members to take a guess as to which one is which in each of the postings (no need for names: just state which you think is triploid, which is diploid and which one is listed as diploid but I suspect might one day turn out to be triploid).
Maybe we can also have a debate.
In a few days I will reveal the exact names of each variety.
Please have a go at guessing, even if you're wrong. If you can explain why you thought a certain picture was diploid or triploid that would be even better.
Thanks,
