I have a friend who bought a house/farm lock, stock, & barrel.
I inherited the seed cache...some older, some not as old.

They are largely well marked. However the pictures below are from beans in a tattered paper bag. The bag appeared to be marked "Roma 192". I've been looking for a couple of hours online and can't seem to find this either through text searches or image searches. They appear to be treated (the pink colors/patterns) but with what?

So, does anyone know Roma 192?

Is anyone familiar with the treatment?

Roma 192 was probably an experimental variety never release to the public. The pink stuff is a Captan based fungicide which as been used in treating seed for many years. There are newer treatments on the market now, dyed in many different colors. The colors are used as a warning that the seed has been treated. It is very useful in protecting the sprouting seed from several fungal rots.

I t-h-i-n-k those are an Italian bean cultivar called Fagiolo Romano (Roman bean). Despite the name it's a cultivar from Tuscany, in the specific the area between Arezzo and Florence. It is now extinct or very nearly so since it is one of the old fussy Italian cultivars like Zolfino that only grow in very specific conditions.

I have no idea why they are called Roma 192: Roma 2 is a very widespread green bush bean in France and Italy but it looks nothing like this. Perhaps they were obtained as a gift or on trade from Italy and mislabeled or some seed company tried to repackage them under a catchy name. It happened very often in the 90's when we got hundreds of tomato/watermelon/cucumber/etc cultivars from the former USSR and seed companies just renamed hard to pronunce cultivars or simply invetd names for unnamed local cultivars (reas: Sasha's Altai).
