For all of you who would like to follow out-breeding rate in your Vicia faba. Or need to select hybrids at early time point.
"The pollen donor genotypes carried markers as follows: A line from cultivar Minica 1.1, with the presence of a melanin spot on the stipulae (dominant over its absence), a line from the cross Minicax 434/'77 and a line from the cultivar 'Ltineburger', both with black seed coat colour (dominant over brown) and 'Populatia locala' with anthocyanin-containing seedlings (dominant over anthocyanin-free)"
My favas are mix of 4 named varieties from seeds shop (Bartek, Meteor and 2 more that I can't recall names) and are all recessive for all of these traits. Is there anyone having "melanin spot" or anthocyanin showing seedlings phenotype in mongrel population and willing to sell/exchange/present seeds?
I have very good success with favas. It is the best cropping specie for me with easily 1:30-40 ration (seeded:harvested) depending on year. There are always some plants showing even higher ratio. I'm interested in adding some easy to track genetics to my population and to see how much mixing is there and increase their adaptiveness even more.
Just the bean itself is all I was thinking of not the plant. I may need to observe more closely next year.
Seed coat is determined by genetics of mother plant. Same plant, same seed coat color for all beans. In order to identify segregation you would need to plant family groups, wait for plants to set seeds and only then you would be able to say was there something or not. That's why I'm looking for anthocyanin in seedlings or "melanin spot", they can be scored with first above ground parts or first true leaf, respectively. If you have limited space, very useful markers (at least, when compared against seed color).
Estonia, eh? I'm sure your experience will be valuable to some of our northern contributors. The broader our field of expertise, the better. Unfortunately, it seems my NorCal climate is becoming less "Northern" than it used to be, not that it was ever very much so.

Grew my fava grex again this year. Did well with almost total neglect. I took the seeds produced last year, spread them out on the base of two old piles, one of sawdust, the other bark. Then rototilled them in. Got a lot of favas back. Still haven't picked them all. Picked more just day before yesterday.
Snow is unclenching. Last weekend I spotted one fava seed looked about to sprout laying on the surface from last year. Nudged a bit of soil over it. Curious to find out if any fava seedlings or seeds survived to volunteer.
