Keeping records of crosses is really time consuming, but like Michele and Fred note, even more helpful than cultivar listings (especially since we have ATP to help with database and plant lists to keep track of all that - and they print out very nicely!). I admire and follow the practice of noting pod x pollen on the plant at the time it is crossed, and recording it for registration use later. I like being able to track what breeding choices have resulted in pods - I have one this year that is setting pods from both tet and dip pollen, and might have lost track of whether the crosses were "taking" otherwise.
It sounds like your surviving 2013 seedlings will have been very narrowed down to a super hardy group, Michele. A tough way to weather nature's culling out of desired crosses, though, I know. I started with 300 seedlings in 2012 and after their first summer in the blast furnace garden, with a few additional losses over time, was left with perhaps only 30. Still, I am glad to see how well those 30 have done and have no worries about their tolerance for heat and drought.
Good ole pencil and paper, always improved upon, never replaced. Though I do relish getting that written-down pollination and seedling info into my excel sheets to track notes on success rates and how the seedlings develop.
