Thanks Joe! More data is always good. Based on what she shared, I would expect all of these to be yellow flowered. If I understand correctly, I think your seeds are L. henryi var citrinum x yellow seedling from (((L. rosthornii x L. henryi) x L. henryi var citrinum) x ((L. rosthornii x L. henryi) x L. henryi var citrinum)))?
The cross I made was with L. henryi var. citrinum 'Ypsilanti' & L. henryi from Jim Ault. Jim Ault's L. henryi came from Eddie McRae and is a very large/tall/strong stem. I made the cross both ways and am growing both groups of seeds. The wrinkle on this is that I am playing with treating buds with a Surflan/lanolin paste for the purpose of trying to induce the treated buds to breed as if they are tetraploids (produce unreduced gametes). I made this cross with only 1 flower from each plant and the buds were treated at a small size with this paste. There was some evidence that the buds were affected by the treatment and so there is the possibility that there could be a range of diploid, triploid, & tetraploid seedlings from this cross. The pod on Ypsilanti was a huge pod and was full of VERY large seed but the pod on the Ault henryi was not that different and the seed looked pretty typical and there was very little viable seed in the pod. I am excited to see what comes of this - I am expecting typical orange flowered seedlings but there could be some polyploids. It will likely be several seasons before I know what the outcome is. I didn't do a control for the experiment (didn't make the same cross on untreated buds) so I don't have anything to compare the seedlings to other than each other. I recognize that if I successfully produced tetraploid seedlings from this cross and intercrossed them that I would expect only 1 in 16 seedlings to be yellow [(1/4)^2].
