Australis's blog: Iris Seeds from 2023 Season

Posted on Jan 18, 2024 8:06 PM

I only attempted a few crosses in spring 2023 and unfortunately only one of those was successful. However, the cross that did work was the one I am most anticipating (yay!) and the seed yield was pretty good!

65 seeds in the first pod and 21 in the second (the second bloom I pollinated was one of the last blooms), making for a total of 86 seeds!

Since 'Spendthrift' is a luminata and 'Ken Ware' a plicata, the progeny will have some combination of the plicata (pl), luminata (lu) and glaciata (gl) alleles. The ratio of offspring will help me determine how many copies of the plicata allele 'Ken Ware' carries. If my maths is correct, glaciata offspring will only be present if 'Ken Ware' carries only one or two copies of the plicata allele (which I think is the case); if 'Ken Ware' has four copies of the plicata allele, then there won't be any luminatas in the offspring (instead there will be a mix of plicatas and luminata-plicatas aka fancy plicatas).

I am looking forward to seeing what the results are like!
