As Walter says, there's a reasonable chance they will be close to tetraploid, possibly with extra chromosomes. I think there is a lot of good info about this topic in the archives - maybe search for 'triploid' to get started. Or maybe amphidiploid. Lots of good stuff from Sharon McAllister and some others.
The crosses I've made with diploid I. pallida using tetraploid pollen have given some seedlings that are fertile enough to set bee pods (I haven't tried many intentional crosses on those seedlings).
45 surviving seedlings this year from S1bwhpk:(S1bwh:(S1:(diploid - I. pallida x tetraploid - MULBERRY ROSE) x bee) x bee) X TRANS ORANGE.
Another batch of seedlings from S1bwh X VIZIER (all discarded - some were cute, but rot prone & none worth keeping). One from S1bwh X SEAKIST germinated this year, hoping for more from that cross next year.
If one parent is a known diploid and the other is presumed non-diploid, does that mean the resulting seedling is at best triploid? Does that mean my seedling will be sterile, for all intents and purposes?Christian
