  hybridization of Amorphophallus kiusianus
From: "StroWi at t-online.de" <StroWi at t-online.de> on 2018.03.04 at 02:23:28(23815)

Aroiders,

will pollination of a A. kiusianus with A. dunni pollen result in hybrid seeds or will the apomictic trait of kiusianus reign totally?

Hi Bernhard;

We pollinated the reportedly apomictic Amorphophallus henryi with A. dunnii pollen and got seedlings with intermediate traits, so it is possible to overcome maternal
apomixis. We did the same with the apomictic Hosta ventricosa, finding only one species, Hosta yingeri whose pollen would overcome the apomixis of the maternal parent.

Hi Tony,

that's an interesting observation with the Hosta!

I was not aware of this apomixis, but just learned that it is usually apparent in several families including a gesneriad, Titanotrichum oldhamii which most frequently propagates through above-ground propagules and is seldom fertile. However, it is not necessarily consistent and does vary between populations in native Taiwan.
