Re: [Aroid-l] Intrageneric crossing?

Dear Marek Argent et al,

The author of the Alocasia-Colocasia cross was Dr H. Yoshino, of Okayama
University, Okayama City, Japan.  The crossing was confirmed by DNA
analysis and cytology.

It is possible that the sterile F1 generation has been maintained
vegetively, but this (historically valuable) material and the entire
aroid collection at Okayama may be in danger due to the likely
retirement soon of the collector. Materials from the collection would
require quarantining as part of any redirection - there has been little
effective control over the entry of viruses into the collection, and
during its maintenance (outdoors in summer, under glass in winter).

There managed to get very few seed and even fewer seedlings but they were successful. the cross was C. esculenta with I think A. odora but I'd need to grub out the proceedings to be be sure.

I know that they belong to deiierent tribes and have different pollination biology, however the Group says to me that the Japanese crossed Alocasia x Colocasia (the same tribe). Does anybody know anything about this Alo-Colocasia hybrid?
