Hi all, Noticed this the other day, sorry the picture isn't that clear - difficult shot. Anyway the growth is much thicker than the growth it originates off - my thoughts were possibly a spontaneous chromosome doubling... Would be interested in your opinions. It's was given to me as a wild type purple podded sheller - it dehisces when dry, so not much use. www.dropbox.com/s/8n57rlyy3ahc3wp/TetraploidL32.jpg?dl=0Cheers Steve |

More likely fasciation. Somatic polyploidy is really unusual.

Hard to tell from the photo, but fasciation is what it might be. I've worked with the "mummy" type peas that show fasciation regularly and in all cases the plant starts out normal and the stem gets thicker the higher up it grows. Always wierd to see such a large plant being fed by such a small stem at the bottom, but thats how it works.
Other peas are known to show it randomly because of environmental factors. Perhaps thats what you have. Only way to know is to save seed from that stem and plant it again.

keen101 (Biolumo / Andrew B.) This entire growth comes from a junction. Normal above and below. It's flowering now so will bag some pods to keep the vermin out and see what happens. Interesting though, as for environmental factors - there's a few of those. Growing peas through mid summer being the biggest one.

Thanks keen101 (Biolumo / Andrew B.), I've read about tetraploid peas (from a Russian paper maybe). Not too hard to do with the right agent. Sigh, if I was going to import there'd be a few things well in front of that. And saying that I can only barely keep on top of my current projects. |
