Anyone seen this before? (Wheat)

[ICRFarming]

Gonna start harvestIng wheat soon, and saw these split wheat heads. Can anyone tell me if they've seen the same thing and possible causes of this mutation?

Never seen anything like that before.

What are the grain sizes like in the secondary spikelet? I've seen a much reduced version of this in JB Diego wheat (originally bred in Germany as a milling wheat) but nothing like the size of those.

Hi.
I've seen barley like that.
Believed to have been caused by hormone type weed killers applied at wrong growth stage.

5020 man.

That would be my guess too, @richard hammond ?

Just had a quick read of an American paper on the subject and it suggests this https://webapp.agron.ksu.edu/agr_social/eu_article.throck?article_id=1290 although majorly deformed rather than appearing mutated.
Another suggested glyphosate drift injury causing similar.

"Going to start harvesting wheat soon.." heck we only just finished drilling yesterday!

I have seen heads of JB Diego with a kink but not produce a second spikelet at that point.

Might be useful to know what’s been applied to it? And at what gs?

two heads are better than one

I have seen this before years ago at a CPB wheat breeding station. It was a genetic mutation where each grain site produced a mini ear. Strangely it was never taken to commercial bredding lines!

I have seen it several years ago, we blamed a particularly heavy frost until we remembered that it was about 7th generation seed.....

I as thinking this, might be the cause of farm saving for too long and seeing the plants doing strange mutations as the purity gets less and less. if it was new seed then I'd go to some kind of herbicide damage.

Sorry, been off for a week, but before I was I posted a photo on Twitter.

Received these replies.

Late application of CMPP will do it
