there are some pics i took a few years ago on my blog on this page templetonsmedelania.blogspot.com.au/2012/12/male-sterility-in-carrots-some-photos.html . Could you collect seed into 3 bags - known good ones, suspect ones and reject ones, and next season plant bag-to-patch? That way if when you inspect them next season and you have rejected any good ones, you can restore them to the population.

Thanks a good idea... Hadn't thought of that. May just have to do in that.
All of the individual flowers I see don't have exactly 5 petals. They all are kinda crazy and mutated. I'm choosing the flowers with the most filaments and hoping. I'm also assuming that the ones with weak pollen vitality will cross with queens Ann lace and will come out white or light colored. I just thinned a couple rows of carrots from last year and I am amazed at how light colored they are. Bummer... To me that means sterility is rampant in my population.

Steev, I picked up as many oxheart lines as I could last year (although I assume they are all from the same grower considering everyone in the country suddenly had them) and so far they are all pretty sterile. I'm a big fan of them and will continue to try, no matter how futile.

That means they really can't be Oxheart, doesn't it?

Is that what that means? I have never had a hybrid carrot on my place and yet had infertility... How does it get into OP populations?
