Bolters in my carrots

[Medbury Gardens]

The Canterbury province where i live is one of the largest carrot and radish seed grow areas in the world, but why do us locals have put up with only been able buy such inferior seed as whats in the photo (unless we grow our own).

I planted a 3x1 metre bed of Manchester Table from Yates seeds(Australia &NZ Ltd), whats in the photo is about 10% of what i have pulled out so far and wont be the last i would think.

The way that the home vegetable growing market is growing recently world wide,these large seed companies can`t keep selling these poor quality floor sweepings much longer.Is this a similar problem that other down under folks have experienced from such large seed companies like Yates?
