Here's that F2 seedling from the cross of Viola striata X Viola walteri that I posted a few weeks back. The picture isn't great, but at least you can see how well it's blooming today (Nov.19) - I'll have to move this one to a better spot and try to collect seed, so I can select for even earlier Fall bloom.The Covered Wheats - More primitive wheats that do NOT thresh free of the glumes/hulls that surround the seed while on the stalk. More modern wheats are all free-threshing. Their seeds fall out completely naked of these coverings. These are four covered wheats that I've been maintaining by growing out a batch every couple of years. This year I also used the Black Emmer and the Spelt in some crosses with some free-threshing wheats. I'll be sure to blog about those next Spring when the hybrids should be heading.
The top two are diploid (2N=14) Einkorn wheats.
Bottom left is a tetraploid (2N=28) emmer wheat - the primitive relative of the durum (macaroni) wheats.
Bottom right is a hexaploid (2N=42) spelt wheat - the primitive version of the common bread wheat.
