Violets: Down below is a second generation violet seedling from the first generation hybrid Viola X cooperrideri. The F1 hybrid was from a hand pollination of Viola striata by pollen of Viola walteri. I'm encouraged that a few of the F2 seedlings (like this one) have been blooming fairly well in the Fall too. I'm considering putting a little selective pressure on this population to try to push them toward all summer bloom. Actually all of these violets DO bloom all summer but when the day becomes a certain length, they switch over to producing small (non-showy) cleistogamous flowers. I'll just need to select for longer and longer daylength requirement (for that switch-over) and then they'll have the pretty chasmogamous ones all summer.
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.
