These were originally grown as a bit of an afterthought along a marginal dry bed next to a half shaded fence. I had returned from a lengthy winter holiday to find a mass of F1 plants with set pods, but because of weather conditions, some of the pods had sprouted or sprouting seeds in them. I just chucked a whole heap of what I thought were ruined seeds into a bed, and got a great germination.
The plants struggled, many only setting one or two weak pods, so selection was a bit difficult, but a few plants stood out, with big pods, and vigour. I bulk collected the yellows, and individually bagged the good plants, and grew them out in March 2013, along with 2 seeds from each of the rest of the yellows. This was not a great strategy - autumn weather didn't give me the great seed crops I had got the year before, and I was away on another extended break, and wasn't around to do a proper assessment. Luckly a friend collected and bagged the seeds for me.
This spring 2013, I sowed seed from some of the offspring of the best F2 plants as well as a couple of seeds from all the other yellows. This has given me a lot of plants to choose from, including some unlikely and subtle variations in the phenotypes.
So how to go about selecting from this big pool of candidates? I certainly don't have room to grow out another mass planting, and I'm probably far enough along the generation pipeline for some of the characteristics to begin to show some stability.
Since these plants are being grown to eat, flavour is a major factor. But I didn't select the parents based on their outstanding flavour - I rushed in, and just crossed everything with everything else, just to get started. A bit less haste might have been a good thing. So the flavour of these crosses isn't remarkable, just standard snowpea. Anything with chalky or dry-mouth feel is rejected. Which still leaves a large number of individuals to select from.
I've begun to think along commercial lines - what would reduce labour costs for someone growing yellow snow peas? In the first place, coloured snows are useful for anyone hand harvesting since the peas stand out from the foliage. But there is another characteristic which makes them stand out - literally.

The pics also show the light weight aluminium tags I use to label plants and crossed flowers - the embossing lasts even if the ink fades.

As luck would have it, there was considerable variation in peduncle length, from about 1 centimetre long, to almost 10 centimetres. Unfortunately there weren't any double flowers in the main F4 crop, but there were some in my F2 growouts of another line, my Golden Spring project which I wrote about in one of my recent posts. But the Golden Spring lines went in late, and there was no opportunity to cross the two yellow snow lines together to combine characteristics. Next season.
The double flowered characteristic showed up on some of my purple snow growouts - you can also see how the purple pods really stand out from the green of the foliage.
