For me, cowpeas (and yardlongs, which are a sub-species) are less prone to crosses than Phaseolus beans. In 15 years of seed saving, I have only seen one cross, between two yardlong beans. I expected to see more crossing, given the larger, more open flowers of cowpeas. It may be that in my Northern location, I lack the proper pollinators... all I ever see working the flowers are wasps, which are poor pollinators.To your knowledge, does this apply to cowpeas as well? I'm just thinking of back when I used to get my cowpeas out of the bean mix I would buy at the Korean grocery store (though it was grown in China).
The appearance of those cow peas sure LOOKED like what one would expect of a cross (or more accurately of a cross breaking down). The commonest coat color was a mottled eye. But some had a solid brown eye, and some were mottled all over (or mottled with a white patch on one end). It always LOOKED like the browns and the mottled all overs were ancestors, and the (commonest) mottled eyes were the result of a cross.
Though all seem to come true to themselves when planted, so maybe there is/was another explanation)
There are many Southern gardeners here who grow cowpeas (I know they are commonly just called "peas" there); I'd be interested to know if crossing between different cowpeas is more frequent in warmer climates.
