Here's an update on from my earlier post, where I posted a picture of my kidney x northern? flower. Photo 1: Light red (pink) kidney beans and pod top left, great northern beans and pod top right, and the beans and pods from the F 1 in the lower half. I had a feeling the seeds would be black after seeing the dark purple stripes on the developing pod. Photo 2: Close up of the beans. I like the light flecking on the black background, and I remember somebody else showing a cross in another thread that had similar markings.

Welcome, and thanks for the pictures! For the crosses, are you using the trip and hook technique, doing full emasculations, or something else? andyb I found this helpful .pdf online Crossing Dry Bean (Phaseolus vulgaris) from the Dry Bean Breeding and Genetics Lab at Michigan State University and I copied their method, but I additionally emasculated the female. I found having the male donor stigma firmly hooked seems to be the key, and choosing a female that is just about to open had more pod set. I tried pollinating very immature female flowers (like in soybean), but alas almost always aborted!

It would be great to see additional pictures of everyone's crosses! I can now see there are several threads with posts of natural crosses with excellent pics.
I think I can push another generation this winter and attempt some four-way crosses. Maybe other gardeners online have some cultivars to recommend to add to this mish-mash of crosses? I think it would be great to swap some of my limited F2 seed with people willing to grow them out. Right now I am just having fun mixing the genepool for the sake of it, who wouldn't?

I work/study with soybeans, and I wanted try out my hand with some common beans the summer of 2016. After I learned black, pinto, navy, northern, kidney, pink, cranberry, and numerous others were all the same species Phaseolus vulgaris, I was fascinated! I chatted with a former post doc in my lab who worked with common bean quite some time, and he encouraged me to try out some crosses. They even have a unusual history of being domesticated twice from two separate wild gene pools, resulting in distinct Mesoamerican (small beans like black, navy, pinto) and Andean germplasm (large beans like kidney and cranberry) which makes for a great evening read, right? The complex domestication history of the common bean
I started with 9 varieties I grew from a Hy-Vee All Natural Nine Bean Soup Mix and the ingredients listed "Black Beans, Pink Beans, Pinto Beans, Small Red Beans, Navy Beans, Yellow Beans, Cranberry Beans, Great Northern Beans, Light Red Kidney Beans." A lazy way to get different beans, but I just wanted to test some out. I'd love to get my hands on more varieties! I planted 1-2 plants of each variety in pots and attempted crosses with at least two other varieties. Photo 1: A pink kidney bean flower on the left and a purple F1 kidney x northern? flower on the right. The northern had white flowers and white seed coat, so I think it's possible for the purple flower color to show up in the F1. Otherwise, it may be a hybrid with a black bean and I mixed labels, but my black F1's had dark veins at the throat of the flower, so I'm just completely unsure! I will wait for the seeds to develop. Photo 2: From left to right, navy x cranberry F1 pod, pinto x red F1 pod, and black x pinto F1 pod. I'm particularly fond of the navy x cranberry pod, the navy mother had green pods with no stripes. Photo 3: From left to right, same pinto x red F1 pod and black x pinto F1 pod from photo 2, now with a cranberry x black F1 pod on the right. Photo 4: The father red bean and mother pinto bean above and the F1 solid brown bean below. I would love thoughts of the proposed color genotypes for some of these beans. Photo 5: A half-sib circle: each bean is genetically half the bean adjacent. Going clockwise starting with the solid red bean on the bottom, and jumping every other bean are small red, navy (white), cranberry (red speckled), black, and pinto (brown speckled). The F1 beans are wedged between each parent. I have a few other F1 beans growing under LED lights right now and will add more pictures as they develop.
