Bean breeding & pollination
...indoors on a budget
The following pictures and short videos show the steps to bean pollination (here it was done indoors - no greenhouse needed) in order to create crosses between two varieties.
One can use it as a guide in summer too.
Have your tweezers ready!
I believe that knowledge should be shared at a reasonable cost or even free whenever possible. But in this world of ours almost nothing really is completely free. Our tiny seed company is still young and does not provide us with enough funds for both of us yet. Locally, we like to barter first (like getting manure, compost or leaves for seeds or vegetables) but we still have to buy things.
So if you like, feel free to share this web page and our online store to friends who may be interested and help us grow a little. Photos and videos by Hadashah Hétu, 2021, please cite author if using.
Thanks a lot!
Bean Flower Anatomy
The flower bears both male (stamens) and female (pistil, ovaries) parts. Following pollination, the bean pod will develop from the base of the curved pistil which is located inside the keel (a spiral-like structure). The pistil protrudes partially when a slight pressure is applied to the wings, such as when a pollinator lands on the flower.
Standard or Banner
First, find an immature, unopened flower. (Around 2 days before opening or anthesis). This flower will be pollinated later and develop the pod.
The external part is the standard which overlaps the other structures.
Remove it slowly to expose the keel and the wings.
