Andrew’s Pea Crossing Method

This is a Pea Breeding method i (Andrew Barney) came up with that i think increases success for at least two reasons.

The first is that i believe here in my climate with dry air it is important to mimic the protective covering of the flower to help keep the pollen or style/stigma from drying out before being pollinated or pollen being washed away in the rain. In my climate the air can be quite dry and the high altitude with intense sunlight tends to wick away moisture quite easily. These tiny pea styles are quite delicate and seem to dry out so quickly that they can dry out before pollen has been able to set seed. The second, is that i suspect that the different ovules that have the potential to create a seed do not all mature at the same time, if this is correct then it is important to keep enough pollen on the stigma as long as possible over several days for each seed to be pollinated and grow. And finally, it just seems to mimic everything about how a pea flower would naturally self pollinate. Sometimes it’s best to just imitate nature as sometimes nature knows best.

Though i have not done extensive recording of statistics i believe that this method here in my garden has at least doubled, maybe tripled the amount of mature cross-bred pea seed. My method is a bit odd looking at first, but in my experience it works MUCH better. On average from what i can tell you usually get about 1-2 peas per pod with the “paintbrush method”. No more than 4. With my method i’d say you get on average of 4-5 peas per pod, with the potential of a whole pod 6-8 peas depending on your variety. So i’d say I’ve at least doubled the success rate, maybe even tripled it.
