Better for most of us to just put in the time and effort with conventional seeds than develop our own. ?There's lots of heirloom seeds out there and most gardens would benefit from more labor input and more educated gardeners. At least, that's where I am. I'll save some seeds now and then but I'm just not experienced enough to justify the efforts or even know that the properties I desire aren't in an established cultivar.

Perhaps, taking advantage of this tendency, one could harvest as if they were all to be eaten fresh, until a certain time. This time would be an estimation of when the first frosts are due. Stagger the dates by a week or two. The object being to allow some of the plants to go through at least one frost before the seed is viable. Seeds from those plants could then be saved to continue the 'hardening off' process in next years crop. After a couple of years, you should be growing plants much more likely to endure the worst that your climate can offer. These would be a 'localized' strain, the forerunner to a land race. A huge step towards sustainability.

They establish their root systems before the frosts put them into dormancy. They just sit there all winter, looking half dead. In the spring, once the soil has warmed to the right temperature, they resume right where they left off in the autumn. I have also found this to be the time that the first spring planting can begin; the plants have told me that the soil is 'just right'. With this technique, I have enjoyed fresh peas from last years starts a full month earlier than my neighbors, and my first spring planting usually beats theirs by a couple of weeks.

You mention acquired traits. Do we have a thread on this already? I would love to learn more about it.

There are some things that are not covered. For example, there is recent research that has found that fruit trees sometimes exchange genetic material at the site of a graft, and then send up adventitious shoots. This relatively unusual form of hybridisation may be a source of unique varieties, if you are lucky combining the best properties of both the rootstock and the scion (or, of course, something like a crab apple on a stunted, disease-prone root, but such are the risks). The frequency with which this occurs is unclear. The strategy of planting lots of tree seeds and selecting the best ones is a slower, brute-force approach, but can get results. These aren't major weaknesses (the former is based on recent research; the latter barely counts as crop breeding), but may be additional techniques to think about.

Is this essentially a "sport" then? That's quite interesting. I think I've seen this happen on some of my grafted plants.
Neil Layton wrote:The other relates to albedo management. https://permies.com/t/54823//talk-albedo There is still a lot of science to be done in this field, and some of it is talked about in the link, but there are opportunities to increase the reflectivity of plants in order to reflect more unwanted light (and thus heat) safely back into space. This is a complicated subject, and it seems that not enough is yet known about it. but there is work we can be starting on.
I have gone to look for myself. If I should return before I get back, keep me here with this tiny ad:
