I have a tomato that I seed every autumn since 3 or 4 season. It is not the best one but my first volunteer. So i keep it. It is very early in germination and bloom but ripening is longer than usual. First bloom on 1st of May but first ripe fruit only at the end of August.... This year a different more vigorous type showed up . Will see how this strain will develope over time. Usually I smash the fruit to spread the seeds but even whole tomatoes that drop on the ground germinate as a bunch of seedlings every spring.
A few will outgrow the others and become mature plants. As it is a selfpollinating type it couldn`t suspect true evolution, only within selection what is is given to this line. Would be nice if it could becomes an outcrosser.
I started at least autumn seeding with 2 other lines. One is my Late Blight tolerant strain. The other one is the only tasty grocery store variety I know. It is within it is F3 now and is very sweet this year after being a very bland type last season. LB strain is very late but healthy. Leaves are still dark green and show nearly no infection with other diseases. I like it.
There nearly no LB pressure this season.
