Selecting for fruits without signs of pest/disease damage should therefore be selecting those healthiest individuals for the next generation.

It seems to me like fruits that grow more vigorously and are more free of bug blemishes are likely to have had more resources available to produce larger seeds than fruits that struggled for whatever reason: water, rain, sunlight, humidity, bugs, shading, timing, daylength, microbes, etc.... I can't envision all the things that might affect the growth of seeds, but I can envision that fruits from the same plant that are larger are likely to have devoted more resources into storing more nutrients into the seed. Seeds with more nutrients get a faster start on life, and often spend the entire season growing more vigorously than plants started from smaller seeds. The difference is sometimes dramatic on plants like beans, where some seeds can have perhaps 10 times more energy stored in them than other seeds produced by the same plant.

Joseph Lofthouse wrote:Another thing that I notice frequently in online forums is that once plants get fully grown that people have a hard time distinguishing one plant from another... They do things like plant a hill of squash, and then wonder why one plant is producing different colored fruits (or even different species of fruits) when what is really going on is that there are several plants growing together in the same place.
Joseph Lofthouse wrote:How selective I am with fruit selection depends somewhat on how desperate I am for seed. If I'm growing a rare or precious variety and it produces only a few fruits, then I will save seed from anything that it produces, no matter how bad looking it is.
John Polk wrote:I agree with Joseph.
I feel that if I want to produce the best plants, I need to save seeds from the best fruit.

I think of the third year as the magical year in a landrace development project, so I have great hopes for the field okra experiment. The first year I grew okra, less than 1% of the plants produced seed and the plant was up to my ankles when it got frozen. The second year, a few plants produced seeds, and they grew as tall as my knees. The third year, one of the plants was as tall as I am, and I had enough okra to take to the farmer's market. This year the tallest okra plant is about 8 feet.
Their descendants will surely vary depending on the pollination source for each apple, but that's random and didn't effect the apples in the generation I'm picking. Right?
Joseph Lofthouse wrote:But what if... The fruits started rotting because one of the seeds in the fruit didn't have a properly functioning dormancy mechanism, and the seed started growing while still in the fruit, causing the fruit to rot? I've occasionally seen that with tomatoes. I'm more likely to blame the rotting fruits on damage from insects, hail, or sunlight.

Anne Miller wrote:Thanks for the reply. So that is a possibility since teosinte is in Wildlife seed mixes or is that teosinte not wild? I don't know what was in our seed mixes or what is in my neighbors' mixes. I picked up some corn looking plants in our driveway but thought they were millet. I'll have to keep a eye out for corn looking plants when I am out and about. Since we came out of a drought the grass has grown so much that it is hard to see what all is growing around us.

Yesterday I picked two gallons of sweet crab apples from a tree that was growing without care in a public space near me. Fruiting was prodigious, so I was able to pick just the biggest prettiest fruit. Of course I'm planning to plant seeds all over my property.
But it's late in the season. There were mushy rotten fruits in many of the fruit clusters. I'd grab them and get four good crab apples and a handful of mush from the one rotten one that slimed in my hand under the pressure of plucking the other four.
There are probably genetics that govern the apples' hold time on the tree before they start to rot. But once again, I'm uncertain whether there's any selection pressure in my act of picking nothing but late-holding fruit. It seems to me that the genetics governing that should not vary from apple to apple; every apple on the tree has the same genes for that. Their descendants will surely vary depending on the pollination source for each apple, but that's random and didn't effect the apples in the generation I'm picking. Right? I'm so confused...
