In general, the more of a pain in the ass that it is to hand pollinate a crop, the more likely that the hybrids are created through male sterile lines. Vegetables that self pollinate generally aren't. Vegetables that produce copious seed from large, accessible flowers generally aren't. Vegetables that produce few seeds from tiny or inaccessible flowers generally are. So, you won't find many sterile peas or beans or tomatoes because they will self pollinate and are also accessible to hand-crossing with reasonable yields. You won't find many squash because they have nice big flowers and one cross produces tons of seed. You will find plenty of umbellifers and brassicas that are male sterile because the many tiny flowers are simply too difficult to cross by hand.
Growing where temperate rainforest meets the sea (WA coast): Jan avg low temp ~34*F, Aug avg high temp ~69*F, ~111 annual inches of rain, but only about 15 inches May-Sep, salt air, lots of wind.
Merchants are not always clear about whether they are selling hybrid seed so even if they are not listed as being hybrids they might be anyway. I have grown some onion hybrids that are both male sterile and female sterile.
I've noticed that some peppers produce only a couple of seeds per plant: essentially sterile.
Common sterile crops may include potato, pineapple, banana, orange, grapefruit, watermelon, grapes, summer squash, garlic, potato onion, (parthenocarpic) tomatoes, and eggplant. Seed vendors typically use the word "seedless" to describe them.
Silt/clay, high-altitude, super-arid, sun-drenched, irrigated-desert garden. Cold radiant-cooled nights. ~100 frost free days. Grow most of my own locally adapted landrace seed. GDD10C ~1300. Buy my book or subscribe to my newsletter at Lofthouse.com.
I'd disagree on the parthenocarpic tomatoes being on this list. In my experience they aren't sterile and will produce seeded fruit under normal tomato pollen viability conditions, at least the varieties I've grown. Most of the parthenocarpic tomato varieties I'm aware of are OP.

wilscase: I'm a graduate student at Oregon State and have been working with populations segrgating for different color genes such as the B gene in Cucurbita. I'm curious if anyone has experience with crosses in Cucurbita maxima between grey blue types and orange?

wilscase: I have been backcrossing to the grey parent for 4 generations and have finally selfed the heterozygotes (for the Bmax gene) the populations have segregated for diffuse bicolor (pink/blue, orange green), blue green, blue, green, pink (salmon) and orange
Oct 18, 2022 21:36:29 GMT -5
wilscase: The genes involved are Bmax and bl. I have observed that Bmax is incompletely dominant to wild type (green). I have read that bl is incompletely recessive to Bl(wild type). I'm curious if anyone else has observed the behavior of Bmax in a grey/blue type
Oct 18, 2022 21:38:28 GMT -5
wilscase: It appears that bl and Bmax are interacting to produce different shades of salmon and pink.

wilscase: I'm also interested in any other color genetics, especially the relationships between B and L genes. In the right background these genes can dramatically increase Carotenoids (vitamin A)
