Question about hybrid vegetables
  • Lol no I only doing a little breeding as a hobby now (Halloween pumpkins).

    Last count I had 14 different suppliers from local to internationals.

    I have dealerships, distributorships, as well as open market suppliers. I do both wholesale and retail.

    Basically, I don't go fishing enough.

  • Question about hybrid vegetables
  • Just about anything except vegetable seeds.

    Field corn, alfalfa, cereals, hay grasses, forage crops, turfgrass, covercrops, native grasses, flower seed etc. I never quite know what I will be moving next.

  • Question about hybrid vegetables
  • I got out of vegetable seeds about a decade ago. My tendency to make the brown-nosers look absolutely stupid became a liability once I hit upper management. Imagine a plant breeder with a talent for computers, logistics, marketing and sales. I asked all the "wrong" questions.

    Currently running my own seed dealership/research activities for row crops.

  • Question about hybrid vegetables
  • You've underestimated it by a bit. It takes 2-3 generations to increase the inbred seed quantities after selfing. So figure 20 years. Plus the female line takes 5 generations to create so another 10 years (onion hybrid seed production requires 3 lines: Male, maintainer & female - the female has cytoplasmic male sterility). All together it used to take 30 years to create a new female line.

    Today onions are self-pollinated traditionally for 2 generations, then double-haploids are produced. It takes another 2-3 generations to create the female line with marker-assisted back-crossing. It takes 2-3 generations to create enough parent seed to produce commercial hybrids. So say 12-16 years now for a female line. 10 years for the male and maintainer.

  • Question about hybrid vegetables
  • Seeds of many species, when stored correctly, can still germinate for decades. I have used seed that was 30+ years old several times before.

    Breeders produce inbred parental lines by self-pollinating for 5-8 generations (or double-haploid creation).

    They then do a small initial seed increase by bulking a generation. Bulking refers to combining the seeds from several plants (I used nethouse with 24 cantaloupe plants and a small young queen honeybee hive inside to produce 0.5-1kg of seed).

    This is called basic or breeder seed. This lot is tested for genetic uniformity and seedborne diseases. It's also used for small hybrid seed productions to test out the inbred.

    Breeder seed is increased again and bulked to make foundation seed (around 50kg for cantaloupes) This is used to make the first commercial production of the hybrid. It is then increased yet again to produce stock seed (500kg)

    Stock seed is what the commercial hybrid is produced from for the rest of its life. Foundation seed is used to produce more stock seed as needed.

    The breeder seed and foundation seed are stored carefully to prolong it's life. The stock seed is in the general warehouse with the hybrid seed.

    As long as they maintain quality control during the inbred increase process, the resulting hybrid will always be essentially the same.

  • Do you ever have a tomato plant that dies for seemingly no reason?
  • At first I thought it was one of the "wilts". These are soil-borne pathogens that attack the plants roots. The causitive organism could be verticillium, fusarium, or phytophera. In small plants pythium or rhyzoctonia can kill them. There is also bacterial wilt that causes the rapid decline of the plants.

    Then I zoomed in and took a closer look at the plant. I suspect it's nitrogen deficiency. It could be caused by over-watering (denitrification and leaching nitrate out of the soil profile). However I suspect you didn't have enough to start with.

    The tomato tone looks to be a 3-4-6 fertilizer. To put it simply, it's a stupid fertilizer blend. Plants need nutrients with a ratio of around 3:1:2. So you need 3x+ more nitrogen in that blend.

    Once the plant sets fruit, it starts to dedicate nitrogen into the fruit/seeds. In a shortage situation it moves them from the lower leaves (they turn yellow and die).

  • Powdery mildew on squash leaves?
  • It's referred to as leaf silvering. It's a genetically controlled trait common in the Cucurbita genus. That being said those are a bit extreme.

    Take a look at the underside of the leaves. Silverleaf whiteflies could also be the cause.

  • Huge tomato and bean flowers
  • The beans have some sunscald on the leaves due to the change in temperature. It's cosmetic and will not cause any harm.

    FYI your tomatoes are also showing the heat stress with physiological leaf roll. It's also cosmetic.

  • You never got stuck in formatting hell on word-perfect apparently.

    It was pretty easy in creating new original documents.

    Editing existing documents was an absolute nightmare. The list was extremely long of random shit that would happen we you deleted some text.

  • Russian boat is hit by an FPV drone in the night.
  • On the flip side:

    Water masks their heat signature. So getting into the water while the boat is still moving and swimming away from the burning boat may be a good option to hide. They need to stay underwater for as long as possible though.

    Mount the 20mm cannons, add in some modernized targeting software able to detect and hit the small drones. Stage them on small runways all around the country. You also have a ton of very experienced pilots around the world who are by definition, fucking crazy.

  • Windows 11 is now automatically enabling OneDrive folder backup without asking permission
  • They made it the default option for businesses that routinely buy computers with less local storage than their users need. Pretty much every company I have worked for.

    They then pushed it out hard into the consumer market when SSD came out and the average storage space on lower end models dropped by 75%.

    I see why they did it, how they did it was in usual Microsoft fashion, idiotic.

    It's sort of their pattern.

    1. Introduce new changes.

    2. Screw it up royalty.

    3. Fix the features that are salvageable and revert most of the remaining except: Double down on the shitty ones that they think will make them more money.

    4. Rinse and Repeat

  • I pollinated cherry tomatoes on my balcony with a cotton swab for the first time and it's working well!
  • FYI Tomato flowers are cleistogamous and are 95%+ self-pollinating. So pollen on tomato flowers doesn't actually need to be transfered between flowers. The flowers just need to be shaken up a bit to get the pollen to drop from the anther to the pistil.

    So take something that vibrates like a electric toothbrush, massager, or other personal devices (wink, wink) and shake the hell out of the flowers.

  • Dell said return to the office or else—nearly half of workers chose “or else” - Workers stayed remote even when told they could no longer be promoted.
  • It leaves dell with employees who do their job and have a life outside of work. They will put their hours in but not much more. They do not recommend change or new ways of getting things done, because they don't care. They will do the minimum and punch the clock for years until they find another better paying job.

  • [BUG] When scrolling a long list eventually the app freezes and crashes.

    Happens on both my Nokia G50 and S23. Scrolling past a hundred plus post it becomes sluggish then crashes the app.

    Perhaps something to do with memory management?
