In many crops the seeds planted are hybrids, which don't breed true either. That non-issue has been there since before you, and possibly your parents, were born.
What keeps the (gasp! shudder!) corporate ownership of these things from sinking us into a dystopian hellscape? Competition. You don't like one kind of hybrid? Buy a different kind. The seed makers compete fiercely for farmers' business. The same is true of GMOs.
That doesn't mean that they are a good idea.

And in many other crops Monsanto sues the hell out of farmers who replant the non-hybrid seeds.
> Competition.
Are there actually seed makers that would not sue their customers for replanting?
Monsanto had a contract with farmers to not replant the seeds. The farmers were free to not use the seeds and not sign the contract. Enforcement of contractual obligations is a vital glue that holds society together; why are you against it in this case?
In all this, I detect entitled selfishness on your part: you want (or you think the farmers should have) the benefits of these improvements, without having to respect the mechanisms that allow the improvements to be made.
As for how patents (and other intellectual property rights) correlate with innovation, that is debated. Here's a random article I picked out of a web search: https://www.knowablemagazine.org/article/society/2018/do-pat...
For whatever it's worth, the research we're discussing here is being done not at a for-profit seed maker but at a non-profit university. Universities are good at getting government grants, for example, for innovations that would benefit everyone, like improved seeds.
As for patents: while patents in general have dubious applications, plant patents in particular are not dubious at all. Patents are absolutely essential here, because the cost of manufacturing is extremely low (just grow the plant!) If plants that breed true could not be patented then developing them would be worthless. The cost of development could not be recouped after the first sale.
Also, the whole "plant patents date back to 1930" line is literally out of Monsanto's talking points.
Yes, the 1930s plant patents are a bit different. But they are still corporations owning IP in plants. It didn't end the world then, it's nothing but a source of faux outrage now.
The original one is still there for all to use.
