Question

Do hybrid plants have shorter lifespans than non-hybrid plants? What is another word for non-hybrid?

Answer 1

open pollinated is another term for non hybrid.

the above person is correct about lifespan though.

If you are looking to understand the differences, or why one might be better -

Open-pollinated vegetable varieties reproduce themselves in one of two ways: cross-pollination between two plants (via wind, insects or water) or self-pollination (between male and female flower parts contained within the same flower or separate flowers on the same plant).

So long as plants of an OP variety are kept isolated from different plants with which they can cross, they will produce seed that will come "true to type." In other words, the plants in the following generation will resemble the parent plants.  This means that not only are these plants fertile, but they will also make babies that will resemble the parent line (that is "true to type")  It is stable.  You can breed plants, crossing two (or more) different parent lines- the result of the first year crossing would be a hybrid, if you keep breeding them, rouging out plants with undesirable or off type characteristics eventually after quite a few growing seasons the population would stabilize, becoming open pollinated.

A "hybrid" vegetable seed results from the cross or mating between two different varieties or "parents" of the same plant species.  Generally it is the FIRST year of a cross between to different parent lines.  Seeds from the fruit of this hybrid, may be sterile.  If it is not, than the resulting plants may have all different characteristics from either one of it's parents.

This puts the power into the hands of seed companies, rather than farmers.  Farmers need to go back to the companies/breeders year after year to purchase hybrid seeds/plants.

With open pollinated seeds (as long as you pay attention to isolation distances if growing more than one variety of a species) you can save your own seed, and be saving money every year, as well as the benefit of being that much more self sufficient.

this might have been more info than you wanted, but seed saving is a subject that is close to my heart.

Here's a good article describing the differences of OP's and F1 Hybrids

Answer 2

There's no generalized answer to your question.  It depends on the species being hybridized and their environmental conditions.

Another term for non-hybrid is purebred.
