Do cucs and summer squash and if they do does it effect this years crop or only next year's seeds?

'A common misconception is that squash, melons, and cucumbers will cross-pollinate.This is not true; the female flowers of each can be fertilized only by pollen from that same species. Varieties within each species, however, will cross-pollinate.'

My personal opinion, is that a lot of these "crossbreeding" horror stories circulated from poor seed quality years ago.

It used to be that anyone could (and did) sell seeds, with little no controls/certifications. Many times the original growers didn't take the time to properly "fix" (breed true for 8 sucessive generations) hybrids and simply rushed stuff out to market as soon as they got a trait they liked.

Additionally, improvements and cost-reductions in commercial hydroponic cloning have made it possible to bring reliable "fixed" varieties to market much sooner, without all the genetic variation.

Without going into a lot of gory detail, the first generation offspring (F1) usually generates the best/strongest traits of a plant, so folks would collect the seed from that generation, often without "fixing" the variety/trait (can take 3-6 years, or longer, depending on the plant). The problem is, the next generation (F2) is typically the generation that produces the most variety in traits ..... so folk got a big surprise.

Nowadays, with all the cerification of seed & seed providers, I think your chances of experiencing "crossbreeing-surprise" are much lower (unless you collect your seed yourself) .... both from the quality of the seed stock and the improvements in technique.

But again ...just my $.02
