Cucumber Cross Pollination

Hi All
I have planted some Burpless Tasty all female cucumbers in the greenhouse, if I grow a different variety that is not all female will the Burless Tasty be pollinated by the other variety and then go bitter??
I would like to try a different variety without the risk of spoiling the usual type.

Thanks

Dave :confused:

 

Don't know DG. I have only grown those with both flowers on, cutting out the male if I remember rightly. Unfortunately got no germination this year with cucumber. Had good success with crystal apple variety a couplke of years ago. Must get some fresh seed!!
