I'm interested in your quest for the "perfect cucumber". Tell me more.
Well, I guess simply stated, right now I'm looking for an excellent burpless cucumber that also shines when pickled and canned. I like all kinds of cucumbers, but I have a brother whose stomach can't tolerate "regular" cucumbers. So, over the years, I've been on the hunt for that "perfect" burpless cucumber. I'm hoping one, or both, of the burpless ones I'm growing this year will be THE ONE, lol. Back in 2007, Burpee sold a cucumber called "Burpless". That was its name. Back then, I think that was the ONLY burpless cucumber they sold. I guess it was before burpless became a thing. It was an excellent cucumber, and my brother loved it. Now they sell several burpless cucumbers, just not one named Burpless. So, I'm on the hunt, lol.
Now, from a slicer point of view, I have two favorites that I grow regularly. The first is
Marketmore 76, which it sounds like you're familiar with. I'm not sure if it's a hybrid, but I guess it could be. It was developed in the 60's from a cucumber called "Marketmore", and released in the early 70's. I think it's been "stabilized" since then. And, I agree with your flavor assessment - rather "mild", not a strong cucumber taste, but still acceptable. I think Its strengths are its productivity and reliability. Nice cucumber, overall.
My other favorite slicer that tops my list is
Straight Eight. Excellent flavor, very productive, as well as reliable. Probably the one I compare all others against. This is the one to beat, for me. As a side note, there was a cucumber released some time back called Straight Nine. It was supposed to be all things Straight Eight, only more resistance to disease and whatnot. I found this cuke to be LACKING in all the areas that make Straight Eight so good, at least to me. Therefore, I didn't give a flip about all its disease resistance.
And then there's picklers. Maybe we'll save that one for another day, lol. I'm sure this is much more than you wanted to know, haha.
