Gary Ibsen's Gold versus KBX!

I grew some Gary Ibsen's Gold from seed last October to experiment on during the winter. I wanted to see what the overall effects of various types of root damage would be on the seedlings. My intent was to toss the plants when I was through trying some things. The plants were so vigorous and healthy, I decided to plant and grow a couple of them in the spring. I did have to cut and regrow from cuttings a couple of times because they grew so fast.

This spring, I planted them in the soil beside some KBX seedlings. The plants grew and looked identical with PL leaves. They bloomed and set fruit early, identically. We had a few nights in the thirties while they were blooming early resulting in some deformed, knobby, fruit on both plants. Even the deformed fruit on both varieties is identical. Neither variety set much fruit while other varieties around them like Pineapple and Brandywine Yellow are heavy producers within a few feet of them in the same bed.

I'm waiting for both varieties to ripen some fruit, but I am beginning to believe Gary Ibsen's Gold and KBX are the same cultivar.

I don't suppose it matters, but I only need to grow one variety in the future if they are the same.
