As far as I know, El Dorado was developed in Yakima and does not have a NM hop background. One that was in development from NM stock was simply called "LR" when I got a sample of it, I don't know if it has taken on another name since. I know it is not the same as El Dorado, because I was also given some of those.
If you were at the NHC in Seattle and went to Stan Hieronymus's talk on hop varieties, two of the single hop beers were made with those varieties. The other two were Meridian and Mosaic.
