@"Figology"#21 . I (liked) your post to show my extreme respect for your opinion. Growing all three variety side by side certainly gives great veracity to your observations, and opinion.
Still I believe there is some room for a UCR designated variety named long yellow neck. This controversy certainly goes back farther than 2018. Here is a copy of a post by Romeo dating to 2018 when a first-year moderator of another online forum was also growing side by side comparisons of two of these three varieties. I wonder about long yellow neck due to a UCR varieties comparison that points out subtle, but real differences in the structure of long yellow neck compared to Yellow long neck, golden Riverside, and golden rainbow. Harvey also says his variety is different than Ben's. I am quoting comments that are 6 years old from another online platform.
I invite any mod to delete this post, because it would take all day quoting controversial post from 6 years or more that I do not have time today to accurately quote. It's not the difference i in leaves fruit color or flavor that leads me to suggest that there may be a (long yellow neck UCR variety) that is different then yellow long neck, golden riverside, and golden rainbow. What leads me to say this, old side by side video comparisons that show definite differences in the physical structure of the neck of the fruit of long yellow neck UCR variety. Physical differences in the neck might not be attributable to caprification, or climate differences. Long yellow neck is rarely described online. There could be more confusion on Long yellow neck. Then other similar, or synonyms of yellow long neck. Here's a copy paste quote from another platform dated 2018. As I said before please delete this if it's going to cause trouble. This is dated from 2018.
"My BGR came from a very reputable fig collector this past spring, long before it was on anyone's radar. He received his directly from Ben. When mine began to ripen figs, I verified the fig shape, color, texture, and fig leaf shape with Ben's post as well as other posts."
"I also have a 5 yr UCR 278-128, direct from UCR, which was originally nicknamed Golden Riverside. I studied the leaves, tasted the fig.
My conclusion... these are two different varieties, with completely different leaves, figs, and taste profiles."
