Aloe 'Coral Edge' x A. juvenna hybrid

Post Number:#1  Postby Marlon Machado » Wed Feb 14, 2018 4:25 pm

The plant on the left is Aloe 'Coral Edge'. In the back is an Aloe juvenna. Between the two is a hybrid with 'Coral Edge' as the seed and juvenna as the pollen parents. Quite interesting texture in this particular seedling. Bred by Constantino Gastaldi from Brazil.

Very interesting, and great photo showing the story of the two parents and that offspring. I find it also interesting that the hybrid seems to have had more influence in that progeny than the species plant.

Yes Tom, the seedling has a number of unexpected characteristics. The cream-white ridges on the leaves for example, and a stronger, more continuous red edge than the one in 'Coral Fire'.

Think for instance of Aloe 'Doran Black'. Its parentage is given as "a complex cross of aloe species, including A. albiflora, A. bakeri, A. descoingsii and A. juvenna". In 'Doran Black' you can see the influence of descoingsii in the short, deltoid leaves, but little of the other parents. None of the species feature the dense, raised white tubercles or ridges that 'Doran Black' has. Aloe bakeri has smooth leaves, albiflora has leaves rough but that is due to the raised epidermal cells, and descoingsii has smooth leaves. I think it was the influence of juvenna that gave the ridges to A. 'Doran Black'. You can see how the hybrid in the picture above look a bit 'Doran Black'-ish, again an influence from juvenna me thinks.

Yes, I was thinking about that too. Regarding the ridges though, I understand that 'Coral Edge' is a KG hybrid, and so many of his hybrids feature just such raised ridges. I would not discount the possibility that although CE doesn't itself exhibit that particular characteristic by phenotype, it's does seem likely to me that given it's origin, it could well contain the possibility for such in it's genotype. I'm also wondering how the rest of the seedlings turned out - what sort of variability was present, and if the one featured by the cross is a select individual of more outstanding perceived qualities than the average.
No matter what, all very interesting and thought provoking.

EDIT - I was just looking at the entry for this plant on Dave's Garden - this example pictured shows a plant that does actually exhibit some of those very raised ridges, supporting the idea that the cultivar has in it's genetics that characteristic, even if the parent plant itself didn't feature that quality so much...
