  • Description in 1958 Gleckler Seed Catalog catalog:
"CUYANO - New Smooth Marman - A new strain of Marman developed by Prof. Abelardo Piovano at the National University of Argentina. An outstanding improvement over the original strain. Maturity a few days earlier, vine growth the same but more resistant to fungus diseases. Fruit quality is greatly improved, much smoother and solid. Interior is fleshy without cavities or puffiness. Size is somewhat larger in the early clusters, which is the important part of fruit setting for early market. In both vine and fruit this new strain of Marman called Cuyano is a great improvement over the original strain."
