Variety traits
Juglans regia L.
The ability of a walnut tree to produce viable fruit when pollinated by its own pollen. This trait is key to overcoming dichogamy and ensuring stable yields under isolated conditions.
In the reference 46 varieties crop Persian walnut, where this is mentioned in the description.
In walnuts, self-fertility is assessed as a qualitative genotype characteristic by observing the fruit set of isolated individuals growing at a significant distance from other trees. There are no standardized quantitative indicators or scoring scales for evaluating this trait in breeding programs.
A biological characteristic of the walnut is dichogamy, where the flowering periods of male and female inflorescences on the same tree often do not coincide. Self-fertile forms are highly valued in breeding, as they reduce yield dependency on the presence of pollinator trees and weather conditions that hinder pollen transfer.
