The excellent holding ability of K326 is based on the ability of this cultivar to maintain its weight after it reaches the fully ripe stage. Progeny with K326 in their pedigree tend to have good to excellent holding ability, e.g. K346, K358, NC71 and NC72. Progeny from cultivars with only fair holding ability like NC2326 also tend to have the same holding ability, e.g. NC37NF. Thus holding ability appears to be a heritable trait.
