Characteristics of Red Maple Progenies from Different Geographic Areas1


Variation analysis showed significant variation among red maple (Acer rubrum L.) progenies grown from seed collected throughout the species’ natural range with respect to height, diameter, autumn color, winter injury, earliness of flusing and cessation of growth. Northern progenies showed slowest growth, most reddish autumn color, earliest flushing and budset, and least winter injury. Most traits were significantly correlated with several geographic and climatic variables, and genetic and phenotypic correlations among traits indicated that multiple-trait selection could be effective.
