Genotypic Variation in White Ash

In the past few years attention has been increasingly focused on the importance of seed source in the establishment of forest plantations. The choice of the proper seed demands a knowledge of the genetic variability of the species to be planted. For most of our American trees, especially the hardwoods, these data are lacking. The present study was undertaken to supply basic information on an important group of deciduous trees that might serve as a background for sound planting practice and for future breeding work.
