A Study of Racial Variation in Loblolly Pine in Georgia, Tenth-Year Results

The Georgia Loblolly Pine Racial Variation Study was designed to complement the Southwide Pine Seed Source study by testing samples of loblolly pine seed, from collections made in all provinces of Georgia, in plantations established throughout the state. It has performed this function in a most admirable fashion. In general, the results do not conflict in any way with those recently reported on the tenth-year results of the loblolly phase of the Southwide Pine Seed Sour ce Study (Wells and Wakeley, 1966). Basically, the data obtained in the Georgia study indicate that the variation in the growth of loblolly pine from different parts of the state is of sufficient magnitude that it will require consideration in seed procurement and planting plans. It is an important factor in the seed orchard program of the Georgia Forestry Commission.
