Fifth Year Results of a Slash Pine Polycross Progeny Test in Georgia

In 1954, seed orchards of selected slash pine ( Pinus elliottii Engelm.) and loblolly pine ( P. taeda L.) were established in Georgia by the Georgia Forestry Commission to develop and produce superior seed. Progeny testing of the selected trees was initiated as soon as pollen production and female flowering were sufficiently abundant in the orchards to permit controlled pollinations. This paper reviews the fifth-year results of the first slash pine progeny test to be outplanted. This planting tests 35 of 179 slash pine clones in phase' I of the progeny testing program used by the Georgia Forestry Commission to develop its seed orchards.
