Excerpt from Growth of Outstanding Nursery Seedlings of Pinus Elliottii Engelm. And Pinus Taeda L These selected seedlings are only the first step in isolating material. The test plantations established with them will be observed and further selections made for combinations of desirable traits (fig. Our data indicate a Wide range of fusiform rust infection, ranging from none to more than 15 cankers per tree. It would be difficult to explain these differences in terms of escapes or other chance phenomena. Some of the most vigorous trees are free of rust, though more than three -fourths of the total number of trees are rust infected. The rust -free trees are apparently randomly scattered throughout the plantations. The form of the faster growing slash pines is about the equivalent of that in' slower growing material and indicates that crown form is probably not highly correlated with vigor. Form estimates were not made in loblolly pine because of the confounding of tip moth damage. Nursery selection appears to offer good potential as a means of isolat ing superior individuals for breeding purposes. If the performance of the selected seedlings continues as it has the first 4 years, the degree of success will be high enough to justify the expenditure of considerable effort to isolate material in the nurseries. Thousands of seedlings can be screened rapidly and selection criteria can be adjusted to obtain populations of the desired Size. However, it will probably be feasible to select only for vigor. Selection for characters, such as stem form, wood quality, and pest resistance will prob ably have to be delayed until the trees are well established in the field. The relative efficiency of selection for several characters simultaneously may be less here than by other methods.
