The objectives of this study were to determine if there are: (1) genetic differences in growth traits among provenances, (2) any trends of significances for locating the most suitable provenances, and (3) any geenetic-environment interaction. Additional objectives were to determiee (4) future uses of the trials, (5) improvements of the experimentalpprocedures, and (6>) future direction of the experimentation aiming a the genetic improvement of these pines. Thirty-five seedlots of loblolly pine and 20 seedlots of slash pine were tested in two series. Redommized and replicated trials were established in four locations. Mortaiity was higher in Series 1 for both species due to long-distance transportation of bare root seedlings. There were very importandiffences in loblolly pine growth rate due provenance in both series. On seedlots from Livingston Parish was consistently among a leader at all test locations. Other seedlots from Florida, Mississippi, South Carolina, and one Braszlian seedlot were also fast growing. Genotype-environment interaction were strong in Series 1 and smaller in Series 2. Ageneral trend of coastal seedlots to growth faster than ones was observed in both series. The most higly recommended area seed collection for planting in Brazilis the coastal region stretching 120 kilometers from the coast of the Gulf of Mexico and the Atlantic Ocean is seven southern states. The consistent superiority of Livingston Parish indicates that Brazilian growers can obtain immediate improvement (...)
