Twenty one provenances of Grevillea robusta Cunn were tested at Nova Esperança and Quedas do Iguaçu, Paraná state and Anhembi, São Paulo state, Brazil. With the aim of comparing the performance of the original provenances with the comercial provenance collected in Maringa, Paraná state included as a control. Provenance trials were installed in a randomized block design with rectangular plots, each one with six plants spaced 3 m x 3 m, with 15 replications. Five among the ten best provenances at Anhembi presented better growth at Quedas do Iguaçu and Nova Esperança (Duck Creek, Fine Flower, Rappville, Bottle Creek and Mc Pherson’s Creek). Different environments did not interfere significantly in the average growth among different provenances indicating that... |

P. elliotii var. elliottii is the second most planted fast growing tree species in Brazilian subtropics for wood and resin production. The objective of this work was to predict genetic values of fast growing individual trees. A trial was established in a randomized complete blocks design involving 76 treatments, 75 open pollinated progenies from a clonal seed orchard and a commercial progeny as control, in a 3 m x 3 m spacing. Total heights of all individuals were measured at 1, 2, and 3 years old and also stem diameter at 1.3 m height- dbh at 3 years old. Deviance analysis was performed by using Selegen-REML/BLUP software and genetic parameters were estimated. Significant variation was detected among progenies. Estimates of narrow-sense individual... |
