Eleven upright and runner peanut advanced lines were conducted conditions in four states located in the northeast region aiming to evaluate their pod and seed yield. Assays were carried out in the agricultural year 2005/2007 in the states of Pernambuco (Araripina and Parnamirim), Sergipe (Lagarto), Bahia (Cruz das Almas and Caetité) and Paraíba (Campina Grande and Itabaiana). A completely randomized block experimental design with five replications was used with 13 treatments (8 upright and 5 runner genotypes). The analyzed variables were pod and seed yields. Individual and joint variance analysis were carried out and Tukey (p < 0.05) test was used to compare treatments. The BR 1 cultivar was adopted as a control. The highest pod and seed yields were obtained by LN-1B, with 2,450 and 1,665 kg ha-1, respectively, overcoming the mean of upright lines in 22 and 21%, and of the BR 1 cv. in 11 and 10%. As to runner lines, the pod and seed yields were not satisfactory under the conditions, however, LI-3, LI-5 and LI-1 overcame the group, with 1,722 and 1,154 kg ha-1, corresponding to 9.8 and 10% over general mean, respectively.
