Yield of advanced lines of peanut under rainfed conditions in northeast Brazil

摘要

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).

Individual and joint variance analysis were carried out and Tu
