The breeding programs focused on semiarid environments significantly invest on selection of early-mature genotypes with the ability to maintain yield at reasonable levels, when drought sets in. The fastigiata peanut genotypes have broad physiological adaptation to environments prone to drought, while subsp. hypogaea are less tolerant, but are excellent to pod yield. The combination of these intraspecific materials via hybridization often provides robust descendants to breeding works focusing on yield and drought tolerance. In this work we adopted a clustering method to assist in the selection procedures of intraspecific peanut elite lines, based on molecular tools and physiological, biochemical and agronomic traits. Initially, fourteen intraspecific top... |

Essential oils of seven species were investigated in order to control peanut plants against white mold (Sclerotium rolfsii Sacc.). The assays were carried out by in vitro and in vivo assays. At first, fungitoxicity and suppression of oxalic acid diffusion (SOAD) bioassays were performed in order to evaluate the mycelial growth of fungus. Then, validation assays were carried out in greenhouse, involving inoculation of fungus in the seeds and further plant treatments with essential oil. Four isolates of S. rolfsii were tested in different oil concentrations. Cymbopogon martinii oil at 300 ppm inhibited the mycelia growth of S. rolfsii in 55% and also the number of sclerotia. In validation assay, we found that a single dose of C. martinii oil at 400 ppm... |
