The agronomic performance of seven accessios of Arachis pintoi was evaluated between Jauary 1994 and November 1996, on a humic gley Inceptisol. The trial was conducted at the Brasilia Faculty of Agriculture (1500 mm rainfall; 1000 m.a.s.l.; 15o 35' S and 47o 42'W), Planaltina, DF, Brazil. Soil was prepared mechanically for planting, but no fertilizers were applied, nor herbicides for weed control. The treatments consisted of seven accession of A. pintoi that were pre selected at the Cerrados Agricultural Research Center (CPAC) of EMBRAPA. These accessions belonged to a collection of 80 accessions, obtained during expeditons conducted under the coordination of the National Center of Genetic Resources and Biotechnology (CENARGEN), also of EMBRAPA. The germplasm was planted in January 1994 and evaluated until November 1996. Vegetative material was used as planting material for both the legume and the grass Paspalum maritimum BRA-000078. After 60 days of rooting, the A. pintoi plantlets were transplanted at distances of 0.7 m between rows and 0.5 m between plants in 20-m2 plots. The grass was planted between the rows of legume. A completely randomized design was used, with three replications per treatment. The associations of the grass with A. pintoi accessions BRA-013251, BRA-015121, BRA-031135, and BRA-031143 were relatively stable over time. The accessions A. pintoi BRA-030368 and BRA-031542 diminished in the asscociation: after 2 years of cuttings and consecutive grazings, they represented barely 5% of the botanical composition. At the end of the second year, A. pintoi BRA-031828 was the only accession to comprise 60% of the associated pasture, showing good vigor and excellent plant health. Paspalum maritimum BRA-000078 showed high branching ability and stem growth, reaching an average lenght of 703 +- 308 cm per plant and a daily growth rate of 6.8 +- 3.0 cm, between 0 and 104 days after planting. These results highlight the potential of this grass for use in degraded areas; for example, to control erosion on slopes and combat weeds.

With the aim of finding quantitative phenotypic traits that can be used to discriminate the levels of resistance/susceptibility to Babesia bovis, we estimated the repeatability and correlation between the level of infection, determined by the number of copies of a fragment of the gene that encodes cytochrome B (NC mt-cyB) of B. bovis, and the levels of the anti-B. bovis antibodies, in blood samples collected from 51 Angus cattle on two different occasions. Samples with the anticoagulant EDTA were used for DNA extraction and without anticoagulant for separation of the blood serum. The quantification of the NC mt-cyB of B. bovis was carried out by the quantitative PCR technique (qPCR), while the anti-B. bovis IgG antibody titers (S/P) were quantified by the ELISA method. The NC and S/P data were log10-transformed to improve the approximation to the normal distribution and were analyzed using mixed models. The correlations between NC mt-cyB and S/P were estimated, as well as the repeatability values for each trait. The results obtainedshowedthehighsensitivity ofthe techniques, with100%ofthe animals beingpositive for B. bovis, detected by both the serological and molecular tests. The correlations estimated between NC and S/P were low, 0.10 and 0.12, in the first and second collection, respectively. The repeatability estimated for NC was 0.06, whereas for the S/P it was 0.42. The low correlations between S/P and NC in the two collections demonstrated that the variation in the NC value is independent of the level of antibodies. This results indicated that animals with a higher levels of antibodies against B. bovis in the first collection continued to have a higher levels in the second one. However, the very low values for the repeatability value of NC, and for the correlations between S/P and NC, demonstrates that neither NC or S/P could be used to discriminate animals for resistance/susceptibility to B. bovis.
