The use of molecular markers to study genetic diversity represents a breakthrough in this area, because of the increase in polymorphism levels and phenotypic neutrality. Codominant markers, such as microsatellites (SSR), are sensitive enough to distinguish the heterozygotes in genetic studies. Despite this advantage, there are some studies that ignore this feature and work with encoded data because of the simplicity of the evaluation, existence of polyploids and need for the combined analysis of different types of molecular markers. Thus, our study aims to investigate the consequences of these encodings on simulated and real data. In addition, we suggest an alternative analysis for genetic evaluations using different molecular markers. For the simulated data, we proposed the following two scenarios: the first uses SNP markers, and the second SSR markers. For real data, we used the SSR genotyping data from Coffea canephora accessions maintained in the Embrapa Germplasm Collection. The genetic diversity was studied using cluster analysis, the dissimilarity index, and the Bayesian approach implemented in the STRUCTURE software. For the simulated data, we observed a loss of genetic information to the encoded data in both scenarios. The same result was observed in the coffee studies. This loss of information was discussed in the context of a plantbreeding program, and the consequences were weighted to germplasm evaluations and the selection of parents for hybridization. In the studies that involved different types of markers, an alternative to the combined analysis is discussed, where the informativeness, coverage and quality of markers are weighted in the genetic diversity studies.

The objective of this paper was to evaluate the influence of indigenous and inoculated rhizobia and ammonium sulfate fertilizer on growth and mineral composition of the herbaceous legumes, Calopo (Calopogonium mucunoides), Ea Ea (Desmodium heterocarpon subsp. ovalifolium) and Kudzu (Pueraria phaseoloides), which are commonly used as forage plants and cover crops in Brazil. The treatments did not exhibit differences for total biomass of nodules. Lime application along with basic fertilization (without N) permitted nodulation and full growth and development of forages with native rhizobia.
O objetivo do presente estudo foi avaliar a influência de rizóbios nativos e inoculados, e o uso do fertilizante sulfato de amônio sobre o crescimento e a composição mineral de leguminosas herbáceas, calopogônio (Calopogonium mucunoides), desmódio (Desmodium heterocarpon subsp. ovalifolium) e puerária (Pueraria phaseoloides), que são utilizadas como forrageiras e plantas de cobertura no Brasil. Os teores de nutrientes foram adequados em todas as três espécies e não foram observadas diferenças. Rizóbios nativos foram tão eficazes quanto os rizóbios inoculados no fornecimento de N para as plantas. A biomassa total de nódulos não diferiu entre os tratamentos. A calagem, juntamente com adubação de base (sem N) permitiu a nodulação e crescimento integral e desenvolvimento de forrageiras com rizóbios nativos. |
