  In order to generate information relevant to the Mato Grosso do Sul (MS), the aim was analyze the occurrence of wet and drought periods through the SPI using Standardized Precipitation Index (SPI) in this Brazilian State. Rainfall data of 29 stations (sites) of MS were obtained of the National Water Agency Database collected from 1983-2013. At each site and year, the rainfall daily data were added up to obtain the monthly rainfall (mm month-1), of each month of the year. Thus, were formed 348 time series (12 months×29 sites), that it were used to calculate the SPI in annual scale. The fit was found Normal distribution of 384 time series of monthly rainfall using the Kolmogorov-Smirnov test. The SPI is able to identify the drought and wet periods, when the occurrence of ENOS events, regardless of categorization, in Mato Grosso do Sul State, Brazil. The analysis of the relative frequencies shows that the moderately drought and wet categories stands out about the other categories of SPI. The moderately drought category occurs in episodes of El Niño strong and moderate and moderately wet category in episodes of La Niña strong and weak.

  In order to evaluate the agronomic performance and estimate the genetic variability of 24 common bean genotypes grown in the Savanna-Pantanal ecotone and see, which characters can be used for selection of superior genotypes. Treatments consisted of 24 common bean genotypes (CNFC 10429, CNFC 10408, CNFC 10467, CNFC 10470, CNFC 10762, CNFP 10104, CNFP 10793, CNFP 10794, BJ4, CNFRJ 10556, VR3 VC3 e VC6, IAPAR 81, BRS Campeiro, BRS 7762 Supremo, BRS Esplendor, BRS Valente, BRS Pitanga, BRS Radiante, BRS Requinte, BRS Pontal, BRS 9435 Cometa e BRS Estilo). The following traits were evaluated: Early flowering, early maturity, height of the first pod, number of pods per plant, number of grains per pod, weight of 100 grains and grain yield. The following parameters were estimated: environmental, phenotypic and genotypic variances, experimental and genotypic coefficient of variation, genotypic coefficient of determination, b quotient, environmental, phenotypic and genetic correlations. The CNFP 10794 genotype had the best agronomic performance in the Savanna-Pantanal ecotone region. The population presents genetic variability and potential for selection of all traits. Based on genetic parameters estimates, the characters number of grains per pod and weight of hundred grains can be used in direct selection for more productive genotypes.

  This work aimed to identify the most effective method to estimate the coefficient of repeatability in genotypes of U. brizantha and predict the minimum number of measurements required for some qualitative traits. It were evaluated 9 genotypes in a randomized block design with two replications in the rainy season and drought in 2000. It were evaluated the following qualitative traits: volume of gas, in mL, packed in fast and slow fraction, crude protein; neutral detergent fiber, acid detergent fiber, cellulose, lignin sulfuric acid, silica and in vitro digestibility of organic matter. The repeatability coefficient (r) was estimated considering different strategies: Analysis of variance, principal component analysis based on the correlation matrix (CPCOR), principal components analysis based on the matrix of phenotypic variance and covariance and structural analysis based on the correlation matrix. The CPCOR method, provided more accurate estimates of r and the number of measurements required for the qualitative traits assessed due to the cyclical behavior of genotypes of U. brizantha. The traits neutral detergent fiber, cellulose and silica require two measurements, while the remaining characters require four measurements to predict the actual value of genotypes of U. brizantha with a minimum accuracy of 80%, by CPCOR method.
