Os requerimentos de drenagem, parametros e correspondentes relacoes economicas sao estudadas para os latossolos do P.I. Bebedouro. A area estudada ocupada parte dos solos principalmente da unidade 37 BB, representativos de aproximadamente 30% da area do Perimetro. Os estudos sao realizados num sistema de cinco linhas de drenos subterraneos paralelos, instaladas no lote 74 a 1,5 m de profundidade com m de espacamento. A recuperacao de 1,64 ha de videira gravemente afetada por excessos de umidade, devido as chuvas do ultimo inverno e a sua produtividade, assim como as variacoes da profundidade do lencol e das condicoes de umidade do perfil sao avaliadas para definir parametros de drenagem para os latossolos do Perimetro. Os custos dos trabalhos de drenagem foramde 101,04 ORTN/ha que significam menos de 15% dos custos de implantacao da videira. |

Abstract: Single nucleotide polymorphism (SNP) markers are used to study population structure and conservation genetics, which permits assessing similarities regarding the linkage disequilibrium and information about the relationship among individuals. To investigate the population genomic structure of 300 females and 25 males from a commercial maternal pig line we analyzed linkage disequilibrium extent, inbreeding coefficients using genomic and conventional pedigree data, and population stratification. The average linkage disequilibrium (r2 ) was 0.291 ± 0.312 for all adjacent SNPs, distancing less than 100 Kb (kilobase) between markers. The average inbreeding coefficients obtained from runs of homozygosity (ROH) and pedigree analyses were 0.119 and 0.0001, respectively. Low correlation was observed between the inbreeding coefficients possibly as a result of genetic recombination effect accounted for the ROH estimates or caused by pedigree identification errors. A large number of long ROHs might indicate recent inbreeding events in the studied population. A total of 36 homozygous segments were found in more than 30% of the population and these ROH harbor genes associated with reproductive traits. The population stratification analysis indicated that this population was possibly originated from two distinct populations, which is a result from crossings between the eastern and western breeds used in the formation of the line. Our findings provide support to understand the genetic structure of swine populations and may assist breeding companies to avoid a high level of inbreeding coefficients to maintain genetic diversity, showing the effectiveness of using genomewide SNP information for quantifying inbreeding when the pedigree was incomplete or incorrect.
