The development of linkage disequilibrium (LD) maps is very important for understanding the nature of non-linear association between phenotypes and genes, as LD can be defined as the non-random segregation of a pair of alleles at polymorphic sites. Canchim is a composite beef cattle breed which was developed in the 1960's by the crossing of Bos indicus (3/8) x Charolais (5/8) animals. The objective in this study was to analyze the extension of LD maps from a Canchim beef cattle population. |

The objective of this study was to estimate the spatial repeatability coefficients of Bertholletia excelsa fruits and nuts using different statistical methods, as well as to define the minimum number of fruits and nuts to be evaluated for the selection of superior genotypes. Twenty-one genotypes in the 2017 crop and 28 genotypes in the 2018 crop were evaluated. From each genotype, 10 fruits and 10 nuts per fruit were sampled. Seven fruit traits and three nut traits were measured, which were used to estimate repeatability coefficients by four statistical methods: 1) analysis of variance; 2) main components based on the correlation matrix; 3) principal components based on the covariance matrix and 4) structural analysis based on the correlation matrix. Estimates of repeatability coefficients varied among crops, traits and estimation methods. In general, the coefficients presented moderate magnitudes, and the methods based on principal components provided the highest estimates. For the most economically important traits for the Brazil nut market, minimum sampling of 8 fruits and 7 nuts per genotype is required to select genotypes with determination coefficients above 85%. |
