“…One locus (EMBRA333) showed some individuals that did not amplify, so the locus was not considered in the analysis. The loci EMBRA2, EMBRA3, EMBRA10, EMBRA11, EMBRA12, EMBRA28, EMBRA38, EMBRA63, EMBRA128, MBRA157, EMBRA204, EMBRA210, and EMBRA681, present regular Mendelian segregation and are not genetic linked (Pupin et al, 2017).…”

Our aim was to verify the effect on gain and genetic diversity through the restriction of the number of trees per family in selection, in order to compose an elite population of Eucalyptus urophylla in two trials under distinct management levels.We studied 166 open-pollinated families of E. urophylla in Anhembi, Sao Paulo State, Brazil under commercial practices, and the same families in Selvíria, Mato Grosso do Sul State, Brazil under lower management level (mainly no mineral fertilization). Mortality, height and diameter at breast height (DBH) were measured. DBH was analyzed by the REML/BLUP to select the best 25 trees, with four levels of tree restriction per family (no restriction; 1; 2 and 3 per family). We evaluated heritability; genetic gain and effective size of number of total and private alleles; observed and expected heterozygosity; coancestry and fixation index. A large difference in survival (48 and 83 %) and productivity (MAI of 26 and 44 m 3 ha -1 y -1 ) was observed between trials due to the different levels of management applied. The highest restriction in number of individuals per family caused a small decrease in gain, corresponding to 7 % in the more productive trial and 3 % in the less productive one. Observed and expected heterozygosity, coancestry and fixation index were not significantly (lower than 5 %) affected by the restriction in both sites. The restriction of one tree per family allowed different alleles to be kept in the selected population and higher effective population size in order to insure variation for the next generations.

“…However, in order to be used as genetic markers, it is necessary to determine the genetic linkage and equilibrium between loci and whether the inheritance pattern follows the laws of independent Mendelian segregation. Since genetic analyses assume regular Mendelian inheritance and an absence of genetic linkage and genotypic disequilibrium between pairs of loci, this information is essential to avoid bias in multilocus estimates (Manoel et al, 2015;Pupin et al, 2017).…”

Validation of microsatellite loci for Balfourodendron riedelianum through analysis of Mendelian inheritance, genetic linkage, and genotypic linkage disequilibrium

et al. 2019

Balfourodendron riedelianum is a tropical tree endemic to the Atlantic Forest biome that is currently endangered due to forest fragmentation and extensive exploitation. Three populations of the species are conserved ex situ in a provenance and progeny test at the Luiz Antônio Experimental Station, São Paulo State, Brazil. To verify if seven microsatellite loci developed for the species can be used as genetic markers in analyses focused on conservation and sustainable use strategies, leaf tissue samples were collected from the three provenances and from 17 seed trees in one provenance. We analyzed Mendelian inheritance and genetic linkage for the 17 seed trees and genotypic linkage disequilibrium for individuals from the three provenances. For six of the seven loci analyzed, all 17 seed trees showed heterozygosity. The inheritance and genetic linkage analyses were performed using respective locus, while the genotypic linkage disequilibrium analysis was performed for the seven loci. After Bonferroni correction, none of the 75 tests showed deviation from Mendelian segregation and genetic linkage, nor did we detect genotypic linkage disequilibrium. The results suggest that six of the seven loci can be used for population genetics studies on B. riedelianum.
