Análise bayesiana do modelo de herança monogênica no melhoramento vegetal: um exemplo com abobrinha

Abstract: Uma estratégia comum em programas de melhoramento é conduzir estudos básicos de herança para investigar a hipótese de controle do caráter por um ou poucos genes de efeito principal, associados ou não a genes modificadores de pequeno efeito. Neste trabalho, foi utilizada a inferência bayesiana para ajustar modelos de herança genética aditiva-dominante a experimentos de genética vegetal com várias gerações. Densidades normais com médias associadas aos efeitos genéticos das gerações foram consideradas em um model… Show more

“…The use of the Bayesian approach in plant genetic improvement is still limited. Silva et al (2009) showed that calculating genotypic probabilities increased the precision of additive effect estimates and decreased the error estimate associated with the Bayesian model. Mora et al (2009) used Bayesian analysis to predict the inheritability values for forest species and concluded that the Bayesian method makes it possible to obtain low standard deviation values associated with inheritability, which makes it an important tool for the genetic assessment and inference of perennial species.…”
