| Abstract/Contents: | "Rain-out shelters have been widely used in the breeding and selection of Tall fescue[Festuca arundinacea(Schreb.)] for improved drought tolerance. Green persistence during drought is one of the important traits with obvious phenotypic variations upon which to base selection. In this study, we closely monitored and documented two consecutive generations of tall fescue populations tested in rain-out shelter trials with half-sib designs, and seek to optimize this selection procedure by a thorough genetic analysis. Bayesian linear mixed models were applied to collected datasets, and important population parameters, such as heritability and variance components, were estimated. We first reported the heritability estimates for green persistence of tall fescue in rain-out shelter selection, and then proposed a parsimonious selection scheme that incorporates either pedigree or SNP markers information to maximize selection gain while reducing space demand." |
