Table 1 Best linear unbiased prediction estimates of ranges and means, estimates of variance components due to inbred lines (\({\widehat{{\upsigma }}}_{\text{G}}^{2}\)) and inbred lines x environments interaction (\({\widehat{{\upsigma }}}_{\text{G}\text{E}}^{2}\)), broad-sense heritability estimates (\({\widehat{\text{h}}}_{\stackrel{-}{\text{X}}}^{2}\)) and coefficient of variation (CV%) for 18 traits measured in this set of tropical maize lines across four environments

From: Phenotypic and molecular characterization of a set of tropical maize inbred lines from a public breeding program in Brazil
