patch resistance must be determined. Plant breeders use heritability estimates to determine the influence of the environmental and genetic factors affecting the trait of interest and what selection procedure should be implemented to make improvements

, 2008 ). Many of these wild and weedy relatives have undesirable characteristics such as high or low flesh pH or low sugar content. Estimates of heritability and correlations among traits can help in the selection of breeding strategies and selection of

was to estimate narrow-sense heritability and phenotypic relationships among fruit metabolites in two red-fleshed watermelon populations. Methods Cultivation and field design Summer 2015: Parents. In 2015, two North Carolina watermelon populations, NC

acidity in peach ( Boudehri et al., 2009 ; Dirlewanger et al., 2009 ). Several studies have focused on estimating heritability on a progeny-mean basis expressed as the proportion of genetic variance among a progeny to that of the phenotypic variance

Fraser fir established in 1983 found significant differences among sources and among families within seed sources for all traits measured ( Arnold and Jett, 1995 ; Arnold et al., 1994b ; Jett et al., 1993 ). Heritabilities for most traits important in

conditions. Effective breeding requires both genetic variation and heritability for attributes of interest. Therefore, the objectives of this study were to assess variation for biochemical and physiological parameters associated with freezing tolerance in

different environments, it would be helpful to turfgrass breeders to know the heritability of these morphological traits in Kentucky bluegrass. Broad-sense heritability estimates the total genetic effects influencing a trait and includes additive, dominance

of inheritance of fruit softening. Resemblance among relatives is a basic genetic phenomenon, and the degree of resemblance determines heritability, which in turn facilitates the choice of a breeding method for use in genetic improvement ( Falconer

influencing the slow development of the crop in the region. Precise estimates of genetic parameters, such as the components of variance and narrow-sense heritability for economically important population characteristics in breeding programs, allow us to

fruit size. Although all yield components interact with environmental influences to produce total yield, from a breeding point of view, there are key components that are likely to be better correlated with yield and are more heritable. We found few
