Character means and heritabilities.

Summary statistics for morphological, reproductive and physiological characteristics in sunflower recombinant inbred line (RIL) cultivar (cmsHA89) x wild (ann1238) hybrid populations grown in control (CW) and low water (LW) treatments. Least-squares means, standard deviations (SD), and heritability components were calculated using a restricted maximum likelihood analysis. Broad-sense heritability is the proportion of line (RIL) to total variance.
