Standard‐unit and realized heritabilities were computed for groat‐protein percentage using data collected from F 2 or F 6 oat ( Avena spp.) plants from intra and interspecific hexaploid oat crosses and their progenies grown in nonreplicated hills (25 to 30 plants/hill). Nitrogen percentages were determined on groat samples by the Kjeldahl procedure. The pooled standard‐unit heritability percentage for inter and intraspecific crosses was 43.0%. In one experiment, the realized and expected gains from selection were 1.0 and 1.2% groat‐protein, respectively.
