The winter barley variety ‘Mo. B‐475’ was crossed with the large seeded spring varieties, ‘Larker’ and ‘Trophy.’ Parents, F 1 , and F 2 were grown in the greenhouse in the first experiment and parents, F 1 , F 2 , and F 3 progeny lines were grown in the field in the second experiment. Heritability of kernel weight ranged from 25.3 and 25.9% when measured by parent‐progeny correlation to 43.1 and 46.0% when measured by variance of F 2 (broad sense). Observed genetic advance ranged from 6.5 to 14.2% depending on the method of calculation and compared closely to the predicted.
