Heritability and Genetic Advance for Kernel Weight in Barley (Hordeum vulgare L.)1
- D. N. Borthakur and
- J. M. Poehlman2
The winter barley variety ‘Mo. B-475’ was crossed with the large seeded spring varieties, ‘Larker’ and ‘Trophy.’ Parents, F1, and F2 were grown in the greenhouse in the first experiment and parents, F1, F2, and F3 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 F2 (broad sense). Observed genetic advance ranged from 6.5 to 14.2% depending on the method of calculation and compared closely to the predicted.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
