Comment
Associated with seedling resistance to spot form of net blotch in combined population of two-row and six-row barley. In a two-rowed subpopulation, phenotypic R^2 was 3.5, additive effect was 0.313, and p-value was 9.00E-03. In a six-rowed subpopulation, phenotypic R^2 was 3.5, additive effect was 1.15, and p-value was 4.55E-04.
