The yield of 12 spring barley cultivars (Hordeum vulgare L. and H. distichum L.) was tested under 61-cm grid, space-planted conditions and solid-seeded conditions in 1970 at two locations in Northern Alberta. A sample size of 10–20 plants was necessary to give consistent yield estimates for space-planted cultivars. Heritable differences for yield were ground in all tests, but a significant relationship between yielding ability under the two testing methods was found only at one location.
