The inheritance of the earliness of Erbet, CI 13826 (Hockett and Eslick, 1972) was investigated at Bozeman in the field. The F2 plants were approximately 15 cm apart within rows planted 30 cm apart in 1961. In 1966 single heads from F3 plants were planted in hills spaced 60 x 60 cm apart and individual plants from these hills classified as early or late. Planting dates were 16 May and 28 May for 1961 and 1966, respectively, which are within the normal range for our location. Plots were fertilized and irrigated to prevent any growth stress. The data in Table 1 indicates the earliness of Erbet (8 days earlier in heading than the recurrent parent Betzes) is inherited as a single dominant gene, Ea. The allelism relationships with other Ea genes are unknown.
