High‐, intermediate‐, and low‐germinating castor seed lots were evaluated for their performance in rolled germination paper, Kimpak, sterile sand, and field soil. High‐germinating seed gave similar results on the four substrates. Low‐ and intermediate‐germinating seed lots gave maximum germination in sterile sand and field soil. High positive correlations were found among all germination substrates. Laboratory germination in tetramethylthiuram disulfide (thiram)‐treated rolled germination paper at standard temperatures and germination on Kimpak at a constant 27 C were good indicators of seedling emergence in the field.
