Tassel measurements on the wild type and baf1-ref mutants in the B73 background (BC2) and the wild-type and baf1-IL in the A619 background (BC1). Average numbers (sd in parentheses). All compared values are in the same genetic background. *t test, P = 0.041; **t test, P ≤ 0.0001; ***t test, P = 0.0008; ****t test, P = 0.0009. n.d., not determined.
