  • a Unweighted average ± standard error.

  • b For each pair of results in the table, the data on the top line were collected in November 2000–January 2001 and the data on the bottom line were collected in July 2003.

  • c Cumulative effect due to TP5 element being present in the Su(var)2054/Cy Roi stock for many generations.

  • d Zygotic effect due to TP5 being present with factors from the Su(var)2054/Cy Roi stock in the test generation.
