*Stability-safety index for each clone is calculated at p=0.01 by Eskridge's method and use of Shukla's stability-variance parameter. To compare two negative indices, the index with the lower absolute value is the greater of the two.

†LSD for location means=1.282 TS/H at p=0.10.

‡CV=coefficient of variation.
