* 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 lowest absolute value is the greater of the two.

† LSD for location means = 2.8 KS/T at p = 0.10.

‡ CV = coefficient of variation.
